Abstract: Composite communications cable are provided that include a central conductor, a dielectric spacer that substantially surrounds the central conductor, an outer conductor that substantially surrounds the dielectric spacer, a jacket that surrounds the outer conductor and a non-buffered optical fiber positioned between the central conductor and the dielectric spacer. An outer surface of the non-buffered optical fiber is within 50 microns of the outer surface of the central conductor. The positioning of the optical fiber adjacent an outer surface of the central conductor may protect the optical fiber from damage.

Abstract: Coaxial connectors are provided that include a body assembly, an internally-threaded nut, and a conductive anti-friction bearing mechanism disposed between the body assembly and the nut. In some embodiments, the conductive anti-friction bearing mechanism may comprise a plurality of ball bearings that are configured to maintain an electrical connection between the body assembly and the internally-threaded nut.

Abstract: A fiber optic cable includes: a plurality of optical fibers, the fibers divided into a plurality of fiber optic subunits, each of the subunits defining generally a circle having a first diameter; at least one elongate filler element, the filler element comprising a cellulosic material, wherein in end view the filler element defines generally a circle having a second diameter that is substantially the same as the first diameter; and an outer jacket surrounding the optical fiber subunits and the filler element, wherein the total number of fiber optic subunits and fillers elements is at least four. In this configuration, the cable can pass typical flame testing while being manufactured at a lower cost than current cable.
