Hollow optical fiber unit for optical fiber sensor with hexagonal head and threaded shaft

摘要

An optical fiber unit enables secure grasping of an optical fiber sensor via a jig while avoiding damage to an optical fiber cable. The optical fiber unit for the optical fiber sensor includes an optical fiber cable, a shaft, and a head. The shaft includes a peripheral surface having a male thread, and a through-hole for an inserted optical fiber cable. The head is shaped in a hexagonal prism including six sides and a bottom. The shaft is connected to the bottom of the head. The optical fiber cable extends the head, and extends out of the head in a direction substantially parallel to two parallel sides of the six sides from at least one of the six sides excluding the two parallel sides.

1. An optical fiber unit for an optical fiber sensor, the optical fiber unit comprising:
a head shaped as a hexagonal prism including six sides and a bottom; an optical fiber cable extending inside the head, and extending out of the head in a direction substantially parallel to two parallel sides of the six sides from at least one of the six sides excluding the two parallel sides; and a shaft connected to the bottom of the head, the shaft including a peripheral surface having a male thread, and a through-hole in which the optical fiber cable is inserted.
