AUTOMATIC OPTICAL LINE QUALITY MEASURING SYSTEM BY MONITORING/CONTROLLING FTTH PON CAPABLE OF EXTENDING AN OPERATION MANAGEMENT TECHNIQUE OF AN OPTICAL LINE

摘要

PURPOSE: An automatic optical line quality measuring system by monitoring/controlling FTTH(Fiber To The Home) PON(Passive Optical Network) is provided to perform efficient maintenance of an optical line through continuous management of BER(Bit Error Rate) data.;CONSTITUTION: An OLT(Optical Line Terminal)(110) generates a test pattern signal. The OLT transmits the test pattern signal and a loopback control command signal. An RTU(Remote Test Unit)(114) receives the test pattern signal and the loopback control command signal from the OLT. The RTU transmits a loopback signal to the OLT through a loopback operation according to the loopback control command signal.;COPYRIGHT KIPO 2012
