1 GHz

DATASHEET | MARCH 2012

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).

Applications

Video Signal Distribution in HFC and

FTTx nodes

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.

Video Overlay in Passive Optical

Networks (PON).

Features

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.

5 Wide 40 MHz – 1002 MHz Bandwidth

Supports as Many as 110 CATV Analog

Channels or a Combination of Analog

and Digital Channels Including HDTV

Broadcast.

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.

Excellent RF Frequency and Distortion

Characteristics for High Linearity.

Low Noise (4.5 pA/√Hz typ.) Low Power

Dissipation (0.75 W max.) as well as

High RF Output.
