METHOD AND DEVICE FOR TESTING MULTI-CORE OPTICAL FIBER CABLE FITTED WITH OPTICAL CONNECTOR

WIPO Patent Application WO/1991/019179

A1

A testing method and a device for testing the quality of a multi-core optical fiber cable (11) fitted with an optical connector (12). A preferable testing method is one in which a light transmitting/blocking member (24, 48) which selectively transmits or blocks a beam outputted from the output end of each optical fiber (42) and inputted to a light receiving sensor (21) for every beam emitted from the output ends are provided between the output end of each optical fiber (42) and the sensor (21), the inspection of the arranging order of the respective optical fibers (42) and the measurement of the connection loss are performed simultaneously by causing the beams inputted in and outputted from the optical fibers (42) in a predetermined order to pass in the predetermined order through the transmitting/blocking members (24, 48) and by sensing a beam and the luminous quantity of the beam using the light receiving sensor (21). Thus the test of the multi-core optical fiber cable fitted with an optical connector can be performed efficiently and in a short time.
