Forward-Path Receiver (fRCVR)

Data Sheet

The Optilab fRCVR forward-path high performance receiver is a highly linear optical to electrical converter for use in HFC, RFoG, PON, and deep fiber applications.

Product Overview

The Optilab fRCVR forward-path high performance receiver is a highly linear optical to electrical converter for use in HFC, RFoG, PON, and deep fiber applications. The fRCVR uses a high gain, low distortion receiver module and low noise RF circuit to deliver 50 dB of CNR, while maintaining optimal CSO and CTB distortion specifications. It features Automatic Gain Control (AGC) for automatic adjustment of the optical input level, and Manual Gain Control (MGC) for optimal RF gain level control. It supports up to 75 NTSC analog channels, and because it is designed to be digitally ready, it can be loaded with 60 additional QAM modulated digital channels. The fRCVR model provides a standard RF output level of 40 dBmV or an optional higher RF output level or 52 dBmV. Contact Optilab for more information.
