XK-GX2 Optical fiber communication comprehensive training kit for vocational training
I.Main characteristics
1. This training system is in the point of view of the whole communication domain system, and adopts modular design which display the communication relatived knowledge through “communication building blocks” form, besides can support the students researching the building blocks, it is also convenient for the second development of the hardware circuit and easy for upgrading and expanding the experiment system.
2.Each module shall use the upper and lower two layers protective cover to protect completely, the upper cover is a transparent shell which is easy for the students to observe and do experiment, for the convenience of the experiment teaching and module repair, shall adopt the bayonets (no need the screws)to connect the module upper and lower two layer protective shell which are easy disassembled.
3.Equipped with specialized synchronous module, can display bit synchronous, frame synchronous, carrier synchronous function, and the bit synchronous contains the filter mehtod and full digital PLL two implementation methods
4.Can build all kinds of different communication system among different experiment boxes, can simulate the signal processing process through actual communication system, in the system experiment, the synchronous signal shall be extracted at the receiver end, do not need wiring any more.
5.Equipped with manuals and multimedia teaching courses which can dynamically display the wiring process and the corresponding experiment result
6.The module label , signal process and function blocks shall be clear, I/O interfaces and its function label shall also be very clear, thus can make the student be familiar with each module and its function in the shortest time.
7.For the convenience of upgrading the purchased module in the future, the product shall support “one key “upgrading through SD card, can directly insert the SD card to the main control module, through menu selecting can upgrade the module.
8.Each module shall be equipped with independent multiway power supply switch, the student can carry out independent open and shut off each module according to actual conditions.
9.In order to meet the requirement of the module individual setting and adjusting when the student are innovation researching, the product cannot only be batch setting of the many modules according to the experiment project, but also can support independent adjusting each parameter of each module.
10.Product shall have a very well man-machine interface, for convenience operation, the main control module shall be equipped with color LCD display screen.
11.Standard configuration module: signal source& main control module, voice terminal&user interface module, digital terminal& TDMA module, TDMA and time division switching module, base band transmission encoding and decoding module, carrier synchronous and bit synchronous module, 1310nm optical tranmitting and receiving module, 1550nm optical transmitting and receiving module, optical power meter&error detector module
12.Enriched the knowledge of optical passive components, and equipped with many kinds optical cable and cable stripping off tools which can make the student fully understand the internal structure
13.The traning box itselt can realize programme-controlled exchange telephone system frame.
14.Added telephone dialing function, can finish calling and anwering the whole process state diplsay, also can real time observe the all kinds of singal waveform
15.Equippd with simulation software matched with hardware experiment training box, which can realize the same the function and operation mode with the hardware on the PC, the software integrates TDS1002 oscilloscope function, can observe the experiment waveform, convenient for the school to carry out the theory and practice integration teaching .
