Fiber node CATV Optical Receiver

1.0 PRODUCT DESCRIPTION of Fiber node CATV Optical Receiver
SR2020AW, the operating bandwidth of 47~1000MHz, is a low power, high performance, cost-effective triple play, Fiber node CATV optical receiver, Whether used in analog television or digital television. Products with high sensitivity optical receiver tube and special low noise matching circuit. Receiving at high optical power can be adjusted by PAD level, played limiting output, so SR2020AW within a large dynamic range of the received optical power of +2 dBm ~-21dBm, have excellent characteristics.
Triple play, fiber to the home, using the SR2020AW can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.
