Low loss optical data terminal device for multimode fiber guide optical communication systems

摘要

The active data terminal device employs an array of multiple mode optical fiber guides as input-output devices, each abutted against a flat input-output focal face of an electro-optically active plate provided with opposed deflection modulation electrodes. Opposite the input-output focal face is a cylindrical mirror surface for refocusing the multiple- mode light from any predetermined input fiber guide into a second one of the array of fiber guides as selected by the voltage applied to the electrode pair.
