Abstract
An optical measurement system is disclosed which enables rapid and repeatable measurement of insertion and return loss of each fiber in sequence of a multi-fiber connector 15 connected to an optical fiber ribbon 16 to be obtained without disturbing either the light source 17, 18 or detector components 19, 20 of the system. The system comprises a multi-channel optical switch 1 for connection to a light source 17, 18; 1.times.2 bi-directional splitters 2 each of which is optically coupled between one of the channels of the multi-channel optical switch and one fiber of a master multi-fiber connector 3, of which the geometry is known, for mating with a multi-fiber connector to be tested and, for connection to at least one detector for monitoring and recording the power reflected at the interface between a pair of optical fibers interconnected by the mating of the master multi-fiber connector and the multi-fiber connector under test, and a splitter 11 to which each of the bi-directional splitters 2 is also optically coupled.
