H9122TG, operating bandwidth of 47 ~ 1050MHz, is a top-level type, ultra low optical CATV receiver, regardless of the aircraft for analog television or digital television, have high reception sensitivity and excellent intermodulation distortion index. Built-in light AGC, a high optical power when receiving, play limiter output, so H9122TG at + 2 ~-24dBm large dynamic range of received optical power, and have excellent characteristics.
For Analog TV, in Pin =-10dBm when, Vo ≥ 82dBμV, CNR ≥ 45dB.
For Digital TV, in Pin =-19dBm when, Vo ≥ 83.2dBμV, MER ≥ 36.5dB.
For Digital TV, in Pin =-24dBm when, Vo ≥72.2dBμV, MER ≥29.9dB.
Digital TV FTTH applications, the H9122TG 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.
