example

[0088] According to aspects of the present disclosure, in addition to or in place of the encapsulation element 30, small particles (ie, about 1 μm) may be introduced into the interior of the sheath 12 and or into the interior of the encapsulation element 30 to reduce the core unit 16 movement with the sheath. These particles may be selected from, but not limited to, the following examples: graphite, ultra-high molecular weight beads, silicones, talc, and superabsorbent polymers (eg, sodium polyacrylate). The reduction in friction allows the core unit 16 to more easily translate longitudinally to find a path of least strain during bending.

[0089] In various embodiments, outer sheath 20 may be colored and / or printed thereon to identify other properties of core unit 16 and / or core components, such as the type of optical fiber 14 comprising fiber set 18 (eg, 250 μm or 200 μm).

Abstract

An optical fiber cable comprising a jacket and a plurality of stranded core units, each core unit comprising a flexible sheath and a plurality of ribbons arranged in a ribbon pack, wherein each ribbon of the plurality of ribbons comprises a plurality of connecting optical fibers , so that 50%-70% of the cross-sectional area inside the sheath is occupied by the connecting optical fiber. The flexible skin may be an extruded PVC material that conforms to the shape of the stack of straps and keeps all the straps acting as a single body during bending.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] Under patent law, this application claims the benefit of priority from US Application No. 62 / 528,966, filed on July 5, 2017, and US Application No. 62 / 592,918, filed on November 30, 2017, the contents of which are the subject of this application is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates generally to communication fiber optic cables, and, more particularly, to high fiber count communication fiber optic cables having outer diameters configured to fit into conduits of specified dimensions. High fiber count communication cables can be used, for example, in super data center applications where the requirement for the fiber count in a single cable may exceed 3000 fibers. However, it is often necessary to route these high fiber density cables using existing conduits with small inner diameters. Additionally, the fiber density inside the cable is an importan...
