Fiber optic connector with protective cable sleeves
First Claim
Patent Images
1. A fiber optic connector for joining the ends of a pair of fiber optic bundles comprising:
- first and second fiber optic cables each containing a fiber optic bundle including a plurality of light transmitting fibers terminating in a planar end surface;
first and second mating connector members containing said first and second cables, respectively;
each said cable including a hollow body substantially surrounding the end of its respective bundle and having one end coplanar with said end surface of said bundle;
each said cable also including a sleeve surrounding its respective hollow body, said sleeve having at one end thereof a flat annular flange extending inwardly over said end of said body providing an optical window for said bundle, said flat annular flange lying in a plane parallel to said planar end surface; and
means in said connector members positioning said cables in axial alignment and causing said flanges at the ends of said cables to abut each other when said connector members are mated whereby said planar end surfaces of said bundles are axially spaced apart.

Abstract
A fiber optic cable for use in a fiber optic connector has a protective sleeve pressed on the end of the fiber optic bundle of the cable with an inwardly extending flange which forms a protective spacer for the end surface of the bundle so that when two cables are mated in abutting relationship the end surfaces of the fiber bundles are spaced apart, preventing end surface bundle scratching which causes excessive light diffusion and results in light reception losses.
