Abstract

Distributed communications systems employing one or more free-space-optics (FSO) links, and related components and methods are disclosed. In one embodiment, a distributed communications system is provided in which one or more links of a communications path located between a central unit and a remote unit include FSO provided by one or more FSO components. The FSO component(s) can replace optical fiber (or copper) cable assembly and the associated electrical/optical and optical/electrical converter circuitry. Note that FSO and fiber cable links may be used in a mixed fashion depending on the particular requirements of a given installation project for a distributed communications system. Use of such FSO components may allow temporary installations to be effectuated with greater ease and more economically since physical cable is not required for the FSO portion of the communications path. Likewise, installation obstacles associated with physical cable may be eliminated for portion of the communications paths that employ FSO.
