Abstract
A terminus for an end portion of an optical fiber has a ferrule with a relatively large passageway extending from an open end to a cylindrical endwall portion, the latter having an opening only slightly larger than fiber glass core with cladding diameter. An optical fiber to be terminated has an end portion stripped of buffer coating and located in the ferrule with the bare glass portion in the smaller opening. A first epoxy secures the fiber within the ferrule. With the fiber end faced-off and polished, the flat face of a plano-convex lens is secured to the ferrule endwall and fiber end by a second epoxy having optical characteristics closely watching those of the lens and fiber. A cylindrical hood fits over the lens and ferrule end. A pair of such terminations are slid into opposite ends of an alignment tube positioning for optical signal transmission.
