ABSTRACT:
An optical bus for distributing a light wave signal to a plurality of receivers. The optical bus (10) includes a generally cylindrical form (12) having a helical groove (14) inscribed on its outer surface. At a plurality of nodes (30), an optical fiber (16) wound about the form within the helical groove is caused to bend through a radius of curvature (22) sufficiently small so that a portion of the light propagating along the fiber is transmitted outside the fiber. A plurality of light detectors (26) are disposed at each of the nodes and are operative to produce an electrical signal corresponding to the portion of the light wave signal that is transmitted outside the fiber. The electrical signals are input to an electronic cross-connect matrix (108) and are selectively connected to a plurality of LEDs (112, 116, 120, 124) which each produce a light wave signal corresponding to the electrical signal for distribution to a receiver through a network of distribution optical fibers (126, 128, 130, 132).
