Abstract: A fiber optic cable assembly comprises first and second cable legs each including a tight buffer surrounding coated optical fibers, and a reduced thickness buffer connecting region, with cable leg being devoid of any surrounding jacket and any tensile strength member. A fiber optic cable assembly devoid of a tensile strength member mechanically coupled to a connector comprises a travel limiting feature that serves to limit travel of the ferrule and inhibit ferrule decoupling when tension is applied to a fiber optic cable.

Abstract: Cables have dielectric armor with an armor profile that resembles conventional metal armored cable. The armor can be formed as a single layer, without requiring an outer jacket layer. 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. The assemblies can additionally be lightweight and relatively inexpensive to manufacture.

Abstract: An armored fiber optic cable includes fiber optic assembly, including at least one optical fiber, and dielectric armor in the form of an extruded polymeric tube surrounding the fiber optic assembly. The dielectric armor has at least one layer formed from a rigid material having a Shore D hardness of about 65 or greater. Further, the dielectric armor has an armor profile such that the dielectric armor has an undulating surface along its length.
