Huatai H9122, the operating bandwidth of 47~862MHz, Products with high sensitivity optical receiver tube and Huatai special low noise matching circuit,Whether used in analog television or digital television, have high reception sensitivity and excellent intermodulation distortion index. is a low power, high performance, cost-effective triple play, FTTH CATV optical receiver.
H9122 for Analog TV, in Pin =-10dBm when, Vo ≥ 69dBμV, CNR ≥ 45dB.
H9122 for Digital TV, in Pin =-15dBm when, Vo ≥ 62.7dBμV, MER ≥ 36.8dB.
H9122 for Digital TV, in Pin =-20dBm when, Vo ≥ 53.1dBμV, MER ≥ 29.4dB.
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.
