COMMUNICATION METHOD, APPARATUS AND SYSTEM FOR HFC NETWORK

摘要

Embodiments of the present invention relate to the technical field of communications. Provided are a communication method, an apparatus and a system for an HFC network. The method is applied on the HFC network comprising an OLT and multiple CMCs. The OLT is connected to the multiple CMCs. The CMCs are connected to terminals. The method comprises: the OLT setting a working wavelength corresponding to each CMC, wherein the working wavelength corresponding to each CMC is different from each other; when the OLT sends information to the CMCs, the OLT converting an electrical signal sent to each CMC into a light wave of a corresponding working wavelength, and sending each light wave to a corresponding CMC; when the OLT receives information sent by the CMCs, the OLT receiving a light wave of a corresponding working wavelength sent by each CMC, and converting each received light wave into an electrical signal for processing. According to the present invention, user bandwidth under HFC network architecture is increased.
