Overview
MXT-OR-100 series RFOG ONU make full use of existing RF and DOCSIS technology to configure optical distribution network, to provide competitive advantage and great flexibility.
MXT-OR-100 series RFOG ONU, adopts Passive Optical distribution Network (PON) to realize bi-directional, interactive RF business. In FTTH network, it serves to transmission layer of RF video, DAVIC, DOCSIS, extending the optical network to home or building without the need of adjacent HFC optical node. saving lots of RF amplifier, thus, it can improve the quality and stability of network operation.
Features
● Take use of RF and DOCSIS technique configuration optical distribution network.
● Support the universal HFC STB, CM and Head-end equipment.
● Transparent return path channel (no limitation on protocol and modulation mode).
● Optical AGC function (reach the proper RF level)
● Uplink channels adopts burst mode, reduce the funneling noise.
● Local feeding or remote feeding can be done through 75Ω coaxial cable
● Aluminum die-casting housing, favorable for heat dispersion
● Compatible DAVIC DOCSIS standard
