ABSTRACT:
An optical fiber assembly is disclosed, which permits reduction of light reflection, suppression of reflected return light and reduction of connection loss and also facilitates its manufacture. The optical fiber assembly 10 comprises an optical fiber 18 and a ferrule 12 with an end taper and mounted on an end portion of the optical fiber. The end face of the optical fiber 18 and the end face of the ferrule 12 are constituted by a convex spherical surface S1 with the center P0 thereof at a position spaced apart from the center line L0 of the optical fiber 18. The radial line L1 passing through the center P1 of the optical fiber and the center P0 makes an angle .theta.' of 6 to 12 degrees with respect to the center line L0, the radius of curvature is 50 to 70 mm, and the symmetricity angle .DELTA..theta. is 0.1 degree or less.
