Dec 21, 1998

Appl. No.:

09/217527

Inventors:

Anne G. Bringuier - Taylorsville NC

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 644

US Classification:

385113, 388109

Abstract:

A fiber optic cable suitable for indoor applications includes a core tube surrounding a plurality of coated optical fibers; a jacket formed of a polymer material surrounding the core tube; and at least one layer of strength members disposed between said core tube and said jacket. The jacket has an outer diameter of not greater than about 7 to 12 mm and the coated optical fibers experience a short-term increase in signal attenuation of no more than about 0. 01 dB when the cable is looped in a radius of 5 centimeters.

International Classification:

G02B 644

US Classification:

385109

Abstract:

A fiber optic cable having both water blocking and flame retardant properties that is particularly useful for indoor or indoor/outdoor applications. In one embodiment, the fiber optic cable includes at least one buffer tube, at least one optical fiber disposed within the buffer tube, a composite tape surrounding the buffer tube that comprises a layer formed of an inherently flame retardant material and at least one coating a water swellable material, and a jacket surrounding the composite tape. The fiber optic cable can also include a water blocking element disposed within the buffer tube. The water swellable coatings of the composite tape and the water blocking element within the buffer tube therefore inhibit water migration along the length of the cable, while the flame retardant layer of the composite tape provides fire resistance. In another aspect, a dry fiber optic cable that includes a buffer tube comprised of an inherently flame retardant material, at least one optical fiber disposed within the buffer tube, a first tape comprised of a water swellable material that at least partially surrounds the at least one optical fiber, at least one roving extending lengthwise along the buffer tube and having a coating comprised of a water swellable material, and a jacket surrounding the buffer tube and the at least one roving. As such, the buffer tube provides flame retardant properties, while the first tape and the water swellable coating of the at least one roving inhibit water migration along the length of the cable.

Assignee:

Corning Cable Systems LLC - Hickory NC

International Classification:

G02B 6/44

US Classification:

385114, 385100

Abstract:

A fiber optic cable includes at least one optical waveguide, at least one dry insert and a cable jacket. The at least one optical waveguide and at least one dry insert are at least partially disposed within a cavity of the cable jacket. The at least one dry insert has a first and second portion that are connected to one another. In one embodiment, at least one fold is present between the two portions.

International Classification:

G02B 6/44

US Classification:

385113, 385100, 385114, 385103

Abstract:

A fiber optic cable includes at least one optical fiber, at least one strength member, at least one dry insert, and a cable jacket. The cable jacket has a cavity with a generally rectangular cross-section with the at least one optical fiber and the at least one dry insert disposed therein. The at least one optical fiber has a predetermined level of coupling to the cable jacket that is provided by the at least one dry insert within the cavity of cable jacket. The predetermined level of coupling is about 0. 1625 Newtons or more per optical fiber for a thirty meter length of fiber optic cable. Additionally, fiber optic cables of the present invention are also suitable as a portion of a cable assembly.

International Classification:

US Classification:

385100, 385109, 385114

Abstract:

Disclosed are fiber optic assemblies having at least one optical fiber and a water-swellable powder within a tube and/or cavity and methods for making the same. Fiber optic assemblies of the present invention use relatively low-levels of water-swellable powder while still effectively blocking the migration of tap water and/or saline solutions of 3% by weight along the tube and/or cavity. Furthermore, cleaning of the optical fibers is not necessary before connectorization like with conventional fiber optic cables that use a gel or grease. Generally speaking, at least some of the water-swellable powder is transferred to the inside surface of the tube, cavity, optical fiber or the like; rather, than being a loose powder that is able to migrate within the tube or cavity. Moreover, the existence of water-swellable powder within the fiber optic assembly or cable is nearly transparent to the craft since relatively low-levels are possible.
