Optical data bus for connection between circuit boards of data processor

Abstract

Abstract PURPOSE: To provide an optical data bus for communication between logic cards of a data processing system by using a semiconductor laser that operates in a short wavelength region or a long wave region as a transmitter and a PIN diode as a receiver. CONSTITUTION: Reflecting mirrors 26 and 27 of a logic card 15a are located so that it may reflect radiation ray that is emitted from a laser 23a and collide it with a PIN diode 22a. Lasers 23a to 23f combine with PIN diodes 20a to 20f respectively and constitute an optical data bus that can transmit data from the right to the left, i.e., in the direction from a logic card 15f to a logic card 15a. Lasers 21a to 21f constitute an optical data bus that can transmit data from the left to the right, i.e., in the direction from the card 15a to the card 15f.
