WDM-TDM HYBRIDE OPTICAL NETWORK AND SELF DEFECTION METHOD OF OPTICAL CHANNEL PROBLEM THEREOF

摘要

The present invention is a time division multiplexing passive optical network (TDM-PON, time division multiplexing-passive optical network) the wavelength division multiplexing (WDM, wavelength division multiplexing) techniques combined with WDM-TDM hybrid optical network in OLT and WDM-TDM conversion device to a technique for interconnecting the self-test channel failure between each WDM optical transceivers (TRx). ; Such an optical network is a WDM-TDM compound of the present invention, the OLT including M number of optical transceiver 1WDM generating a WDM downstream optical signal (optical line terminal); And a WDM-TDM conversion device including a TDM optical transceiver for converting the first 2WDM optical transceiver and the downstream electrical signal for converting the downstream WDM optical signal to the downstream electric signal to a downstream TDM optical signal, generates a random pattern and this claim 2WDM WDM-TDM conversion device control unit using the optical transceiver is transmitted to the optical transceiver 1WDM the OLT; And wherein the 1WDM and checks the light The pattern transmitted through the transceiver including the OLT control unit that the pattern is transferred to the 2WDM optical transceiver normally when it again, the WDM-TDM conversion device control unit is the first 1WDM optical transceiver If the returned pattern to claim 2WDM optical transceiver to be inflated by this to determine the transmission device of the receiver of the optical transceiver or the 1WDM 2WDM disorder characterized by an optical transceiver configuration. ; Complex, Passive Optical Network, PON, WDM, TDM, hybrid
