Abstract: The present invention relates to methods of connecting optical fibers. In a first aspect, the method proceeds by using a ferrule device having a passage adapted to apply radial pressure to optically align and hold in position opposed fiber ends, and fusing said fiber ends held by said ferrule device. In another aspect, the method of the present invention uses a ferrule device to optically align without mechanized adjustment and hold in position opposed fiber ends with a gap where said fiber ends meet, where the fibers have a temperature of fusion that is higher than a melting temperature of said ferrule device. The method then transmits radiation directly onto said fiber ends without significant direct transmission onto said ferrule device to generate heat in said fiber ends and fuse said fiber ends held by said ferrule device.

Abstract: There is provided a mechanical connector for mechanically connecting and optically coupling two optical fiber ends, the connector comprising a longitudinal body, and a fiber conduit in the body for holding the two fiber ends and confining the fibers to be in end to end alignment in the conduit with sufficient inward radial pressure exerted from the conduit on each one of the fiber ends to ensure centering within the fiber conduit to provide the optical coupling without risking damage to a silica core of the fiber ends. The connector is adapted to controllably release the pressure on the fibers to allow for insertion of the fibers in the conduit, and the connector holds the fiber ends in the optical coupling without adhesive. There is further provided a method for mechanically connecting and optically coupling two optical fiber ends.

Abstract: The present solution relates to a system and method of an optical connector assembly for interconnecting two optical fibers. The optical connector assembly has a splice with a fiber conduit for holding bare ends of the two optical fibers together. Additionally, the optical connector has two corresponding ferrules. The two corresponding ferrules are for securing optical fibers and for aligning the bare end of an optical fiber into the splice without catching an edge. The method includes compressing along the longitudinal axis a first ferrule against the splice to force a guiding member of the first ferrule into a first aperture of the splice, thus opening a conduit of the splice at the first aperture. Once the optic fiber is inserted, the method includes releasing the compression along the longitudinal axis of the first ferrule against the splice to allow the splice to apply radial retention forces on fibers. A sheath to form a connector body of the optical connector assembly interconnects the ferrules.

Abstract: Shaped articles of polybut-1-ene are made by preheating a polymer blank in the crystalline form II at a temperature between 20.degree. and 90.degree. C. The preheated blank is then press-forged under a pressure between 8 and 100 kgf/mm.sup.2 for a period of 1-40 seconds. During the shaping operation, the polymer is converted into the crystalline form I. Polybut-1-ene shaped articles are formed that have a melting peak, determined by differential thermal analysis, at 119.degree. C.
