OPTICAL FIBER ASSEMBLY

摘要

An optical fiber assembly of the present invention is configured such that an optical fiber fixing section (i) is fixed to an SUS tube and (ii) sandwiches an optical fiber between a first member and a second member at an end part of the SUS tube, so that the optical fiber is fixed while being spaced from the SUS tube. This makes it possible to provide an optical fiber assembly having a structure that prevents an optical fiber from coming into contact with an edge part of a metal tube on the premise that the optical fiber is covered with the metal tube.

主权项

1. An optical fiber assembly comprising:
a metal tube which covers an optical fiber; and an optical fiber fixing section which is fixed to an end part of the metal tube and which fixes the optical fiber, the optical fiber fixing section including two members having respective optical fiber sandwiching surfaces between which part of the optical fiber is sandwiched and fixed when the two members are combined together, the part of the optical fiber protruding from the end part of the metal tube, at least one of the two members having a cushion layer on its optical fiber sandwiching surface, the two members sandwiching the optical fiber while stress applied to the optical fiber is distributed by the cushion layer, the optical fiber fixing section having a groove into which the end part of the metal tube is inserted when the two members are combined together, the two members forming a fixing part for fixing the optical fiber, part of which fixing part protrudes out into the metal tube when the metal tube is inserted into the groove, and the optical fiber fixing section being fixed to the metal tube while the metal tube is inserted into the groove.
