ARMORED FIBER OPTIC ASSEMBLIES AND METHODS OF FORMING FIBER OPTIC ASSEMBLIES

摘要

Cables have dielectric armors with armor profiles that provide additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein, while retaining flexibility to aid during installation. The armored cables recover substantially from deformation caused by crush loads.

1. A method of forming an armored fiber optic assembly, comprising:
providing a fiber optic assembly comprising at least one optical fiber; extruding an inner layer of a dielectric armor around the fiber optic assembly, wherein extruding the inner layer comprises diverting a flow of an inner extrusion material with a first profiling feature to form a spiral strip; and extruding an outer layer of the dielectric armor around the inner layer from an outer extrusion material that is less rigid than the inner extrusion material, wherein the outer layer becomes at least partially bonded to the inner layer.
