An optical fiber carrying structure that includes a jacket and a rip cord is provided. Optical fiber cables are used to transmit data over distance. Generally, large distribution cables that carry a multitude of optical fibers from a hub are sub-divided at network nodes into subunits. To remove a jacket of a subunit, the subunit may be provided with an access feature such as a rip cord. Described herein is a rip cord for use with optical fiber carrying structures.

Fiber carrying structure with rip cord and related method

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.

Optical fiber cable and assembly

A fiber optic ribbon having a first subunit and a second subunit. The first and second subunits including a plurality of respective optical fibers being connected by respective primary matrices. The first and second subunits being generally aligned along a plane with a secondary matrix contacting portions of the first and second subunits. The secondary matrix having at least one end portion and at least one medial portion. The at least one medial portion and the at least one end portion of the secondary matrix are separated by a gap along at least a portion of the longitudinal axis, thereby defining a preferential tear portion. In other embodiments, the at least one medial portion is recessed relative to the at least one end portion.
