China 1GHz Field 4way Output Optical Receiver with AGC Wr1004DJ

Product Description

Product Description

. Performance Characteristics

WR1004DJ is our new high-class 4-way output CATV network optical receiver. The pre-amplifier adopts all-GaAs MMIC, post-amplifier adopts GaAs module. Optimized circuit design coordinate with our 10 years design experience, the device achieve high performance index. Microprocessor control, digital display the parameters that make the engineering debug very convenience. It is the main products to build CATV network.

n High response PIN photoelectric conversion tube.

n Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.

n Specialized RF attenuation chip, good RF attenuation and equilibrium linear, high accuracy.

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

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

n Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.

n Reserved data communication interface, it is convenient to connect with network management transponder and access to network management system.

n Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
