This is an article about the injector for you, and tell you the brand name of the injector and the reputable supplier. This article is divided into the following sections:1. What is fuel injection?2. Brand introduction of fuel injection3.9 high quality fitech fuel injection suppliersFirst, let's start with the first part. What is fuel injection?About fuel injectionThe fuel injector is a precision device with very high processing precision, which requires a large dynamic flow range, strong anti-blocking and anti-pollution ability and good atomization performance.The spray characteristics of the fuel injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle. These characteristics should meet the requirements of the diesel combustion system to complete the formation and combustion of the mixture, and to achieve higher power and thermal efficiency. It has the following effects:1. Increase oil pressure (constant pressure): Increase the injection pressure to 10 MPa to 20 MPa.2. Control injection time (timing): Inject oil and stop injection at the specified time.3. Control the fuel injection amount (quantitative): According to the working condition of the diesel engine, change the amount of fuel injection to adjust the speed and power of the diesel engine.In addition, fuel injection can be divided into the following categories:(1) Shaft needle type electromagnetic fuel injectionWhen the fuel is injected, the armature drives the needle valve to rise from its seat surface by about 0.1 mm, and the fuel is ejected from the precision gap. In order to fully atomize the fuel, a needle of the injection shaft is ground at the front end of the needle valve. The injector suction and fall time is about 1~1.5ms.  (2) Ball valve type electromagnetic fuel injectionThe valve needle of the ball valve is light in weight and has a large spring preload force for a wider dynamic flow range. The ball valve has an automatic centering function and good sealing. At the same time, the ball valve simplifies the structure of the metering part and helps to improve the accuracy of the fuel injection.   (3) Chip valve type electromagnetic fuel injectionrThe light-weight valve and bore seats are combined with a magnetically optimized injector assembly that allows the injector to have a wide dynamic flow range and high resistance to clogging.     (4) Injector with lower fuel injectionBy adopting the bottom oil supply mode, since the fuel can continuously flow out from the upper portion of the injector through the inner cavity of the injector, the cooling effect on the metering portion of the injector is very obvious, so that the generation of the air resistance can be effectively prevented, and the hot start of the automobile can be improved.

Microwave Sterilization Equipment is effective against COVID-19 virus，microwave sterilization time is short and the efficiency is high.It has been widely used in anti-epidemic work, providing an important guarantee for active anti-epidemic.New coronary pneumonia (COVID-19) is a new type of coronavirus that has not previously been found in humans. Since it was discovered in Wuhan, China in December 2019, it has spread to 114 countries with more than 120,000 confirmed cases worldwide. Economy, culture, politics, etc. have all had an impact. So far, WHO has declared that the epidemic is a global pandemic.The new type of coronavirus that caused this pneumonia epidemic is an enveloped virus that is extremely contagious. During the year-long anti-epidemic process, how to prevent the COVID-19 virus? How to completely eliminate the COVID-19 virus? Waiting for questions, the researchers gave answers to the following classic questions to help you better understand the COVID-19 virus.1.Can Covid-19 Spread Through Food?The Chinese seafood market has been the place where the epidemic broke out one after another. Whether the virus is spread through food has become a major concern of all countries. Experts from the Institute of Virology of the Chinese Center for Disease Control and Prevention found that seafood itself does not carry the virus, but it is in the process of transportation and sale. , Will be contaminated by virus carriers.Although the COVID-19 virus is not spread through food, it may spread through food packaging. Therefore, when buying food, choose a market with formal and complete disinfection measures. Regarding the outer packaging of food, disinfection and sterilization work should be done in advance. The cutting boards and knives for handling raw and cooked food should be separated and hands should be washed in time. As long as the meat is thoroughly cooked or industrial microwave sterilized during the food preparation process, it is safe to eat.2.Can You Contract The Coronavirus Disease By Touching a Surface?The surface of the contact object can transmit the new coronavirus. The transmission of the new coronavirus includes droplet transmission and contact transmission.Secondly, contact transmission means that after touching an object carrying the virus, you must wear a mask when you go out during extraordinary times. After entering the mall market, you must disinfect your hands and the surface of clothing. Therefore, for the safety of yourself and others, you must contact others. Keep your distance and pay attention to hygiene and safety. For body surface disinfection, alcohol disinfectants can be used, and object disinfection can be sprayed with disinfectant, which can effectively prevent new coronavirus infection.However, not all contacts will be infected with the virus. Taking safe protective measures is the key to preventing infection with the new crown virus.The new coronavirus has been detected on the outer packaging of food3.Can A Microwave Kill The Coronavirus?Full automatic microwaves can kill the new coronavirus. After the outbreak began, a large number of researchers around the world have developed effective methods to kill the new coronavirus. Microwave sterilization has achieved preliminary results in the research of eliminating COVID-19 virus.Automatic microwave sterilization is the result of the combined effect of microwave heating