WDM/TDM HYBRID OPTICAL NETWORK SYSTEM, OLT ADAPTIVE TO PACKET ERROR AND PACKET INTERVAL ADJUSTING METHOD THEREOF

摘要

PURPOSE: a kind of WDM/TDM mixed optical networks system, the packet interval method of adjustment of OLT and its uplink optical signal sent with reducing Packet Error Ratio by adjusting packet interval according to the ONU of Packet Error Ratio. ;CONSTITUTION: optical splitter, in conjunction with the 1st division multiplexing TDM (time) optical signal, from the unit of ONU () (10) optical-fiber network, wherein the optical signal of the first TDM (time) points of multiplexings. First wave length conversion equipment (30) receives TDM signals. Second Waveform converting device (40) receives WDM optical signal and segmentation WDM optical signal is converted into the second WDM optical signal. OLT (optics) (50) the line terminal detects an error grouping. ;The 2011 of copyright KIPO submissions
