MODULAR APPARATUS FOR OPTICAL COMMUNICATION, CAPABLE OF KNOWING THE DEFECTS OF OPTICAL SIGNAL TRANSMISSION BETWEEN OLT AND ONU

摘要

PURPOSE: A modular apparatus for optical communication is provided to receive the optical signal branched in the light splitter of OLT(Optical Line Terminator).;CONSTITUTION: A light source unit(10) generates and transmits the downward optical signal. A light receiver(30) receives an upward optical signal from an ONU. A reflective beam receiving unit(20) receives the reflection light reflected due to the combination of a spot between the ONU and OLT. A light splitter(100) branches the reflection light. The light splitter transmits the branched reflection light in the reflection light receiver.;COPYRIGHT KIPO 2011
