| 摘要 |
Optical communications systems and methods are disclosed which involve routi ng optical signals through communications nodes which are controlled such that optical power arriving at input ports i s linearly distributed to output ports. Such distribution may be realized by eletro-optical, acousto-optical, or electro-mechanical controllable linear divider-combiner devices (401, 405, 411; 415). Preferred systems including optical fiber links can be designed t o make maximum use of physically realizable band- width, and to achieve high reliability in case of faults.
