RFoG1541/RFoG1561
Burst Mode Bi-directional CATV RFoG Optical Node
Original RH9541/RH9561
Product description
RFoG1500 series RFoG ONU ( Optical network unit ) optical node , 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.
RFoG1500 uplink adopts 1550nm wavelength which can fully substitute the traditional HFC networks, saving lots of RF amplifier, thus, it can improve the quality and stability of network operation.
RFoG1500 RFoG ONU uplink channels adopts burst mode, which can largely reduce the Funneling noise at uplink channels and improve stability of network operation.
RFoG1540: 1550nm uplink wavelength, 5~42MHz uplink bandwidth.
RFoG1560: 1550nm uplink wavelength, 5~65MHz uplink bandwidth.
Product features
- Uplink channels adopt burst mode.
- Take use of RF and DOCSIS technique configuration optical distribution network.
- Using single-fiber with bi-direction mode that could reduce the fiber consumption.
- No need of HFC optical node, reduce the cost of network maintenance and operation.
- 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) reduce the funneling noise
- Local feeding or remote feeding can be done through 75Ω coaxial cable
- Aluminum die-casting housing, favorable for heat dispersion
Main application
- 256 RFoG
- PON to substitute HFC
