A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

The bond between an armor and a cable covering jacket is controlled by introducing intervening material at the interface of the layers along selected bond regions. The intervening material can comprise particulate matter or a strip of material introduced at selected locations of the armor perimeter to allow ease of access at the selected regions.

Cable jacket with variable perimeter bond

A fiber optic cable including at least one optical fiber disposed within a cavity of a cable jacket and methods for manufacturing the same are disclosed. The cavity has a first cavity cross-sectional area and a second cavity cross-sectional area located at different longitudinal locations along the cable, where the first cavity cross-sectional area is greater than the second cavity cross-sectional area. The region of the second cavity cross-sectional area of the cable provides and/or increases the coupling level of the at least one optical fiber to the cable jacket. In further embodiments, the fiber optic cable is a dry cable having one or more dry insert within the cavity for cushioning and/or optionally providing water-blocking for the cable.

A fiber optic cable including at least one optical fiber and at least one dry insert disposed within a cavity of a cable jacket and methods for manufacturing the same are disclosed. The dry insert has a first thickness and a second thickness located at different longitudinal locations along the dry insert, where the first thickness is greater than the second thickness. The region of the cable having the first thickness of the dry insert provides and/or increases the coupling level of the at least one optical fiber to the cable jacket. In further embodiments, the optical fiber(s) have a predetermined level of coupling to the cable jacket that is about 0.1625 Newtons or more per optical fiber for a thirty meter length of fiber optic cable.

Fiber optic cables using dry inserts for coupling and methods therefor

A buffered optical fiber includes at least one optical fiber and a buffer layer. In one embodiment, the buffer layer generally surrounds the optical fiber and has a non-round cross-section that includes a plurality of wings that are an integrally formed by the buffer layer. Additionally, the buffered optical fiber may form a portion of a fiber optic cable that allows a relatively small bend radius while maintaining optical performance. Optionally, the optical fiber may be a bend resistant optical fiber for preserving optical performance. Additionally, other fiber optic cables that allow relatively small bend radii are also disclosed.

Fiber optic structures that allow small bend radii

Fiber optic cables are disclosed that allow a relatively small bend radius and/or may kink while still preserving optical performance. In one embodiment, the fiber optic cable includes at least one optical fiber, a first strength member, a second strength member, a core material, and a cable jacket. The core material generally surrounds the optical fiber, the first strength member, and the second strength member and the core material is deformable for cushioning the optical fiber. The cable jacket generally surrounds the core material and allows a bending radius of about 10 millimeters or less while maintaining a suitable level of optical performance.

Fiber optic cables that kink with small bend radii

A tubeless fiber optic cable is disclosed, including at least one optical fiber extending in a longitudinal direction, and an outer jacket extending in the longitudinal direction so as to surround the optical fiber. The outer jacket has a cross-section defining an inner surface and an outer surface. At least one strength member extends in the longitudinal direction along the outer jacket and is disposed so that a portion thereof protrudes from the inner surface of the outer jacket, so that when a ripcord is pulled from the outer jacket separation of the outer jacket occurs, thereby allowing access to a cavity containing the optical fiber. In another embodiment, the ripcord protrudes from the inner surface of the outer jacket.
