Abstract: Each of a pair of members has a mating surface extending from one edge to another. When they are mated together, with optical fibers, they act as a housing. At least one member includes formed grooves on its mating surface, extending from one edge to another thereof. Each groove from one edge of the mating surface to a point medial to the one edge and the other edge is formed to at least partially hold an unjacketed optical fiber therein. Each groove from such point to the other edge is formed to at least partially hold a jacketed optical fiber therein. Each groove in at least one of the members can be uniformly formed from the one edge of the mating surface to the respective point, and can be uniformly formed from the respective point to the other edge of the mating surface. Each groove can change from one uniform formation to a different uniform formation at the respective point.

Abstract: A multiple waveguide cable connector assembly is disclosed for coupling the opposing pluralities of protectively-jacketed optical fiber waveguides contained within a pair of multifiber cables.Each of the two connectors forming the connector assembly contains a plurality of axially extending fiber-guiding channels sized to freely accommodate respective fibers, and a like plurality of transversely displaceable finger-like elements extending inwardly from the outer connector periphery into respective channels. The finger-like elements securely engage the protectively jacketed fibers against the channel walls when transversely displaced.One of the connectors projectingly holds the bared fiber tips from one cable in a predetermined pattern at its mating end. The other connector internally holds the bared fiber tips of the second cable in an abuttment region, and freely accommodates the projecting fiber tips from the first connector upon mating therewith.

Abstract: A device for coupling a pair of optical fibers is disclosed comprising a resiliently compressible body for holding a pair of opposing protectively jacketed fibers in end-to-end abutment within an oversized bore. The body is symmetrically compressed about its central portion to reduce the bore cross-section to a fiber-engaging dimension around the bare fiber tips thereby securely aligning the fibers. Similarly, the body is compressed about its end portions to decrease the bore cross-section to a jacket-clamping dimension whereby stresses in the spliced region are distributed along the fiber jacket.
