Abstract
Optical communications systems and methods are disclosed which involve routing optical signals through communications nodes which are controlled such that optical power arriving at input ports is linearly distributed to output ports. Such distribution may be realized by electro-optical, acousto-optical, or electro-mechanical controllable linear divider-combiner devices. Preferred systems including optical fiber links can be designed to make maximum use of physically realizable bandwidth, and to achieve high reliability in case of faults.
