PROBLEM TO BE SOLVED: To provide an optical bus having high energy efficiency and a signal processor, which is rich in the expandability of a system and attains the reduction of power consumption as well, by branching the light flux of signal light incident from a signal light incident part into plural beams and directing them toward plural signal light emitting parts. SOLUTION: On the end face of the optical bus on the front side, two signal light incident parts 101 are provided for making the signal light incident and at these incident parts 101, many refracting planes 102a and 102b consisting of a light flux branching part 102 are formed. Then, the refracting plane 102a refracts the incident signal light toward the signal light emitting part at a position A between two signal light emitting parts and makes that light enter into the optical bus, and the refracting plane 102b refracts the incident signal light toward the signal light emitting part at a position B between two signal light emitting parts and makes that light enter into the optical bus. In this case, by forming a refracting plane having further many angles at the light flux branching part 102, the incident signal light can be further refracted toward many signal light emitting parts. |
