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.
