Abstract

An optical communication cable includes a cable jacket formed from a first material, a plurality of core elements located within the cable jacket, and an armor layer surrounding the plurality of core elements within the cable jacket, wherein the armor layer is a multi-piece layer having a first armor segment extending a portion of the distance around the plurality of core elements and a second armor segment extending a portion of the distance around the plurality of core elements, wherein a first lateral edge of the first armor segment is adjacent a first lateral edge of the second armor segment and a second lateral edge of the first armor segment is adjacent a second lateral edge of the second armor segment such that the combination of the first armor segment and the second armor segment completely surround the plurality of core elements.

First claim

What is claimed is:

1. A method of manufacturing an optical communication cable, the method comprising:
surrounding a plurality of core elements with a multi-piece armor layer, wherein the armor layer comprises:
a first armor segment extending a portion of the distance around the plurality of core elements, the first armor segment having a first lateral edge and an opposing second lateral edge; and
a second armor segment extending a portion of the distance around the plurality of core elements, the second armor segment having a first lateral edge and an opposing second lateral edge;
wherein the first lateral edge of the first armor segment is adjacent the first lateral edge of the second armor segment and the second lateral edge of the first armor segment is adjacent the second lateral edge of the second armor segment such that the combination of the first armor segment and the second armor segment completely surround the plurality of core elements; and

extruding a cable jacket around the armor layer.

2. The method of claim 1 , further comprising:
extruding a film around the plurality of core elements prior to extruding the cable jacket.

3. The method of claim 1 , wherein the plurality of core elements comprises a stack of fiber optic ribbons.

4. The method of claim 1 , further comprising coupling the first lateral edge of the first armor segment to the first lateral edge of the second armor segment and coupling the second lateral edge of the first armor segment to the second lateral edge of the second armor segment.

5. The method of claim 1 , further comprising embedding a first elongate strength member and a second elongate strength member within the cable jacket.

6. The method claim 5 , wherein the first elongate strength member comprises a first pair of elongate strength members and the second elongate strength member comprises a second pair of elongate strength members.

7. The method of claim 3 , further comprising application of a water-blocking layer to surround the stack of fiber optic ribbons.

8. The method of claim 7 , wherein the water-blocking layer comprises a water-blocking tape, foam or gel.
