CORE ADJUSTMENT DEVICE AND CORE ADJUSTMENT METHOD FOR MULTIPLE CORE OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To precisely perform core adjustment and connect multiple core optical fiber to an optical component having a plurality of optical waveguides.SOLUTION: Multiple core optical fiber 30 is opposed to a fiber connection part 42 of an optical component 40 and made to rotate about a central axis C1. When a core 31c for a monitor faces a reflection part 43, an amount of reflected light L2 from the reflection part 43 is increased and detected. Thus, core adjustment of the multiple core optical fiber 30 is performed in a rotation direction about the central axis C1.
