The present disclosure provides an optical fibre ribbon. The optical fibre ribbon includes a plurality of optical fibres bonded with a matrix material. The matrix material is applied along a longitudinal length of the plurality of optical fibres. Further, the plurality of optical fibres is defined by a geometrical centre and diameter. Further, the plurality of optical fibres has a predefined distance between geometrical centres of any two adjacent optical fibres of the plurality of optical fibres. Moreover, the predefined distance between geometrical centres of any two adjacent optical fibres of the plurality of optical fibres is less than 200 microns. Further, the optical fibre ribbon provides the optical fibre ribbon cable that is flexible and easy to install in space constraint regions and allows ribbons to bend easily at non-preferential axis. Furthermore, the optical fibre ribbon with reduced weight and with high mass fusion splicing capability.

A fiber optic cable terminal proximally terminates a stub cable carrying one or more optical fibers. The stub cable is structurally adapted to be advanced through at least a portion of a conduit by distally pushing a distal end of the stub cable from a location that is proximal to a proximal end of the conduit and without applying any pulling force at any location that is distal to the proximal end of the conduit.

The present invention relates to padded optic fiber ribbons for dry optic fiber cables. The dry padded optic fiber ribbons include a plurality of optic fiber ribbons stacked on top of each other having a cross-sectionally rectangular shape. In addition, the dry padded optic fiber ribbons include a plurality of dry paddings. Each dry padding of the plurality of dry paddings has an inner side and an outer side. Further, the dry padded optic fiber ribbons include at least one tape wrapping around the plurality of dry paddings.

An optical fiber cable includes: a core; a sheath that accommodates the core therein; and a pair of tension members embedded in the sheath. The core includes: a plurality of optical fiber units that each includes a plurality of optical fibers; fibrous fillings that extend in a longitudinal direction in which the plurality of optical fiber units extends; and a wrapping tube that encloses the plurality of optical fiber units and the fibrous fillings. The core is interposed between the pair of tension members.

Two bundle materials are provided on the outer periphery of a plurality of optical fibers. The bundle materials are twisted back while reversing the winding from front to back and vice versa to thus wind the bundle materials around the plurality of optical fibers. That is, the bundle materials are not wound spirally around the plurality of optical fibers. The bundle materials are bonded at a bonding portion where both bundle materials intersect. The bonding portion is provided along a center line of an optical fiber unit. The bundle materials are arranged in ranges which are each approximately 180 and partitioned by the center line.

An optical cable is provided. The optical cable includes an outer cable body jacket and a plurality of optical fiber subunits. The optical fibers within each subunit are stranded relative to each other and are located within a thin subunit jacket. A plurality of unstranded optical fiber subunits are located within the cable jacket.

A flexible optical ribbon and associated method is provided. The ribbon includes a plurality of optical transmission elements and a polymeric ribbon body surrounding the plurality of optical transmission elements. The ribbon body includes a plurality of recesses formed in the ribbon body, and each recess has a depth extending from the first major surface toward the plurality of optical transmission elements and a length extending along the ribbon body between a first recess end and a second recess end. The first recess end is defined by a concave curved surface of the polymeric ribbon body.

A flexible optical ribbon and associated systems and methods of manufacturing are provided. The ribbon includes a plurality of optical transmission elements and an inner layer comprising a cross-linked polymer material and an outer surface. The outer surface of the inner layer includes first areas having first concentrations of uncrosslinked polymer material and second areas having second concentrations of uncrosslinked polymer material. The first concentrations are greater than the second concentrations. The ribbon includes an outer polymer layer having an inner surface interfacing with the outer surface of the inner layer. The outer polymer layer has a higher level of bonding to the inner layer at the first areas than at the second areas due to the ability of the outer polymer material to bond or crosslink with the larger numbers of uncrosslinked polymer material in the first areas.

The present disclosure provides a rollable optical fiber ribbon. The rollable optical fiber ribbon includes a plurality of optical fibers positioned along a longitudinal axis of the rollable optical fiber ribbon. In addition, the rollable optical fiber ribbon includes a matrix material covering the plurality of optical fibers to provide flexibility to the rollable optical fiber ribbon. Further, the rollable optical fiber ribbon includes at least one colour line marking on the rollable optical fiber ribbon along the longitudinal axis of the rollable optical fiber ribbon.

An optical fiber ribbon and a related cable are provided. The ribbon includes a first group of at least one optical fiber and a second group of at least two optical fibers coupled together. The ribbon includes a first hinge coupling the first group to the second group. The hinge allows movement of the first group and the second group of optical fibers relative to each other such that the ribbon is moveable between an aligned position and a collapsed position. The number of optical fibers in the first group is less than the number of optical fibers in second group.