and biological effects. Microwave equipment can make the virus grow normally and stably reproduce the nucleic acid RNA and deoxyribonucleic acid DNA. It is caused by the relaxation, breakage and recombination of several hydrogen bonds, thereby inducing genetic mutation, or chromosome aberration or even breakage, which is very good for killing the new coronavirus effect.Ordinary sterilization methods require tens of minutes at a high temperature of 120-130 degrees, while microwave sterilization can be effective in only 3 minutes at 80-100 degrees, and the rising temperature can be as high as 140 degrees, so it is one This is a very effective way to eliminate the COVID-19 virus.4. Is Microwave Sterilization Equipment Effective Against Covid-19 Virus?Microwave Sterilization Equipment is effective against COVID-19 virus. The new coronavirus is a kind of enveloped virus. High temperature is not conducive to the survival of the virus. Microwave sterilization equipment uses heat sterilization to eliminate the virus.In 2003, the World Health Organization conducted a study and found that the SARS virus (coronavirus) can be inactivated by heating. 15 minutes at 56 degrees Celsius (132 degrees Fahrenheit) can reduce live viruses by 10,000 times3. The higher the temperature, the faster the process. This study just confirmed that microwave equipment can be sterilized by high temperature.Affected by the epidemic, masks, gloves, protective clothing, etc. used for medical protection must undergo rigorous disinfection and sterilization. Microwave sterilization equipment can change the permeability of cell membranes. As a result, bacteria are malnourished, cannot metabolize normally, and their growth and development are hindered. , To achieve complete sterilization.In addition, Microwave Sterilization Equipment can also sterilize reusable items.Microwave sterilization equipment5.Does Microwaving Masks Disinfect Viruses?High quality microwave can sterilize masks. After the epidemic began, all equipment used for medical protection was sterilized and sterilized by microwave sterilization equipment. Microwave sterilization was achieved by high temperature sterilization.Of course, when sterilizing medical equipment such as masks and protective clothing, professional industrial microwave sterilization equipment is required for sterilization. Although household microwave ovens also have certain sterilization and anti-virus effects. Microwave ovens are not professional equipment for sterilization of masks. The heating of microwave ovens will destroy the protective structure inside the masks. Which greatly reduces the effectiveness of protection against the new crown virus, and there are certain safety risks. Therefore, it is not recommended to use household microwave ovens to disinfect masks.Protective clothing and Masks sterilized by microwave sterilization equipment6.Should I Microwave My Mail?Although household microwave ovens can kill the COVID-19 virus, paper products such as mail cannot be put into the microwave oven. The energy density of the microwave is large enough to allow the temperature of the paper to rise above the ignition point. Putting flammable paper mail in a microwave oven for heating and baking will cause a fire, so never use a microwave to sterilize the mail.Canadian infectious disease expert Dr. Sumon Chakrabarti pointed out that the vast majority of people are infected with the COVID-19 virus through the respiratory system. If an infected person sneezes into your email, touches your mouth or nose after touching your hand, it is very likely to be infected. It is recommended that for mail that cannot be disinfected by professional microwave sterilization equipment, do not touch your face after opening the mail, and wash your hands immediately after reading it.7. What Are The Advantages Of Microwave Sterilization Machine To Eliminate Covid-19 Virus?The microwave sterilization time is short and the efficiency is high.Microwave sterilization is the result of the combined effect of microwave heating and biological effects. During the epidemic, the medical equipment required for sterilization has greatly increased, and all need to pass rigorous sterilization treatment. The microwave sterilization equipment has a fast sterilization speed. It improves the sterilization quality and provides convenience for medical protection.Low-temperature drying and sterilization to maintain nutrients.Although the food itself does not carry the new coronavirus, the risk of contracting the new coronavirus from food is very low, but recently China has detected the presence of the new coronavirus on the outer packaging of imported seafood. Therefore, all imported and exported foods in China are now strictly sterilized through microwave sterilization equipment.Microwave has the double sterilization effect of rapid heating with thermal effect and non-thermal effect. The sterilization can obtain the required drying and sterilization effects at a relatively low temperature and a short time. It retains food nutrients and flavors such as color, fragrance, taste and shape.Energy saving.During the epidemic, all sectors of society are affected by the epidemic, and we should pay more attention to the application of energy. When the microwave sterilization equipment is working, the microwave directly treats the food, and the heating box itself is not heated, so there is no additional heat loss, which saves energy and electricity. Generally, 30-50% of electricity can be saved.Sterilize evenly and thoroughly.Microwave has the penetrating performance, the surface and the inside work at the same time, which can ensure that the internal and external temperatures reach the required value together, so the drying and sterilization of food and medical equipment are uniform and thorough.Easy to control and easy to realize automated production.Microwave sterilization equipment is simple to operate, easy to control, has no thermal inertia, and can be processed according to different food process specifications, reducing production operators and reducing production costs during the anti-epidemic period.

