CNOR300-S4 outdoor optical workstation is two-way optical joint equipment that based on several years research experience of CATV HFC fiber transmitting equipment, specifically developed for the HFC structure two-way metropolitan area broadband network. When designed the product, we have fully considered the FTTC (fiber to the service area) network topology, the engineering technical problems of CATV two-way return path noise, and the high reliability network security transmission requirement of modern CATV business; optimize the internal circuit structure, and built a perfect states monitoring circuit. Prepare the network management interface which compatible with the standards SNMP standard, by the network management transponder can achieve in the remote network management monitor, it becomes the first choice equipment for constructing the high-quality two-way HFC metropolitan area broadband network.

• Full CPU control the machine work, LCD displays the parameters, such as the input/output level. Variable control operation is convenient and intuitive, and performance is stable.
• Reduce a large number of optional accessories.
• Excellent AGC characteristic, when the input optical power range is -9~+2dBm, the output level, CTB and CSO basically unchanged.
• Two-channel optical signal receiver backup each other, can set automatic switching condition arbitrarily, also can be set to manual switching.
• Optimizing circuit design, SMT production process, optimizing the whole signal path, made the photo-electronic signal transmit more stable, RF linear index higher.
• Professional RF electrical adjustable attenuation chip, RF electrical adjustable equilibrium circuit, good linearity, high precision.
• GaAs amplifier device, power double output, high gain and low distortion.
• The return path adopts professional RF electrical adjustable attenuation chip instead of the three-state switch.
• Reserved the data communication interface, can connect the Ⅱ network management responder, access to the network management system, the variables can be remote controlled by the network management.
