| Description
OPR-2104G is our latest 1GHz high-class CATV network optical receiver. (860MHz can be specified also).
This equipment adopts full-GaAs MMIC amplify device. Optimized circuit design makes the equipment achieve good performance indexes. Microprocessor control, digital display the parameters, the engineering debug is especially easy. It is the main equipment to build the CATV network.
Features
1) High response PIN photoelectric conversion tube.
3) Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
4) GaAs amplifier device, power double output, high gain and low distortion.
5) Microprocessor control working status, digital display the parameters, convenience and intuitive operation, and stable performance.
6) Excellent AGC performance, when the input optical power range is -8～+2dBm, the output level keeps stable, CTB and CSO basically unchanged.
7) Configure Chinese standard network management responder, easy access to the network management system.
