Optical fibre communication link.

摘要

An optical fibre communication link for connecting a peripheral device to a computer system is presented. The communication link includes means for generating a video signal and means for transmitting the signal along an optical fibre between the computer system and the peripheral device. The transmitted video signal includes a reference pulse (1) of predetermined amplitude. Accordingly, there is now provided compensation means (15,16) for correcting changes in the characteristics of a received video signal which result from said optical communication link, and means (17,18) for using said reference pulse in a received video signal in order to control said compensation means. Preferably, the peripheral device is a display device.
