RFoG Repeater

Query


The Radio Frequency over Glass (RFoG) solution enables cable operators to offer a Fiber-to-the-Home (FTTH) architecture without changes to standard equipment in the headend or home.

With the success of RFoG deployments comes an issue, Optical Beat Interference (OBI), it can be generated at the receiver.

RFoG Repeater is an OBI-free solution, enables multiple MAC domains and high-performance upstream operation in an RFoG environment, full DOCSIS 3.1 channel bonding to be deployed efficiently utilizing all available upstream bandwidth, allows multiple upstream RF channel transmissions and therefore, supports higher subscriber penetrations.


Features

OBI-free, cost effective

Passive optical distribution for downstream

16-way RF combination for upstream

Support DOCSIS 3.1

DFB laser for upstream

LED indicators for optical input and output

High-sensitivity, low-noise optical receiver

-20dB external RF test points

Standard JXP plug-in PADs for all adjustments of receivers output and transmitter input

19 inch, 1RU box, compact size
