Computer system provided with infrared communication cable

摘要

A computer system includes an input adapter and an external optical communication transceiver. The adapter has a plug which can be mated with the keyboard socket and a duplicated keyboard socket for allowing an input device such as a keyboard to be electrically connected with the system unit. The external optical communication transceiver is electrically connected with an optical point-to-point communication controller through the adapter. The optical communication transceiver and the adapter can be electrically connected with each other by either an extension cable or a flexible tube, thereby the computer system and other infrared-equipped devices can be aligned for user convenience's sake regardless of allowable link angle and distance.
