Remote Node Identification System for Optical Fiber Using Optical Time Domain Reflectometer and Device for The Same

摘要

The optical path distant node identification system according to an embodiment of the present invention includes an optical path including a plurality of nodes, and an optical time domain reflection meter for transmitting an optical signal for measurement to the optical path and receiving a conveyed signal, the The plurality of nodes carry a first optocoupler branching a part of an optical signal from the optical path and an optical signal branched from the first optocoupler through at least two different paths, thereby providing a path difference between the conveyed optical signals. And a path difference inducing unit for generating a difference in peak height of the conveyed optical signals, wherein at least one of the difference in the path difference and the difference in peak height of the conveyed optical signals is set differently in the plurality of nodes. Has been.
