This outdoor type receiver is our new high-class 4-way output CATV network optical receiver.This node is design with RFOG circuit which well control the return path laser on and off according to the CM command.And pre-amplifier adopts GaAs MMIC, post-amplifier adopts GaAs module to make the device achieve high performance.It is design as CWDM one fiber design which greatly reduce the cost of network design. Wtih microprocessor control and the digital display the parameters, it is more convinient when testing and debugging. It is the main products to build CATV network.

* High response PIN photoelectric conversion tube.

* With RFOG circuit design to well control the return path laser

* With CWDM one fiber design to reduce the cost of network design

* With optimized circuit design, SMT process production, optimized signal path

* With specialized RF attenuation chip, good RF attenuation,equilibrium linear and with high accuracy.

* GaAs amplifier device, power doubly output, high gain and low distortion.

* Microprocessor control working status, digital display the parameters, convenience and intuitive operation, and stable performance.

* Excellent AGC performance keep output CTB and CSO unchanged when the input optical power range is －9～＋2dBm