In the machining process, cutting is the most common processing method. There are many different cutting methods, such as manual cutting, die-cutting, digital cutting, etc. Different cutting methods apply to different types of work. Manual cutting is flexible and convenient, but the cutting quality is disappointing, the error is enormous, and the productivity is low. Die-cutting offers a fast and inexpensive way to cut, allowing for high volume production. But as consumer demands increase, more refined finishes have become the new standard for fabricators, and digital cutting allows for more complex shapes to be cut and delicate cuts to be made.Digital knife Cutting Machines are designed for industrial digital conversion, with intelligent slicing, built-in weighing, and many other unique features. Manufacturers in selecting digital knife cutting machines to integrate various factors, if you are not a professional in the machinery industry, there is not much knowledge of machinery, even if you have collected a lot of information, it is difficult to make the right choice. When choosing equipment, you should compare the quality of the equipment as well as after-sales aspects. The essential components of the digital knife cutting machine.1. The body, which carries all the parts of the machine2. Sliding plate or slide can move numerically to achieve processing3. Sliding plate drive mechanism, including motors, couplings, screws, nuts slide plate, etc., through the form of movement from rotation to linear movement of the slide4. Control system, including motor drive, main control board, software, etc., is the core of the machine. According to the basic structure of the equipment, you can choose from the following aspects.   6 Ways Choose Digital knife Cutting Machines1.Bed structure2.Accessories3.Installation process4.Actual usage cost5.Multifunctionality6. Warranty terms Bed structureThe high-quality bed is an essential factor in ensuring that the cutting machine can run continuously and stably. If the bed quality is poor, work will shake, resulting in poor cutting accuracy, so be sure to choose a greater self-weight, reasonable structure of an all-welded bed. AccessoriesOnly the use of high-quality accessories equipment has the excellent quality, can ensure continuous and stable work. The more critical accessories include the electrodes, the drive method, and the working platform. The dual-motor drive and the dual-frame drive method can ensure the accuracy of the cutting machine for a long time. The vacuum adsorption platform should try to choose a high-power vacuum pump to ensure that the material is fixed firmly during the processing. Platform plane detection system can effectively extend the service life of the working platform and provide a good cutting effect. Other types of accessories should also choose the regular brand.  Installation processGood or bad installation technology is the core factor reflecting the production quality of a machine. Even if you choose high-quality accessories, you still can not produce high-quality products if the installation is not reasonable. A qualified installation should be scientific, clean, and tidy.The actual cost of useThis problem is a critical point. If the cutting machine is processing low yield, high energy consumption, and high scrap rate, it will significantly disadvantage your output. So whether it is to control your costs or improve product quality, choose the actual use of the low-cost cutting machine is very necessary. VersatilityVersatility determines the range of work that the cutting machine can perform, the types of materials that can be processed, etc. A fully functional cutting machine can make your investment more valuable. Warranty termsThis issue is a crucial point in the after-sales service, which determines the warranty coverage of the cutting machine and is an essential factor for you to save on maintenance costs. As an R&D and production company engaged in the machinery industry for many years, we always insist on producing high-quality machines. We hope we can help more factories to realize intelligent production. We will provide you with high-quality Digital knife Cutting Machines and share more knowledge about choosing the machine.

