OPRG-300C RFOG FTTH Optical Receiver offers the operators competitive advantage and enormous flexibility over the traditional HFC architectures --- avail enough the existing RF and DOCSIS technology to deploy a fiber optic distribution network. OPRG-300C operates over a standard Passive Optical Network (PON) ODN architectures using a standard HFC optical wavelength, connect to cable modems, televisions and set-top boxes through the existing coaxial cable, no need the neighboring HFC nodes and the annual testing and maintenance. OPRG-300C allows PON, RFoG and mixed PON network to extend the bi-directional and interactive RF business through the passive optic distribution network, it could be used at the same optic cable which PON access to support the voice, video and data business. OPRG-300C provides bi-directional services over extended RF frequencies (up to 1.1GHz) while being agnostic to head-end equipment, customer equipment, and compatible with today’s operating processes



(1) For FTTH network

(2) Using the low noise pHEMT GaAs FET as the first RF amplify module, fit to low optic power input.

(3) Support the universal HFC set-top box, cable modem and head-end equipment

(4) Transparent return path capability (protocol and modulation format agnostic)

(5) Optical AGC function ( reach the positive RF level

(6) Reduce the convergence noise

(7) Local or remote power supply

(8) Die-casting aluminum housing, excellent heat dissipation performance

(9) It is compatible with DAVIC and DOCSIS
