Document Type and Number:
WIPO Patent Application WO/2024/095556
Kind Code:
A1
Abstract:
Provided is a fiber retention structure that can suppress production of heat by light not coupled to an optical fiber. A fiber retention structure 30 comprises: an optical fiber 20 that includes a front end 21, a first fixing part 22 that is positioned behind the front end 21, and an intermediate part 23 that is positioned between the front end 21 and the first fixing part 22; a ferrule 40 that has formed therein a fiber retention hole 41 that retains the first fixing part 22 of the optical fiber 20; an adhesive material 60 that fixes the first fixing part 22 of the optical fiber 20 in the fiber retention hole 41 of the ferrule 40; and a protection member 50 that covers the ferrule 40. The protection member 50 includes: a support part 51 that covers the circumference of the ferrule 40; and a shielding part 52 that covers a front surface 40A of the ferrule 40 and has formed therein a fiber insertion hole 53 into which the intermediate part 23 of the optical fiber 20 is inserted.