With the footsteps of the cold winter, we are about to enter a new year. Are you ready to go out for a trip? Then you may need a box for carrying your luggage, which is the suitcase.A suitcase is a box that is carried at the time of exit and is used to place items. It is one of the types of luggage. Usually the suitcase is used to store the clothing, personal care items and souvenirs needed on the trip.Early luggage was made of wood or other heavy materials. With the popularity of air travel, the material of the luggage tends to be lighter in hard plastic or cloth. Most of the models also come with built-in small wheels, which can be easily pulled by the lever. After 2010, there are also 4 small wheel suitcases. In addition to the 360-degree rotation, it can be easily pushed on the ground without any effort.In addition, the trunk can also be divided into hard-shell luggage and soft-shell luggage according to the outer casing. The hard-shell luggage is more resistant to falling and is suitable for luggage that requires more protection. The soft-shell luggage is usually lighter than the hard-shell luggage and has a more flexible capacity. However, the zipper position of the soft-shell suitcase is more likely to burst due to too many objects inside.Are hard or soft suitcases better?Both hard and soft leather materials have their own advantages and disadvantages. According to the World Travel website, the reasons for the support of soft and hard luggage, although the two believe that the benefits can not be replaced by the counter, but you should pay attention to the luggage The choice, in fact, is best used flexibly according to your shopping destination and the purpose of tourism.Hard luggage:In many people's eyes, the hard suitcase looks really cumbersome, especially in the empty box, it is already 6,7 kg. However, hard boxes are much more protective than soft boxes. People who like to buy fragile objects such as art, alcohol, olive oil, etc. in foreign countries, it is best to use hard suitcases.Because if you travel in a soft box, when you buy these things, you still have to spend a lot of time thinking about how to pack them, so that these fragile items will not be broken.Soft suitcase:Soft leather suitcases are generally made of fabric or leather. The main advantage is that the overall quality is lighter, the carrying is more convenient, the flexible space is wider, and more objects can be stuffed, but most of the side uses zipper design. There may be a risk of blasting the object, and the soft box is more susceptible to squeezing than the impact, and the item is at risk of crushing.What is the best suitcase?I feel that the trolley case has developed over the years and all brands are inevitably converging. It is also normal to think about it. The cost-effective materials that can be used in the trolley case are just a few. Common PCs, alloys, PP, ABS, and ordinary plastics. Locks evolved from ordinary password locks to TSA locks, and the wheels became more and more stable and effortless. In addition to this, the appearance and color of the changes are constantly changing, and only in these fine details can be worked hard. It may be for this reason, so I was surprised when I saw the smart box.The smart boxes on the market can be roughly divided into three types: the first one: the free type. The box does not need to be pushed, and will follow you behind yourself. It looks very trendy and the problem is obvious. What should I do when crossing the road? What should I do if the crowd is crowded? What about a narrow space? Pushing the box basically has to be carried out in crowded places such as airports and stations. This kind of box is very tasteless. Second, riding type. Similar to the first one, this time someone can ride on the box and let the box take people away. The first kind of problem will be encountered, and an additional syndrome will be sent. It is understandable that a child can sit on a rocking cradle. It is magical for an adult to ride a box. Okay? The third type is the intelligent unlock type.

