Abstract: Methods of controlling the position of an optical fiber having a minimum bend radius within an optical fiber channel in a fiber optic cable having a small footprint are disclosed. The position of the optical fibers is controlled so that the fiber is not bent at a radius below its minimum bend radius.

Abstract: A cable includes a channel with an aspect ratio that houses optical fibers therein. The cable includes first and second stranded conductors on opposing sides of the channel. The channel is arranged with respect to the stranded conductors so that the fibers assume low strain positions in the channel when the cable is bent.

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.

Abstract: Armored fiber optic assemblies and methods are disclosed that include a dielectric armor and at least one bend-resistant multimode optical fiber. The dielectric armor has an armor profile, thereby resembling conventional metal armored cable to the craft. The dielectric armor provides additional crush and impact resistance and the like for the optical fibers and/or fiber optic assembly therein. The dielectric armor is advantageous to the craft since it provides the desired mechanical performance without requiring the time and expense of grounding like conventional metal armored cables. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space. The use of at least one bend-resistant multimode optical fiber allows for improved bend performance for the armored fiber optic assemblies, allowing for tighter cable routing as compared to armored fiber optic assemblies having conventional multimode optical fiber.

Abstract: Fiber optic articles, assemblies, and cables preserve optical performance by using optical waveguides having a core, a cladding, and a coating system according to the present invention. Moreover, the optical articles, assemblies, and cables of the present invention may achieve performance levels that were previously unattainable, for instance, the present invention contemplates acceptable optical performance for wavelengths such as 1625 nm and higher. Additionally, articles, assemblies, and/or cables of the present invention advantageously preserve optical performance, i.e., have relatively low delta attenuation, when subjected to manufacturing processes and/or environmental conditions such as temperature cycling. In other words, the articles, assemblies, and cables can withstand increased stress/strain before having significant attenuation.
