Abstract

Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The dielectric armor provides additional crush and impact resistance for the optical fibers and / or fiber optic assembly therein. The armored cables recover substantially from deformation caused by crush loads. Additionally, the armored fiber optic assemblies can have any suitable flame and / or smoke rating for meeting the requirements of the intended space.

Description

[0001] priority application [0002] This application claims the benefit of US Provisional Application 61 / 168,005, filed April 9, 2009, the entire contents of which are incorporated herein by reference. [0003] Related applications [0004] This application is related to US Application 12 / 261,645, filed October 30, 2008, the entire contents of which are incorporated herein by reference. This application is also related to US Provisional Application 61 / 174,059, filed April 30, 2009. technical field [0005] The present invention relates generally to fiber optic assemblies, and more particularly to armored fiber optic assemblies having dielectric armor. Background technique [0006] Fiber optic cables and assemblies should maintain optical performance when deployed in an intended environment while also meeting any other requirements of that environment. For example, indoor fiber optic cables used in riser and / or duct spaces may require certain flame ratings and mechanical ...
