Abstract
The invention relates to an optical fiber cable including an outer sheath containing a plurality of optical fibers separated into at least two optical fiber modules, each of said modules consisting of a module sheath surrounding a respective group of optical fibers. According to the invention, the module sheath is formed by a film of plastics material. The film is, for example, wrapped widthwise around the group of optical fibers, a first face of the film being superposed on and fixed to a second face of the film over a portion of given width of said film.
Claims22
A method of forming a sheath for an optical fiber module, said module being designed to form part of an optical fiber cable including an outer sheath enclosing at least two optical fiber modules each including a respective group of optical fibers,
- the method comprising the steps of:
- deforming a pre-formed film tightly around said group of optical fibers;
- and
- fixing the film thus deformed around the group of optical fibers in order to surround, enclose, and hold said group of optical fibers.
An optical fiber cable including an outer sheath containing a plurality of optical fibers separated into at least two optical fiber modules, each of said modules comprising a respective group of said optical fibers and a film of plastics material wrapped around the respective fiber group with portions of said film overlapping other portions of said film to form a module sheath tightly wrapping and enclosing said respective group of optical fibers.
