Abstract: A method and an article made by a method for embedding optical fibers into an organic laminate structure. The optical fiber cabling, along with its cladding, is placed upon a first laminate layer that includes a composite made of silica fillers and a frictionless material such as polytetrafluoroethylene (PTFE). Then a second layer of PTFE material with silica fillers and copper sheeting is placed on top of the PTFE with silica fillers composite. The PTFE material with silica fillers flows about the optical fibers at a temperature approximately fifty degrees above the PTFE with silica fillers material's melting point. This procedure completely encases the optical fibers within an opaque sheath.

Abstract: A self-supporting fiber optic cable includes a messenger section having at least one strength and anti-buckling member enclosed within a jacket and a carrier section enclosed within a jacket that is joined to the jacket of the messenger section by a web. In a preferred embodiment of the present invention, carrier section does not include strength members and the optical fibers are set with a high EFL. The greater EFL accommodates elongation of carrier section without transmission of stress to optical fibers. In addition, the preferably generally cylindrical internal surface of a tube or jacket curves the optical fibers creating EFL, for example, the fibers are guided by the internal surface in a helical path. Resistance to carrier section elongation and contraction can be controlled by varying the length of the web connecting the carrier and messenger sections.

Abstract: A cable termination arrangement is used to terminate cables, such as armored fiber optic cables, to a connecting structure, such as a cable joint or coupling. Strength members, such as aramid rods, extending along the cable are terminated with radial termination members, such as crimping ferrules. The radial termination members extend into a termination cavity within the connecting structure and are spaced substantially equally, for example, using separators. An epoxy or other suitable retaining material encases the radial termination members, strength members, and separators.

Abstract: The present invention relates to a wide-band, low-loss, submarine optical cable excellent in productivity, an optical fiber unit employed in the submarine optical cable, and a method of making the optical fiber unit. The optical fiber unit employed in the submarine optical cable comprises a loose structure in which one or more coated optical fibers are accommodated together with a soft resin in a space formed within a plastic support. In particular, one or more compression members are embedded in the plastic support along the space accommodating the coated optical fibers. The compression members closely in contact with the plastic support prevents the shrinkage of the plastic support from occurring due to temperature changes before forming a cable utilizing the optical fiber unit. Preventing the shrinkage of the plastic support from occurring before forming the cable suppresses the increase in surplus length ratio of the accommodated coated optical fibers, thereby effectively restraining the transmission loss of the submarine optical cable from increasing due to the increase in surplus length ratio.

Abstract: In a fiber optic cable having a plurality of optical ribbons, identifying information about each optical ribbon is conveyed by a series of colored regions of different colors visible on an outer surface of the optical ribbon matrix covering. In preferred embodiments of the present invention, the colored regions are formed in such a way that they do not cause microbending or the like. Preferably, the colored regions are formed during the process of extruding the matrix covering over the fibers, by injecting colored material into the extrusion die.

Abstract: An optical fiber holding structure is used to restrain high fiber count fibers or to provide splice protection in a cable joint. Layers of fibers are inserted between a compliant splint member and a semi-rigid splint member, which are positioned within an outer gripping tube such as a heat shrink tube. Optionally, an internal support can be positioned between the layers of fibers. The assembly is heated causing the heat shrink tube to apply a gripping force to the splint members and fibers supported therebetween. Where more than two layers of fibers are being restrained, internal supports can be positioned between each of the fiber layers. One type of internal support includes a rigid beam coated with a compliant material.
