LIGHT TRANSMISSION MONITOR OF AN OPTICAL NETWORK SYSTEM AND A METHOD THEREOF FOR MONITORING OPTICAL TRANSMISSION PERFORMANCE AND THE FAILURE OF PASSIVE OPTICAL NETWORK TRANSMISSION SYSTEM

摘要

PURPOSE: A light transmission monitor of an optical network system and a method thereof for monitoring optical transmission performance of the failure of passive optical network transmission system are provided to measure transmission quality of transceiving optical signal by performing light delivery monitoring of a plurality of WDM-PON systems.;CONSTITUTION: A signal input unit(310) inputs a part of transfer uplink or downlink optical signal. A photoelectric signal converter(340) changes the inputted optical signals to electric signals. A signal analyzer(350) generates analysis information. The analysis information comprises the information about the optical transmission performance or the blocking information.;COPYRIGHT KIPO 2010
