ABSTRACT:
An apparatus of the present invention is an apparatus for housing a splice reinforcing portion of optical fiber, which comprises (a) a first holding member for holding a splice reinforcing portion for reinforcing a splice between a first optical fiber and a second optical fiber optically connected to the first optical fiber and constituting a light transmission line together with the first optical fiber, and (b) a first photosensor disposed on a side surface of the splice reinforcing portion, receiving leaking light from the splice reinforcing portion, and fixed to the first holding member. Then the apparatus detects the leaking light from the splice reinforcing portion always existing at a splicing site of optical fiber, thereby enabling to perform stable communication free of influence of a covering of optical fiber, enabling to perform long-distance communication, including less risk of damage of optical fiber, disconnection, interruption of operation, and so on, and thus performing optical communication without a need to cut the optical fiber at the splicing site.
