Abstract

An optical fiber cable includes a jacket and modules including optical fibers. The jacket has an interior that forms an elongate conduit between proximal and distal ends. The modules extend lengthwise through the conduit without being bound together in a pattern of twisting or wound together in a pattern of stranding. Also, the jacket and modules are sized such that free space is provided within the conduit between the modules and the jacket. The jacket is at least ten meters long, and the orientation, alignment, and size of the modules allow individual modules to slide lengthwise relative to one another through the conduit. Pulling one of the modules from the proximal end of the jacket while holding the other modules fixed at the distal end of the jacket draws the one module further into the jacket on the distal end of the jacket.

First claim

What is claimed is:

1. A method of manufacturing an optical fiber cable assembly, comprising steps of:
attaching local connectors to optical fibers of legs of the optical fiber cable assembly, wherein the legs are formed from distal portions of modules that project from a distal end of a jacket of the optical fiber cable assembly;
sliding the modules axially through the jacket relative to one another in order to change the length of the corresponding legs, thereby adjusting the length of the legs for a desired configuration of the optical fiber cable assembly;
attaching a multi-fiber connector to optical fibers of the modules at the proximal end of the jacket; and
attaching the multi-fiber connector to the strength element on one end of the jacket;
attaching the furcation body to the strength element on the other end of the jacket; and
tensioning a strength element extending through the jacket and fixing the strength element at ends of the jacket while not correspondingly tensioning the modules, such that when the jacket is stretched the strength element is tensioned before the modules and tensile loads experienced by the optical fiber cable assembly along the jacket are primarily borne by the strength element.

2. The method of claim 1 , further comprising steps of:
severing and removing excess length of the modules; and
aligning proximal ends of the modules with the proximal end of the jacket.
