Guangtai 47~1200MHz FTTH CATV Optical Fiber Receiver H1228

Product DescriptionH1228, the operating bandwidth of 47~ 1200MHz, is a low power, high performance, cost-effective triple play, FTTH CATV optical receiver, Whether used in analog television or digital television. Products with high sensitivity optical receiver tube and Huatai special low noise matching circuit. Receiving at high optical power can be adjusted by PAD level, played limiting output, so H1228 within a large dynamic range of the received optical power of +2 dBm ~-21dBm, have excellent characteristics.H1228 for Analog TV, in Pin =-10dBm when, Vo≥ 75.7dBμV, CNR≥ 45.3dB.H1228 for Digital TV, in Pin =-16dBm when, Vo≥ 67.2dBμV, MER≥ 36.1dB.H1228 for Digital TV, in Pin =-20dBm when, Vo≥ 58.8dBμV, MER≥ 30dB.Triple play, fiber to the home, using theH1228 can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.Product Features1. Extra-low noise(3.8% modulate, -10dBm receive, CNR ≥ 45.3dB)2.
