OPTICAL INFORMATION TRANSMISSION SYSTEM

摘要

PURPOSE:To reduce the integrated loss of a common bus, and to provide a slave processor additionally by making an optical branching ratio of signal power on optical branching unbalanced. CONSTITUTION:A signal C transmitted from a master processor 1 is branched by an unblanced branching type optical branching device 15 into a signal A passed through the optical branching device on a common bus side, and a signal B passed through an optical branching device on the side of a slave processor 2. Consequently, the integrated loss from the master processor to the slave processor is reduced and n9mbers of slave processors are connected.
