Description
47~862MHz CATV Optical Receiver for FTTH
H9122
Product description
Huatai H9122 product series, CATV Optical Receiver for FTTH ,47~862MHz operate bandwidth, output level Vo=82dBμV (Pin=-2dBm), suitable for FTTH optical fiber access network, which is a low power consumption, high performance, and excellent cost performance RFTV broadcast network ONU(Optical network unit).
Triple play, fiber to the home, using the H9122 can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.
