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

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the
operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect
device reliability.
