FIBER OPTICS

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).

Moreover, the proprietary impedance-match circuitry between the photodetector

and RF amplification stages resolves a number of OEM design obstacles with

very low noise performance value, typically less than 4.5 pA/√Hz.

The 7820A CATV optical receiver can be used in both 1310 nm and 1550 nm

applications being useful at different points of a given network.

The 7820A is compliant with all criteria of the Restriction of the Use of Hazardous

Substances in Electrical and Electronic Equipment (RoHS) guidelines

2002/95/EC.
