OPR-1002JL II (8602JLII) 2 ways Bi-directional Optical Receiver(RFOG mode optional)
   Content
Description
OPR-1002JLII/OPR-8602JLII is our latest high-grade two-output CATV network optical receiver. The pre-amplifier adopts full-GaAs MMIC, post-amplifier adopts GaAs module. Optimized circuit design coupled with our 10 years professional design experience, make 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.
 
Performance feature
(1) High response PIN photoelectric conversion tube.
(2) Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission smoother.
(3) Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
(4) GaAs amplifier device, power double output, with high gain and low distortion.
(5) Single Chip Microcomputer (SCM) control equipment working, LCD display the parameters, convenience and intuitive operation, and stable performance.
(6) Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.
(7) Reserved data communication interface, can connect with class II network management responder, access to network management system.
(8) Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
