Abstract

PROBLEM TO BE SOLVED: To enable the verification of the fiber cable gauge of an optical fiber by providing a plurality of through holes to transmit out-going light from the optical fiber and a plurality of light shielding parts to shield the out-going light for housing holes housing one ends of a plurality of optical fibers. SOLUTION: This jig 10 for verifying fiber cable gauge is provided with housing holes 15 to house one ends of a plurality of placed optical fibers individually. The housing holes 15 are provided with a plurality of through holes 16 to transmit incident- out-going light from the optical fibers and a plurality of light shielding parts to shield the out-going light. For example, the second one and the fourth one from the top are used as the through holes 16, and blank caps 17 are inserted into the first one and the third one to be the light shielding parts. In the case of verifying the fiber cable gauge of multi-fiber cable optical connector in the state that the first and second optical fibers are misplaced in wiring, when light is passed through the first optical fiber, light which should not be seen, is seen by transmission through the second through hole 16. By this, it is verified that the first optical fiber is misplaced, and fiber cable gauge failure is detected.

The wire number defect is such that light is sequentially incident on each of the optical fibers mounted on the multi-core optical connector one by one, and the position of the light emitted from the end face of the optical fiber exposed at the end of the multi-core optical connector is determined. This is done by visual observation. However, since the arrangement interval of the end faces of the optical fibers exposed at the end of the multi-core optical connector is narrow, it is extremely difficult to check the number of the optical fiber that emits light from the end. The confirmation required a great deal of effort and hindered productivity. The present invention provides a wire number checking jig for a multi-core optical connector which can easily check wire numbers of a plurality of optical fibers mounted on the multi-core optical connector, and a wire number checking method using the jig. With the goal.
