摘要： A pair of guide holes for guide pin insertion and one or a plurality of optical fiber positioning holes extending inwardly from the front end surface are formed in a connector ferrule of an optical connector. A chamfer is formed on the opening edge portion of the guide hole of the connector ferrule on the front end surface side thereof. The opening diameter R of the guide hole at the front end surface is preferably 1.0 to 1.5 mm when the front end surface is slant polished at an angle of 8 degrees. Furthermore, the chamfering angle θ of the chamfer is preferably 90 to 150 degrees. Moreover, the average particle size of the filler contained in the connector ferrule is no more than 20 μm. As a result, the surface of the chamfer is comparatively smooth.

摘要： An optical transmission component and a method of making the same in which one or a plurality of optical fibers 1 are fixed to a main body 3 of the optical transmission component with one end face of each optical fiber being exposed, and thus exposed end face is used as a connecting end face to be optically connected to another optical transmission component. The coating 1b of each optical fiber 1 is removed, so as to expose a predetermined length of an optical fiber 1a. An end face 1c of thus exposed optical fiber is processed by spark discharge processing in a short period of time, such that at least the front end of a core portion projects from the front end of its cladding portion. Thus processed optical fiber 1 is inserted into the main body and fixed thereto with an adhesive 5, while a predetermined pressure is being added along the optical axis of each optical fiber 1 from the end face 1c side.
