 Product description Huatai H9122LG, operating bandwidth of 47~ 862MHz, is a suitable digital television FTTH applications, ultra-low optical receiver, Whether the machine is used analog television or digital television, have high reception sensitivity and excellent intermodulation distortion index.. Due to the built-in optical AGC, at high optical power receiver, played limiting output, so H9122LG in the received optical power over a large dynamic range of +2 dBm ~-21dBm, and have excellent properties.
H9122LG for Analog TV, in Pin =-10dBm when, Vo ≥ 82dBμV, CNR ≥ 45dB.
H9122LG for Digital TV, in Pin =-15dBm when, Vo ≥ 83.4dBμV, MER ≥ 36.7dB.
H9122LG for Digital TV, in Pin =-20dBm when, Vo ≥ 73.2dBμV, MER ≥ 29.2dB.
Digital TV FTTH applications, the H9122LG can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network. Suitable for rural power digital TV, FTTH, triple play of wide application.
