Abstract
An optical data bus fixing board suitable for using an optical data bus as a signal transmission medium and an optical back plane board. A recess for inserting an optical data bus, which is made of a rectangular light transmissive resin substrate and comprises a step-wise side along the longitudinal direction and signal light incoming/outgoing areas formed by sloping the longitudinal end of each step at 45 degrees in relation to the substrate surface, is formed in the surface of a flat plate in order to easily and efficiently use the optical data bus as a signal transmission medium for interconnecting various signal processing circuits. The optical data bus is inserted and fixed within the recess by being pressed and biased from the back end by a first holding member including a reflective diffusion plate and from the side by a second holding member including a flat spring.
