7820R Optical Receiver

5-200 MHz RFoG Return Path

DATASHEET | MARCH 2012

FIBER OPTICS

The 7820R RFoG return path 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 return path,

and delivers the corresponding RF electrical output.

The 7820R exhibits excellent noise performance with values well above standards

over the entire 200MHz bandwidth and case temperature specifications (-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. The device’s

noise performance is typically less than 0.75pA/√Hz for the 85MHz version and

1pA/√Hz for the 200MHz version.

Video Signal Distribution in RFoG and

FTTx nodes

Video Overlay in Passive Optical

Networks (PON).

The 7820R RFoG return path optical receiver can be used in the optical wavelength

range from 1260nm – 1620nm applications.

Features

5 MHz-200 MHz Bandwidth Supports the

Return Path Application.

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

Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC.
