OPTICAL TIME DIVISION MULTIPLEXER AND OPTICAL TIME DIVISION DEMULTIPLEXER

摘要

PROBLEM TO BE SOLVED: To make a device configuration simple and achieve cost reduction by using a channel discrimination signal added to the head of a multiplexed signal to discriminate a channel.;SOLUTION: Buffers 110-1 to 110-4 output voltage signal trains V1 to V4 at timings given by a clock generator 150. Discrimination signal giving circuits 120-1 to 120-4 add two or more consecutive channel discrimination signals consisting of multi-bit signal patterns to heads of corresponding voltage signal trains V1 to V4. Drivers 130-1 to 130-4 convert voltage signal trains outputted from the discrimination signal giving circuits 120-1 to 120-4, to current signals. A time division multiplexed optical signal train P0 is generated on the basis of the current signals.;COPYRIGHT: (C)2006,JPO&NCIPI
