Abstract: An improved connector is disclosed for interconnecting and terminating bundles of light transmitting fibers in such a manner as to have low light loss at the points of connection. The subject connector is suitable for use in either splicing or terminating individual bundles of light transmitting fibers, each bundle including at least one fiber, as well as for connecting a plurality of light transmitting fiber bundles in a single connector assembly. The subject connector includes an annular crimping ring, an annular cap member, and a profiled ferrule member all of which are slipped over the prepared end of a light transmitting fiber bundle. The end of the bundle is prepared by stripping the exterior layer therefrom to expose the light transmitting fibers. In the case of the bundle including a plurality of fibers, it may be preferable to also pretreat the bundle by applying a potting compound to the fibers to form them into a cohesive unit.
