  • Publication number: 20230258902
    Abstract: A fanout tube for a furcation of a fiber optic cable assembly carrying a plurality of optical fibers includes an outer casing defining an outer surface and an inner cavity configured to receive one or more of the optical fibers therethrough. The outer casing includes an outer jacket that defines a passageway and at least one strength member disposed in the passageway. The strength member includes at least one tensile strand and a substrate that at least partially covers the tensile strand. At least a portion of the substrate defines a confronting surface configured to form at least a portion of the inner cavity of the outer casing and be isolated from the tensile strand, and thus inaccessible to optical fibers being inserted through the fanout tube. A method of forming a fiber optic cable assembly having a furcation formed from such fanout tubes is also disclosed.
