METHOD OF IMPROVING RATIO OF SIGNAL TO NOISE OF TRANSMISSION SIGNAL AND OPTICAL INTERCONNECTION SYSTEM

摘要

PURPOSE: To improve the S/N of an electric data signal sent between two electronic modules. CONSTITUTION: An electric data signal from a 1st module is amplified electrically by a line driver 202. The amplified electric data signal has a sufficiently low power level so as not to cause a large disturbance in a power distribution network, then a plurality of links 200 placed nearby are operated by the signal at the same time. Then the electric data signal is converted into an optical data signal by a light source 204 and optically amplified in an optical path 208. The amplified optical data signal is detected by a photo detector 212, from which an electric signal whose S/N is substantially improved is generated.
