Appl. No.:

12/558390

Inventors:

Jeffrey Scott Barker - Statesville NC, US

Assignee:

Draka Comteq B.V. - Amsterdam

International Classification:

G02B 6/44

US Classification:

385100, 385109, 385110, 385114

Abstract:

Disclosed is a buffer tube that possesses a higher buffer-tube filling coefficient. Optical fibers enclosed within the buffer tube demonstrate improved attenuation performance when subjected to temperature variations between about −40 C. and 70 C. The buffer tube is suitable for deployments requiring mid-span access.

International Classification:

G02B 6/44

US Classification:

385113, 385100, 385109, 385112

Abstract:

Disclosed is a fiber-optic cable that possesses a high cable filling coefficient (and/or a high cable fiber density) yet ensures that its enclosed optical fibers demonstrate improved attenuation performance when subjected to temperature variations between about −40 C. and 70 C. The fiber-optic cable is suitable for efficient installation into ducts, such as via blowing.

Appl. No.:

12/557055

Inventors:

Jeffrey Scott Barker - Statesville NC, US
Paul Randall Baird - Hickory NC, US

Assignee:

Draka Comteq B.V. - Amsterdam

International Classification:

G02B 6/44

US Classification:

385110, 385105, 385113

Abstract:

The present invention provides optical fiber communication cable assemblies useful for separating and conveying individual fibers from a multiple optical fiber cable to connectors in a protective manner. The optical fiber cable assembly is suitable for outdoor use and includes a (i) cable with multiple optical fibers; (ii) a furcation unit attached to the cable for directing individual optical fibers from the cable to furcation legs; and (iii) multiple furcation legs receiving at least one of the optical fibers. The furcation legs include (i) a buffer tube surrounding the optical fiber; (ii) strength members surrounding the buffer tube; and (iii) a jacket surrounding the strength members. The furcation legs typically exhibit a tensile rating of at least about 50 pounds (lb), more typically 100 pounds (lb) or more. Moreover, the furcation legs typically exhibit total shrinkage of less than about 2 percent when cycled from +23 C. to −40 C.

Filed:

Oct 2, 1989

Appl. No.:

7/416607

Inventors:

Richard C. Nilsson - Hickory NC
Jeffrey S. Barker - Hickory NC

Assignee:

Alcatel NA Cable Systems Inc. - Claremont NC

International Classification:

G02B 644

US Classification:

350 9623

Abstract:

A pulling assembly for connectorized optical fiber cables is formed of a flexible metal braided hose portion for conveying a pulling force to said cable and for providing a chamber in which the cable connectors may be housed during a cable pulling operation. A cylindrical housing is attached to one end of said braided metal hose and includes a concentrically-arranged central strength member gripping apparatus and a buffer tube alignment structure disposed about the central strength member gripping apparatus. A crimping sleeve is attached to an opposite end of said cylindrical housing fixing said concentric arrangement within the cylindrical housing and being crimpably engageable with an outer surface of an optical fiber cable.

Appl. No.:

8/114778

Inventors:

Anthony A. Griser - Newton NC
Jeffrey S. Barker - Hickory NC

Assignee:

Alcatel NA Cable Systems, Inc. - Claremont NC

International Classification:

B29D 1100

US Classification:

264 128

Abstract:

An apparatus (10) for applying gel to a plurality of optical fibers (18) includes a housing (12) having a cavity (14) through which a plurality of separated optical fibers (18) are fed. The gel is provided to the cavity (14) from a gel reservoir (76) via a pump (74) that maintains the pressure and gel level to ensure that the optical fibers (18) are coated with gel to eliminate air gaps and thus prevent sticking among the optical fibers (18).
