Title: Water immersion detection fiber
Inventor: AKASAKA NOBUHIRO
IPC: G01M3/38
Filed: 1989-02-06
Abstract: PURPOSE:To easily detect water immersion with simple constitution by stranding an optical fiber and a wire body made of a material which shrinks at the time of contacting water and winding a water-soluble film around their outer periphery. CONSTITUTION:The water immersion detection fiber 20 is formed by stranding the optical fiber and wire body 22 made of a shrinkable fiber with low tension and the water-soluble film 23 is wound covering their outer periphery. The water immersion detection fiber 20 is put in a cable made of, for example, synthetic resin to constitute an optical cable. Consequently, if the cable flaws to cause water to enter the cable, the shrinkable wire body 22 shrinks at the water immersion position to detect an increase in transmission loss from the microbending of the optical fiber 21, and back scattered light is measured to detect the water immersion position.
