Huatai H9222LG, 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 H9222LG in the received optical power over a large dynamic range of +2 dBm ~-21dBm, and have excellent properties.
H9222LG for Analog TV, in Pin =-10dBm when, Vo ≥ 83.3dBμV, CNR ≥ 45.7dB.
H9222LG for Digital TV, in Pin =-17dBm when, Vo ≥ 79.0dBμV, MER ≥ 37.1dB.
H9222LG for Digital TV, in Pin =-21dBm when, Vo ≥ 70.3dBμV, MER ≥ 31.1dB.
Digital TV FTTH applications, the H9222LG 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.
