An optical fiber coupling element in which a short length of optical fiber is placed in a glass sleeve with one end of the fiber projecting from the sleeve. The glass sleeve is collapsed onto the fiber, and a watch jewel is fitted over the fiber end. The other end of the sleeve is flared to facilitate the insertion into it of a second fiber. The sleeve and jewel are sealed into one end of a ferrule.

Optical fiber coupling element

A spiral spring strip for coupling a pair of optical fibers which may be terminated with ferrules. The spring loop diameter is reduced by tension so as to grip the ferrules. Several spirals may be employed to form a multiway connector.

Optical fiber connector

A coupling arrangement for mating electrical or optical connector subassemblies in which opposing coupling members are secured by a bayonet arrangement about their outer perimeters. Resilient (spring) fingers on at least one coupling member engage bayonet key-ways about the opposite member outer surface. The key-way and finger interface at the locked position is along at least one chamfered surface to permit the resilient fingers to deflect radially outwardly and 'ride out' of the locked position to allow connector separation in response to excessive cable tension.

Bayonet connector coupling arrangement

A single optical fiber connector in which a watch X-jewel is employed to align the two fibers to be coupled.
