Huatai P9428, the operating bandwidth of 47 ~ 862MHz, is a low power, high performance, cost-effective triple play, FTTH CATV optical receiver. Products with high sensitivity optical receiver tube and Huatai special low noise matching circuit..
P9428 for Analog TV, in Pin =-9dBm when, Vo ≥ 79dBμV, CNR ≥ 44dB.
P9428 for Digital TV, in Pin =-16dBm when, Vo ≥ 74dBμV, MER ≥ 34dB.
P9428 for Digital TV, in Pin =-20dBm when, Vo ≥ 66dBμV, MER ≥ 27dB.
Triple play, fiber to the home, using the P9428 can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.
