OPTICAL FIBER BUNDLE

摘要

An optical communication cable bundle is provided. The bundle includes a bundle jacket and a plurality of optical fiber subunits surrounded by the bundle jacket. Each optical fiber subunit includes a subunit jacket defining a subunit passage and a plurality of optical fibers located with the subunit passage. The thickness of the bundle jacket may be less than a thickness of each of the subunit jackets. The tensile strength of the bundle jacket may be less than the tensile strength of the subunit jacket, and the tear strength of the outermost bundle layer may be less than the tear strength of the subunit jacket. The subunit jacket may be formed from a fire resistant material that has an oxygen limiting index that is greater than an oxygen limiting index of the material of the bundle jacket.
