Leistungsüberwachung einer optischen Übertragungsstrecke durch OTDM mit Laser für Datenübertragung/-empfang

摘要

The invention relates to an optical fiber communications transceiver module (OTM) comprising transmitting (Tx) and receiveing (Rx) means for data transmission and reception to and from a remote location transceiver module, wherein the transceiver module (OTM) further comprises Optical Time Domain Reflectometry measurement means (OTDRM). An optical coupler (OC) is connected to said transmitting and receiving means so that part of the signal power reflected to the transmitting output port (TP) is directed to the receiving means input port (RP) and further analysed by the Optical Time Domain Reflectometry measurement means (OTDRM) of the transceiver module (OTM).
