 Product description Huatai H9122L, operating bandwidth of 47 ~ 862MHz, is a suitable digital television FTTH applications, ultra-low optical receiver, Whether used in analog television or digital television. Receiving at high optical power can be adjusted by PAD level, played limiting output, so H9122L within a large dynamic range of the received optical power of +2 dBm ~-20dBm, have excellent characteristics.
H9122L for Analog TV, in Pin =-10dBm when, Vo ≥ 86dBμV, CNR ≥ 45dB.
H9122L for Digital TV, in Pin =-15dBm when, Vo ≥ 84.1dBμV, MER ≥ 36.7dB.
H9122L for Digital TV, in Pin =-20dBm when, Vo ≥ 74.8dBμV, MER ≥ 29.6dB.
Digital TV FTTH applications, the H9122L 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.
H9122L optical port mode of the following three selection:
