FTTH Fiber Optic Node with WDM for Both XPON and Digital TV System
-------------------------------------
1.0 PRODUCT DESCRIPTION
SR2020AW, the operating bandwidth of 47~1000MHz, 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 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.
For Analog TV, in Pin =-10dBm when, Vo≥ 75.7dBμV, CNR≥ 45.3dB.
For Digital TV, in Pin =-16dBm when, Vo≥ 67.2dBμV, MER≥ 36.1dB.
For Digital TV, in Pin =-20dBm when, Vo≥ 58.8dBμV, MER≥ 30dB.
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.