After years of development, 100G applications have formed a variety of technology types and alliances, whether it is the standardized ieee802.3bm or the 100G application model launched by SWDM, MSA and other organizations. There are many kinds of interfaces and application technologies supporting 100G, and each has its own characteristics. For the practical application of the data center, the distance between the connection points of most data centers does not exceed 500 meters. From a large number of 100G interface models, we have selected four types that are most likely to be used in data centers for further analysis for users who need to deploy 100G for reference. 1. 100GBase-SR4 100GBase-SR4 complies with the new standard ieee802.3bm issued in 2015. It uses 4 channels composed of 8-core multimode fiber for parallel transmission. Both multimode OM3 and OM4 optical fibers support 100G applications. The interface adopts 12 core MPO interface. The middle four core optical fiber does not need to be used. Each channel supports 25G. The transmission model is completely consistent with 100GBase-SR4 in ieee802.3ba. The optical transceiver adopts 100G QSFP28 SR4. This model can use conventional OM3 and OM4 multimode optical fibers to support 70m and 100m distances of 100G applications respectively. 2. 100GBase-SWDM4 SWDM (Short Wavelength Division Multiplexing) transmits four wavelength bands of optical signals over a single core of multimode fiber. The principle of WDM is similar to CWDM on single-mode, but SWDM is the first application of WDM technology on the short wavelength band of multimode fiber. It can be referred to the transmission principle model in the following figure:  The main transmission window of traditional OM3 and OM4 multimode fiber is defined at 850nm. If SWDM technology is adopted, four windows are required to transmit optical signals, and the four wavebands still use VCSEL vertical cavity surface emitting lasers with high cost performance. In order to improve the overall bandwidth, the bandwidth of the new generation multimode fiber WBMMF(Wideband Multimode Fiber) is increased. In WBMMF, the highest bandwidth performance is around 880nm band, and the highest bandwidth point is higher than that of traditional OM4 multimode fiber. The SWDM technology can also use OM4 optical fiber as the transmission medium, but the transmission distance should be reduced accordingly. Compared with the SR4 model, SWDM4 requires only 25% of the optical fiber.3. 100GBase-PSM4 100GBase-PSM4 adopts single-mode optical fiber parallel transmission mode. Each 100G model adopts 8-core single-mode optical fiber to form four independent channels. The interface adopts 12 core MPO interface, in which the middle 4-core optical fiber of MPO interface is not enabled, and each channel supports 25G. The optical fiber transmission model is similar to 100GBase-SR4. The biggest difference is that PSM4 adopts single-mode optical fiber as the transmission medium and laser light source 1310 window. The optical transceiver also adopts QSFP28, and the connector adopts MTP / MPO single-mode APC. At present, 100GBase PSM4 has not been recognized by IEEE standardization organization, and is mainly promoted by PSM4 MSA alliance. 4. 100GBase-CWDM4  100GBase-CWDM4 is a 100G transmission model based on single-mode coarse wavelength division multiplexing(CWDM) technology. The fiber optic transceiver uses a single-mode laser light source with LC duplex interface, and supports four long wavelength bands of signal transmission on each core fiber, these four emission windows are 1271nm,1291nm,1311nm,1331nm, and each band transmits 25G. 100GBase-CWDM4 model is also used QSFP28 optical transceiver.Compare to traditional single-mode 10KM transceiver with high cost, the 2KM QSFP28 100G CWDM4 transceiver has a competitive price.   5. Summary  Different types of data centers determine different needs. Not all data center users currently have the need to deploy 100G, so what types of users need to deploy 100G networks the most? To answer this question, we can divide data centers into two major categories, IDC (Internet Data Center) and EDC (Enterprise Data Center). Relatively speaking, some IDC data centers have more urgency to deploy 100G backbone networks, such as the data centers of large interconnection companies or carriers or some scaled cloud computing data centers. In terms of current price, although the wiring cost of multi-mode 100G based on SR4 is relatively high, the overall price has certain advantages, especially the price of SR4 optical transceiver is significantly lower than that of other types. Meanwhile, the price of optical transceiver based on CWDM single-mode is significantly higher than that of the other three types. The overall price difference between PSM4 and SWDM is small. As the SWDM alliance participated by a small number of optical transceiver manufacturers, it is not a public technology at present, and the market price remains relatively high temporarily. However, from the perspective of technology and cost composition, there is still a large room for price decline of SWDM, and this product has a certain market potential in the future.

