Publication number: 20250180848Abstract: In one embodiment, a method of preparing an optical cable includes stripping a jacket of the optical cable to expose a buffer tube and one or more strength members, trimming the one or more strength members to a first distance d1 from an end of the jacket, trimming the buffer tube to a second distance d2 from an end of the one or more strength members to expose a plurality of optical fibers, grouping the plurality of optical fibers, applying a heat shrink tube over the buffer tube, applying heat to the heat shrink tube, applying adhesive to a first end and a second end of the heat shrink tube, and curing the adhesive.Type: ApplicationFiled: November 14, 2024Publication date: June 5, 2025Inventors: Kenneth Todd James, Boyang Lin, Alvin John McDonald, Hieu Vinh Tran

Patent number: 9651753Abstract: A fiber optic ribbon cable includes a stack of fiber optic ribbons, strength members surrounding the stack, and a jacket defining an exterior of the cable. The jacket forms a cavity through which the stack and the strength members extend. The stack has a bend preference, but the strength members are positioned around the stack or are flexible in bending such that the strength members 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 stack in order to allow the stack to bend and twist within the cavity with respect to the jacket as the cable bends, facilitating movement of the optical fibers of the fiber optic ribbons to low-stress positions within the cavity and decoupling the bend preference of the stack from transfer to the jacket.Type: GrantFiled: June 13, 2016Date of Patent: May 16, 2017Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: William Carl Hurley, Kenneth Todd James, James Phillip Luther, Radawan Ripumaree

Patent number: 9529152Abstract: A laser cleaving system includes a laser and a fixture including holders for respectively holding optical fiber ribbons at different angular positions. The fixture is rotatable relative to the laser for facilitating serial cleaving of the optical fiber ribbons. The fixture is configured for holding the ribbons in a predetermined manner so that the cleaved optical surfaces are of high quality and coplanar, such as when installed in a ferrule. For example, the fixture separates the ends of the ribbons from one another so that the ribbons being held by the fixture may be cleaved substantially independently from one another.Type: GrantFiled: October 31, 2014Date of Patent: December 27, 2016Assignee: Corning Optical Communications LLCInventors: Kenneth Todd James, Xin Liu, Alvin John McDonald

Patent number: 9360646Abstract: 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: GrantFiled: March 4, 2014Date of Patent: June 7, 2016Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: William Carl Hurley, Kenneth Todd James, James Phillip Luther, Radawan Ripumaree
