 Product description 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.
H9122TG optical port mode with following three types optional:
