The 7820A CATV Optical Receiver is a single-mode fiber pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification.

The device receives optical analog and/or digital signals for a range of video broadcast options, and delivers the corresponding RF electrical output. The wide bandwidth supports the delivery of up to 110 CATV analog signals or a combination of analog and digital channels (80/30 for example), including HDTV broadcast.

The 7820A exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications (40 MHz – 1002 MHz, -30 °C to +85 °C).
