FILM FOR A FLAME-RETARDANT FIBER OPTIC CABLE

摘要

A flame-retardant fiber optic cable includes core elements, a film surrounding the core elements, and a jacket surrounding the film. The core elements include one or more optical fibers and at least one tube surrounding the one or more optical fibers. The material composition of the film differs from the jacket and the film is relatively thin.

主权项

1. A fiber optic cable, comprising:
(A) core elements comprising:
(i) an optical fiber; and(ii) a tube surrounding the optical fiber; (B) a binder film surrounding the core elements, wherein the binder film comprises:
(i) a base material, wherein the base material is primarily formed from a polymer, and(ii) a filler material, wherein the filler material is a flame-retardant material, and wherein the filler material is dispersed in the base material, and wherein the binder film is a binder for the core elements, opposing outwardly transverse deflection of one or more of the core elements; and (C) a jacket surrounding the binder film, wherein the binder film is thin, having an average thickness over a 10-meter length of the cable that is less than half an average thickness of the jacket over the 10-meter length.
