Fiber optic capabilities can be exploited to greatly simplify communication networks while at the same time greatly expanding their capabilities. With fiber optic technology, it becomes feasible to construct a broadband integrated services digital network (B-ISDN) that is scaled to cover the United States and can provide an STM-1 (155 Mb/s) interface for each subscriber. This paper describes an all-optical backbone for this national B-ISDN network. A switching technique based on spatial grating and shifting of optical beams is presented. With this technique, signals are directed along optically transparent paths through the backbone switches, and signal characteristics remain unaltered as signals flow through the backbone.
