China Fiber Indoor Fiber Optical Receiver

We are professional manufacture in CATV line in China, we offer CATV splitter, CATV amplifier, CATV optical receiver, CATV optical transmitter, CATV optical optical switch, EDFA and so on.
CATV optical receiver feature:
1. Forward optical receive part adopts PHILIPS, PHOTON and E-O PIN Optical Receiving IC, import PHILIPS or Motorola low-noisy push-pull amplify module in pre-RF amplify circuit, import PHILIPS or Motorola power double amplify module ( or depends on customers, adopt GaAs).
2. Return optical receive part adopts high-performance FP or DFB laser as optical source, adopts PHILIPS or Motorola low-noise amplifier module as RF amplifier, ensure NPR.
3. Insert Dual-Filter, insert Fix-Equalizer, Fix-Attenuator insert output splitter, eighth-order optical power indication, reasonable testing connector, make more convenient
4. Aluminum waterproof housing, high-capability power switch, anti-thunder system, make sure work properly outdoor.
