DEFINITION

Classification: 359/118

(under subclass 115) Subject matter wherein multiple optical stations are interconnected via a network of fiber optics to enable transmission and reception between the stations.

(1) Note. Electrical wiring networks are excluded since they are not optical waveguides.

370, Multiplex Communications, appropriate subclasses for a nonoptical bus transmission local area network having token passing, loop or ring, etc.

385, Optical Waveguides, appropriate subclasses for the fibers themselves without the optical multiplex communication environment.
