Publication number: 20020186939Abstract: A fiber optic cable comprising an optical ribbon (20), a jacket (40), and a buffer material (30) between the optical ribbon (20) and the jacket (40). Buffer material (30) includes at least one volume of buffer material defining a stress-cushioning zone (32) between optical ribbon (20) and jacket (40), the stress-cushioning zone being operative to substantially decouple jacket (40) from ribbon (20) in the region of the stress-cushioning zone (32) thereby inhibiting the application of stress to optical ribbon (20). Buffer material (30) includes at least one volume of material at an intermediate buffer zone (35) held substantially tight against an intermediate portion (25) of optical ribbon (20) for inhibiting the twisting of optical ribbon (20). The volume of material at the stress-cushioning zone (32) is substantially larger than the volume of the buffer material of the intermediate buffer zone (35).Type: ApplicationFiled: August 2, 2002Publication date: December 12, 2002Inventors: Daniel J. Rutterman, Ronald D. Schiefer

Patent number: 6295401Abstract: A fiber optic cable having optical sub-units each respectively including at least one optical fiber ribbon. The optical sub-units are removably connected together by a web of jacketing material. The optical fiber ribbons are generally twisted about their respective longitudinal axes by stranded strength fibers disposed about the optical ribbons. The fiber optic cable can be used as a stand alone component or, for example, in fan-out or break-out cables.Type: GrantFiled: December 21, 1999Date of Patent: September 25, 2001Assignee: Siecor Operations, LLCInventors: Daniel J.

Patent number: 5966489Abstract: An optical cable (50) for use in a fiber optic cable assembly (10). Fiber optic cable assembly (10) comprises conventional single fiber connectors (80,82), a dual fiber connector (84), and a connector fan-out housing (86). Dual fiber connector (84) is of the type used to interface with, for example, an opto-electrical and electro-optical transducer. Fiber optic cable (50) comprises a ribbon (20). Ribbon (20) includes optical fibers (24), a variable spacing section (23), and a transition section (27) inside connector housing (86). Optical fibers (24) are spaced at a nominal fiber-to-fiber distance, defined as spacing S, in cable section (21). Variable spacing section (23) comprises sub-carrier sections (22a,22b) comprising plastic tubes, e.g. furcation tubing, the spacing of which is variable. Spacing S matches the spacing needed in an electrical system to avoid crosstalk.Type: GrantFiled: June 30, 1997Date of Patent: October 12, 1999Assignee: Siecor CorporationInventors: Shannon N. Harwell, Daniel J. Rutterman

Patent number: 5917978Abstract: A buffered optical fiber includes a coated optical fiber loosely contained within a space delimited by the inner surface of a plastic tube. The outer surface of the coated optical fiber is formed of non-stick material such as TEFLON. No filler material is inserted between the coated optical fiber and the inner surface of the plastic tube. The plastic tube may have an inner diameter of 400 .mu.m and an outer diameter of 900 .mu.m. The buffered optical fiber is suitable for use in interconnect cables.Type: GrantFiled: January 10, 1997Date of Patent: June 29, 1999Assignee: Siecor CorporationInventor: Daniel J. Rutterman
