Abstract

PURPOSE:To make construction simpler and light reflection losses at the connected part less by interposing the connector consisting in forming the opposite faces of sleeves to concave spherical faces and forming an elastic member of the same refractive index as that of a fiber core into a concave spherical face shape. CONSTITUTION:Optical fibers 1, 1' are enclosed and held by sleeves 2, 2' of a cylindrical shape formed by resin such as epoxy, in the central part thereof. Said sleeves are inserted into a cylindrical case 3 from its both ends by way of a contactor 4 whereby the optical axes of both fibers are aligned. The opposite end faces 5, 5' of said sleeves 2, 2' are formed respectively into concave spherical faces, and a connector 4 consisting in using a soft and elastic member having the same refractive index as that of the fiber core, for example, silicone rubber or the like and forming the same into a convex lens shape along the concave spherical face is mounted, by means of an adhesive agent or the like, to either one of the end faces 5, 5' in the central bottom of said concave spherical faces. Thereby, the light reflection losses at the joined part may be decreased considerably.