The close cooperation between the two parties has enabled the hydrogen-powered vertical takeoff and landing fixed-wing UAV to move from concept exploration and critical technology research to the stage of engineering and radicalization.5G Networked Drones In April, JOUAV, together with China Mobile (Chengdu) Industry Research Institute, released the JOUAV 5G Networked UAV solution. 5G Networked Drones is deeply integrated with the 5G Networked system. It can be applied in many fields such as water patrol, forest patrol, and grass protection, Border patrol and defense, coastal security, emergency disaster relief, police law enforcement, aerial security, digital city, traffic patrol, etc. CW-15 V2 + Industrial Camera Solution In March, JOUAV released the CW-15 V2 UAV, which can be as simple and easy to use as a consumer-grade product and can be used with partners for secondary development of loads and software.JOUAV CW-15 V2 UAV is equipped with a 100 million pixel Feisi camera, which can achieve better than 2CM resolution tilt photography and achieve "high efficiency and high accuracy. "It can realize multiple uses of one data, change the application of mapping and geographic information in various industries, and build a broad new application model.Cooperating with Wuhan RAMAP to exhibit aerial survey software solutionsOver the years, JOUAV and Wuhan RAMAP have continuously launched aerial survey system software. For example, in 2017, our two companies jointly established the 1:500 camera-free photogrammetry system, which saved many fieldworks for most photogrammetry users. It is highly praised within.Now, after three and a half years of hard work, combined with the latest photogrammetry development trends and trends at home and abroad, the two companies have jointly developed a new generation of realistic 3D system and 2D integrated system, providing a more efficient and scientific solution for the photogrammetry industry. One of the new generation of the realistic 3D system, from multiple images, after a series of efficient automated processing, to get high precision and high fidelity of the actual 3D model, processing, you can join the ground control points or air control (differential GPS) to get the product with geographic coordinates. After further optimization by GPU technology and intelligent cluster technology, the efficiency of the product has been dramatically improved, and the product effect, flat plane, and straight line, so that the realistic 3D to the natural direction to a higher level. The 2D integrated system, on the other hand, starts from the image of vertical photography, and after a series of efficient automated processing, gets high precision and high fidelity DSM and TDOM (accurate shot) ideas, including the functions of air three, image control free, DSM dense matching, proper shot correction, seam line finding, color leveling, and light leveling.In addition, the JOUAV UAV ground charge vehicle was also presented at the exhibition. The ground accusation vehicle can highly integrate the JOUAV UAV platform, mission payload, ground command system, highly integrated, fast response; reasonable layout, convenient operation; 100 km long dual link; durable and reliable, uninterrupted operation; multiple redundancy, safe operation, and other features. Platform strategy is the global dynamic optimization that JOUAV has been pursuing. JOUAV advocates and drives the "point, line, surface, and body" in the industrial UAV ecosystem to develop and connect extensively to form a network effect, thus accelerating the innovation of technology and products.JOUAV Chairman Ren Bin said that the new generation of industrial drones is safe, reliable, and empowering to all industries and "popularized" by the low cost of use. "Only in this way can drones become "industry-based tools" in the true sense of the word.

1. Introduction of optical moduleAs an important part of fiber optic communication, optical module is an optoelectronic device that realizes the function of photoelectric conversion and electro-optical conversion. To be precise, optical module is the general name of several types of modules, including optical transmitting module transmitter, optical receiving module receiver, optical transceiver module transmitter and optical forwarding module transmitter. Generally, the optical module we call generally refers to the integrated optical transceiver module, namely, optical transceiver. ① Working principle of optical transceiver Optical transceiver works in the physical layer of OSI model and is one of the core devices in optical fiber communication system. It is mainly composed of optoelectronic devices (optical transmitter, optical receiver), functional circuit and optical (Electrical) interface. Components of an optical transceiver  Basic principle: the transmitting interface inputs an electrical signal with a certain code rate. After being processed by the internal driving chip, the driving semiconductor laser (LD) or light emitting diode (LED) emits a modulated optical signal with a corresponding rate. After being transmitted through the optical fiber, the receiving interface converts the optical signal from the optical detection diode into an electrical signal, After passing through the preamplifier, the electrical signal of the corresponding code rate is output.    ② Key parameters of optical transceiver The key technical indicators of the optical transceiver mainly include: transmitting optical power, receiving optical power, overload optical power, maximum receiving sensitivity and extinction ratio. A. Transmitting optical power: refers to the optical power output by the light source at the transmitting end of the optical module under normal working conditions, which can be understood as the intensity of light, and the unit is w or MW or DBM. Where w or MW is the linear unit and DBM is the logarithmic unit. In communication, we usually use DBM to represent optical power, and the optical power of 0dbm corresponds to 1MW.B. Receiving optical power: refers to the average optical power range that can be received by the receiving end component under the condition of a certain bit error rate (BER = 10-12). The upper limit value is the overload optical power, and the lower limit value is the maximum value of reception sensitivity.C. Overload optical power: also known as saturated optical power, it refers to the maximum input average optical power