Node Quang 870MHz Prevail WR1002JL

WR1002JL new high-grade tow-output CATV network optical receiver. The pre-amplifier adopts full-GaAs MMIC, post-amplifier adopts GaAs module. Optimized circuit design coupled with rich 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 Characteristics

  • High response PIN photoelectric conversion tube.
  • Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.
  • Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
  • GaAs amplifier device, power doubler output, with high gain and low distortion.
  • Single chip Microcomputer ( SCM ) control equipment working, LCD display the parameters, convenience and intuitive operation, and stable performance.
  • Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.
  • Reserved data commubication interface, can connect with the Ethernet transponder, access to network management system.
  • Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
