Abstract
An optical cable assembly is provided. The cable assembly includes a plurality of subunits surrounded by an outer cable jacket, a furcation unit and optical connectors coupled to the end of each of the subunits. Each of the subunits includes an inner jacket, a plurality of optical fibers; and a tensile strength element. The first tensile strength element and the inner jackets of each subunits are coupled to the furcation unit, and the optical fibers and tensile strength elements of each subunit extend through the furcation unit without being coupled to the furcation unit. The subunit tensile strength element and optical fibers of each subunit are balanced such that both experience axial loading applied to the assembly and, under various loading conditions, the compression of the subunits is controlled and/or the axial loading of the optical fibers is limited to allow proper function of the optical connector.

13. An optical communication cable assembly comprising:
-
an outer cable jacket; a first tensile strength element surrounded by the outer cable jacket that has an axial rigidity; a subunit comprising; an inner jacket defining a passage; a plurality of optical fibers located within the passage; a second tensile strength element located within the passage; wherein the subunit has an axial rigidity; a furcation unit, wherein the first tensile strength element and the inner jacket of the subunit are coupled to the furcation unit, wherein the plurality of optical fibers and the second tensile strength element of the subunit extend through the furcation unit without being coupled to the furcation unit; and an optical connector coupled to an end of the subunit; wherein the cable assembly has a maximum rated cable load and a total axial rigidity; wherein, under axial loading applied at the furcation unit, the subunit experiences a portion of the axial load that causes compression of a portion of the subunit located between the furcation unit and the optical connector, the compression being relative to the amount of axial loading, further wherein both the optical fibers and the second tensile strength element experience some of the portion of the axial loading of the subunit; wherein a ratio of the axial rigidity of the subunit to the total axial rigidity of the cable assembly is such that compression of the subunit is between 0.1% and 2.5% of an initial length of the portion of the subunit between the furcation unit and the optical connector at the maximum rated cable load. - View Dependent Claims (14, 15, 16)
