Flooding detection module and the flooding detection manner

摘要

PPROBLEM TO BE SOLVED: To achieve an immersion detection module for detecting immersion without having a mechanical drive part by having easy manufacture. PSOLUTION: The immersion detection module 8 leaks light from a gap 2 during immersion since the gap 2 connected to a vacant hole of a clad part on a bent part applied when performing installment of an optical fiber 1 to the optical fiber 1 having the vacant hole in the clad part or in the vicinity thereof. During immersion, the immersion detection module notices on a point where loss generates on transmission light by allowing light to leak from the gap 2, and easily detects generation of immersion by observing the generation of the loss.