that can be received by the receiver component when a certain bit error rate (BER = 10-12) is maintained at a certain transmission rate (unit: DBM). It should be noted that the photocurrent saturation of the photodetector will occur under strong light irradiation. Therefore, strong light irradiation should be avoided as far as possible to prevent exceeding the saturated light power.D. Receiving sensitivity: refers to the minimum average input optical power that can be received by the receiving end component when a certain bit error rate (BER = 10-12) is maintained at a certain transmission rate (unit: DBM). Generally, the higher the rate, the worse the reception sensitivity, that is, the greater the minimum received optical power, and the higher the requirements for the receiving devices of the optical transceiver.E. Extinction ratio (EXT): it is one of the important parameters used to measure the quality of optical modules. It refers to the ratio of the optical power P1 (when the laser emits all "1" codes) to P0 (when the laser emits all "0" codes) under the condition of full modulation, and the unit is dB. It is not that the greater the extinction ratio, the better the quality of the optical module, but that the optical module with an extinction ratio can meet the IEEE 802.3 standard is the better.       ③ Example of optical transceiver information on the switch:  Cisco switch interface optical transceiver information: Huawei switch interface optical transceiver information:2. Classification and packaging(form-factor) of optical transceivers ① Transmission rate: The current common types of optical modules are as follows:400GE optical module200GE optical module100GE optical module40GE optical module25GE Optical Module10GE Optical ModuleGE Optical ModuleFE Optical Module ② Form-factors: The higher the transmission rate, the more complex the structure, resulting in form-factors. For example, SFP/eSFP, SFP+, SFP28, QSFP+, CXP, CFP, QSFP28, etc. l  SFP (Small Form-factor Pluggable) optical module: small pluggable SFP module supports LC fiber connector.l  SFP + (Small Form-factor Pluggable plus) optical module: refers to the SFP module with increased rate. Because of the increased rate, it is sensitive to EMI and smaller than the SFP module.l  XFP (10GB Small Form-factor Pluggable) optical module: "X" is the abbreviation of Roman numeral 10. All XFP modules are 10GE optical modules. The XFP optical module supports LC optical fiber connectors. Compared with SFP + optical module, XFP optical module is wider and longer in size.l  SFP28 (Small Form-factor Pluggable 28) optical module: the interface package size is the same as that of SFP +, and supports 25G SFP28 optical module and 10G SFP + optical module.l  QSFP+ (Quad Small Form-factor Pluggable) optical module: four channel small hot pluggable optical module. QSFP + optical module supports MPO optical fiber connector, which is larger than SFP + optical module. Fiber Mall 40G QSFP+ Optical Transceivers l  CXP (120 GB/s Extended Capability Form-factor Pluggable) optical module: it is a hot-pluggable high-density parallel optical module standard. It provides 12 channels in the transmit and receive (TX / Rx) directions. It is only applicable to short-range multimode links.l  CFP (CENTUM Form-factor pluggable) optical module: the size is defined as 144.75mm × 82mm × 13.6mm, which is a new optical module standard with high speed, hot-pluggable and supporting two applications of data communication and telecommunication transmission.l  QSFP28 (Quad Small Form-factor Pluggable 28) optical module: the interface package size is the same as QSFP+, and supports 100G QSFP28 optical module and 40G QSFP+ optical module. ③ Single-mode or muti-mode? The optical fiber is divided into single-mode optical fiber and multi-mode optical fiber. The single-mode optical module is used together with the single-mode optical fiber. The single-mode optical fiber has wide transmission frequency bandwidth and large transmission capacity, which is suitable for long-distance transmission; The multi-mode optical module is used together with multi-mode optical fiber, and multi-mode optical fiber has mode dispersion defect, and its transmission performance is worse than that of single-mode optical fiber, but the cost is low. Therefore, it is suitable for small capacity and short-distance transmission. ④ Wavelength The central wavelength refers to the waveband used for optical signal transmission. At present, there are three kinds of common central wavelengths: 850nm, 1310nm and 1550nm.850nm: mostly used for short distance transmission (≤ 2km)1310nm and 1550nm: mostly used for medium and long distance transmission (>2km) ⑤ Transmission distance According to the different transmission distance of optical module, it can be divided into:Short distance optical module: ≤ 2kmMedium distance optical module, 10 ~ 20kmLong distance optical module: ≥30km.The transmission distance of optical modules is limited mainly because of the loss and dispersion of optical signals during fiber transmission. ⑥ Photoelectric module The photoelectric module is usually called electric port module or RJ45 SFP module. Unlike the optical module, the electric port module does not carry out photoelectric conversion. Through the switching of the electric module, the two optical interfaces can be connected with a network cable.RJ45 Copper SFP Module  3. Development and evolution of optical transceiversIn the current physical architecture network of mainstream data centers, Spine-Leaf (Clos network architecture) architecture is commonly followed. Usually 10GE interface is used as the access side server docking, and 40GE interface is commonly used for the uplink on the Leaf side. In large data centers, it has been common to use 25G as the mainstream access and 100G uplink. In scenarios requiring high computation and high bandwidth, GPU servers have been using 100GE and even 200GE access. Data center switch interconnects are evolving to large-scale 400GE interconnects.The development of Ethernet has undergone rapid changes from 1Mbit/s, 10Mbit/s, 100Mbit/s (FE), 1Gbit/s (GE), 10Gbit/s (10GE) to 40Gbit/s (40GE), 100Gbit\s (100GE), and with the rapid development of big data, smart cities, mobile Internet, cloud computing, network traffic has shown exponential growth. The thirst for continuous growth of bandwidth will require higher bandwidth rates, and optical modules will develop rapidly.

