METHOD, APPARATUS AND SYSTEM FOR PROCESSING SIGNAL OF PON NETWORK

摘要

A method for processing signal in Passive Optical Network (PON) network with multiple uplink channels is provided in the embodiments of the present invention, which characterized in that the method includes: Optical Line Terminal (OLT) generates a corresponding relationship table 2 of all the Optical Network Units (ONU), the downlink channels and the uplink channels; when received the uplink data from the ONUs, the OLT determines the corresponding uplink channel according to the identity OUN-ID of the ONU for transmitting the data, the downlink channel identity DS-CID corresponding to said ONU-ID, or the uplink channel identity US-CID corresponding to said ONU-ID, wherein the ONU-ID, the DS-CID and the US-CID are included in the uplink data, then forwards the uplink data to the corresponding processing module for process through said uplink channel. An OLT and a system for processing the signal are also provided in the embodiments of the present invention. With the embodiments of the present invention, the OLT can identify the uplink data transmitted by ONU and forward it correctly to the corresponding processing module for process, on the basis of the original network without change on system programming, not only the compatibility is good, but also the cost effect is obvious.
