Publication number: 20150309274Abstract: A fiber optic ribbon cable includes a fiber optic ribbon or stack of ribbons, strength members surrounding the ribbon or stack, and a jacket defining an exterior of the cable. The jacket forms a cavity through which the strength members and the ribbon or stack extend. The ribbon or stack has a bend preference, but the strength members are flexible and do not have a bend preference. Furthermore, the jacket is structured such that the jacket does not have a bend preference. The cavity is sized relative to the ribbon or stack in order to allow the same to bend and twist within the cavity with respect to the jacket as the cable bends, facilitating movement of the corresponding optical fibers to low-stress positions within the cavity and decoupling the bend preference of the ribbon or stack from transfer to the jacket.Type: ApplicationFiled: March 4, 2014Publication date: October 29, 2015Applicant: Corning Optical Communications LLCInventors: William Carl Hurley, Kenneth Todd James, James Phillip Luther, Radawan Ripumaree

Publication number: 20150010283Abstract: Multi-fiber, fiber optic cable assemblies and related fiber optic components, cables, and methods providing constrained optical fibers within an optical fiber sub-unit are disclosed. The optical fiber sub-unit(s) comprises optical fibers disposed adjacent a sub-unit strength member(s) within a sub-unit jacket. Movement of optical fibers within a sub-unit jacket can be constrained. In this manner, the optical fibers in an optical fiber sub-unit can be held together within the optical fiber sub-unit as a unit. As a non-limiting example, the optical fiber sub-unit(s) may be exposed and constrained in a furcation assembly as opposed to the optical fibers, thereby reducing complexity in fiber optic cable assembly preparations. Constraining the optical fibers may also allow optical skew, reduction of entanglement between the optical fibers and the cable strength members to reduce or avoid optical attenuation, and/or allow the optical fibers to act as anti-buckling components within the fiber optic cable.Type: ApplicationFiled: September 24, 2014Publication date: January 8, 2015Inventors: William Carl Hurley, Wesley Allan Yates

The optical connector includes a body, a first array of openings defined in the body, and a second array of openings defined in the body. The second array is spaced from the first array. The bond between the ribbon matrix and the optical fibers prevents elongation of the split.Type: ApplicationFiled: June 12, 2013Publication date: December 18, 2014Inventors: William Carl Hurley, Eric Raymond Logan, Mark Tracy Paap
