SPLITTER MODULE, DETECTION METHOD FOR REMAINING OPTICAL CONNECTOR USING THE SAME, DETECTION METHOD OF NUMBER OF OUTPUT PORTS, AND OPTICAL TRANSMISSION LOSS MEASURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a splitter module for producing time difference in light signal transmission in a plurality of optical fiber transmission lines.

SOLUTION: The splitter module 7 includes: a light splitter 23 for branching a light signal input to an input terminal 29, and outputting the light signal to output terminals 311to 318; output ports 251to 258each in which an insertion opening is formed at one end, an optical connector 33 being to be inserted into the insertion opening; and optical fiber transmission lines 271to 278for optically connecting the respective output terminals 311to 318and the respective output ports 251to 258. The optical fiber transmission lines 271to 278are different in optical path length.
