7820C CATV Optical Receiver

200 MHz HFC Return Path

DATASHEET | MARCH 2012

FIBER OPTICS

The 7820C 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 in the 200

MHz HFC return path bandwidth.

The 7820C exhibits excellent distortion performance with values well above

standards over the entire bandwidth and case temperature specifications (5 MHz

– 200 MHz, -40 °C to +85 °C).

Applications

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 2 pA/√Hz.

Video Signal Distribution in HFC and

FTTx nodes

The 7820C Return Path HFC CATV optical receiver can be used in both 1310 nm

and 1550 nm applications being useful at different points of a given network.

Features

5 MHz – 200 MHz Bandwidth Supports

the Return Path CATV Application.

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

Substances in Electrical and Electronic Equipment (RoHS) guidelines

2002/95/EC.

Excellent RF Frequency and Distortion