This is because of their policy of valuing quality materials and services. While smaller businesses and companies can get into their directories, they need more capital. These larger companies and factories are able to sell their products to buyers in a large wholesale market.Global source provides bulk products, not individual products. Because of their policy, these larger factories sell their products in bulk at wholesale prices. This makes the overall price of each product cheaper. These products are not as profitable as shipping them directly from factories and warehouses. This means you can save even more money when you order in bulk from global suppliers.Be sure to ask the supplier in advance if the product is in stock and how soon it can be delivered. ArkartechArkartech is another Chinese wholesale website that outsources its inventory. They do have their own inventory and not rather depend on vendors to bring in their own inventory. This is why many smaller businesses are present on the Arkartech. You can easily find many items of different categories from both small vendors and medium-sized vendors. AlibabaAlibaba has several large businesses, several small businesses, and even some suppliers who work from home. This diversity and large number of suppliers can be on the site, which can be confusing because they do not all offer the same quality of services and materials.However, a general rule of thumb is to use the product review section as well as the vendor to determine if the purchase is worth it. You must be careful to select real reviews, not paid or fake ones, which may have been fabricated by vendors to make their profile look more attractive. DhgateDHgate has no minimum requirements to make it easier for buyers. Buyers can buy only one or two items. Many wholesale suppliers offer discounts for wholesale projects. So, if you increase your quantity, the supplier will probably give you a discount. That means the more you buy, the lower the price.  Yiwu goYiwu go provides an opportunity for small and medium-sized enterprises to sell goods. You will find several kinds of yiwu Go, from which you can choose the product you want.Most of these products come from domestic Chinese companies. Most suppliers come from yiwu international trade city. This means that these suppliers may have their own factories and workshops where they produce their own products. Techniques of choose and buy1. It is to understand the source of materials and accessories used. Soybean milk machine generally USES better materials and accessories, and there are some imported accessories. 2. Check the power plug and wire, etc., and buy products certified by national quality and safety system, such as 3C certification and the Europe Union CE certification. The soybean milk machine that sells in the market must accord with the requirement of national safety standard, must carry CCC attests mark, but the product that sells in a few markets still did not pass CCC attests now, you must recognize and hold. 3. Perfect service system is a good guarantee of product quality, so there should be pre-sale, in-sale and post-sale services as well as network density to meet the service requirements. 4. Crushing effect: whether the performance of the motor and the design of the blade are reasonable determines the degree of bean crushing and the level of pulp yield. 5. Technology of mesh cover: good mesh cover mesh according to the herringbone cross arrangement, dense and uniform. 6. Look at the shape of the heating tube: the lower half of the ideal soybean milk machine heating tube is a small semicircle, easy to wash and load and unload the mesh cover. 7. See whether to use the "golden ratio" design: the ratio of the amount of beans to the amount of water, the water temperature of the grinding, the grinding time, the cooking time and other factors ConclusionThere are many types of soybean milk machine and you need to carefully select the brand you are satisfied according to the purchasing techniques mentioned in this article.
