Filed:

May 29, 1990

Appl. No.:

7/529991

Assignee:

AT&T Bell Laboratories - Murray Hill NJ

International Classification:

G02B 644

US Classification:

385101

Abstract:

A hybrid optical fiber, copper conductor transmission media cable (20) which is suitable for use in local area network application includes a core (22) comprising two arrays (25,40) of longitudinally extending portions. One array (25) includes optical fibers disposed between two strength members (27--27) whereas the other array comprises metallic conductors (42--42). Each array includes a matrix material (30,45) in which the longitudinally extending portions are enclosed with adjacent portions being connected by a web (32,47). The two arrays are enclosed by a jacket (50) which has an oval shaped configuration. The configuration of component portions of the cable as well as the materials thereof are determined to cause the neutral axis of bending to be in a desired location which minimizes losses in the transmission media.

International Classification:

G02B 644

US Classification:

385103

Abstract:

An optical fiber cable includes one or more component cables. In one embodiment, the component cable has an elongated central aramid yarn member surrounded by at least one, and preferably six, optical fibers. An aramid yarn layer surrounds and contacts the optical fibers, and a plastic jacket envelopes and contacts the aramid yarn layer. In a second embodiment, the component cable includes optical fibers, preferably twelve in number, embedded in aramid fibers. A plastic jacket in contact with the aramid fibers, encloses the aramid fibers with its embedded optical fibers. In the cable of this invention, component cables of the first and/or second embodiments are wound about an elongated, central strength member with a reverse-oscillated lay. An outer jacket encloses and holds the reverse-oscillated lay of the component cables. The invention also includes a system for manufacturing the cables of this invention.

Abstract:

An optical fiber cable (20) includes a core (22) comprising at least one optical fiber (23) which is enclosed in a tubular member (28) and which includes a non-metallic sheath system (30). The sheath system includes two contiguous layers (40, 50) of non-metallic strength members which extend longitudinally along the cable and which are wrapped helically in opposite directions about the tubular member. The layers of strength members are enclosed in a plastic jacket (36). At least some of the strength members which are capable of withstanding expected compressive as well as tensile loading are coupled sufficiently to the jacket to provide a composite arrangement which is effective to inhibit contraction. Those strength members cooperate with the remaining strength members to provide the cable with a predetermined tensile stiffness and to cause the cable to be relatively flexible.
