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
l OBI-free, cost effective
l Passive optical distribution for downstream
l 16-way RF combination for upstream
l Support DOCSIS 3.1
l DFB laser for upstream
l LED indicators for optical input and output
l High-sensitivity, low-noise optical receiver
l -20dB external RF test points
l Variable attenuator for all adjustments of receivers output and transmitter input
l 19 inch, 1RU box, compact size
