 Optical Receiver
  1. Because of the advanced AGC technology, the output level,CTB and CSO all basically remain unchanged when input optical power keeps in the range of -9~+2dBm;
  2. Downward working frequency extends to 1 GHz. RF amplification part adopts gallium arsenide chip with high performance and low power- consumption. The highest output level can reach 106 dbµv;
  3. We use professional electrically controlled circuit to balance and attenuate, which make control more accurate and operate more convenient;
  4. National-class II built-in network-managing transponder supports remote network management (optional);
  5. Compact structure and easy installation make it be the first choice for FTTB CATV network;
  6. High reliable and low power-consumption build-in power. External power is optional.
