Abstract

The present invention provides an optical system that allows for the flexible location of an optical device that is coupled to a patch panel in a wiring closet or other optical signal source through a series of fiber optic cables and optical connections, or the flexible location of an array of such optical devices. The optical system includes, in part, one or more retractable optical fiber tether assemblies that each allow varying lengths of tether cable to be pulled and used. The retraction device of each of the optical tether assemblies may be disposed mid-tether cable, or may terminate the respective tether cable and incorporate the given optical device. In an exemplary wireless local area network (WLAN) application, each of the retractable optical fiber tether assemblies includes an integral transceiver and associated software. Thus, each of the retractable optical fiber tether assemblies functions as an antenna. The associated fiber optic cable carries both optical fiber to provide optical continuity and copper wire to provide electrical conductivity to the antenna array.

Claims
