摘要： An optical fiber cable includes a jacket and a plurality of stranded core subunits, each core subunit comprising a flexible sheath and a plurality of ribbons arranged in a ribbon group, wherein each ribbon of the plurality of ribbons comprises a plurality of connected fibers such that 50-70% of the cross-sectional area inside the sheath is occupied by the connected fibers. The flexible sheath may be an extruded PVC material that conforms to the shape of the ribbon stack and keeps all of the ribbons acting as a unitary body during bending.

摘要： Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an inner surface and an outer surface in which the inner surface defines a central bore along a longitudinal axis of the optical fiber cable and the outer surface defines the outermost extent of the cable. The optical fiber cable also includes at least one access feature disposed in the cable jacket between the inner surface and the outer surface. Further included are a first plurality of optical fiber bundles. Each optical fiber bundle includes a second plurality of optical fiber ribbons that has a third plurality of optical fibers arranged in a planar configuration. The optical fiber cable bends uniformly in all directions transverse to the longitudinal axis of the optical fiber cable.

摘要： Embodiments of the disclosure relate to an optical fiber cable having at least one optical fiber, a cable jacket, and a foam layer. The cable jacket has an inner surface and an outer surface. The outer surface is an outermost surface of the optical fiber cable, and the inner surface is disposed around the at least one optical fiber. The foam layer is disposed between the at least one optical fiber and the cable jacket. The foam layer includes a polymer component having from 30% to 100% by weight of a polyolefin elastomer (POE) or thermoplastic elastomer (TPE) and from 0% to 70% by weight of low density polyethylene (LDPE). The foam layer has a closed-cell morphology having pores with an average effective circle diameter of 10 μm to 500 μm. Further, the expansion ratio of the foam layer is at least 50%.
