Abstract:
A digital signal transmission apparatus comprising:optical transmission means for converting serial digital signals sent from a peripheral device over a coaxial cable into serial digital optical signals and transmitting the resulting signals; andoptical receiving means for receiving the serial digital optical signals from said optical transmission means, for converting the received serial digital optical signals into serial digital signals and for sending the resulting signals to a coaxial cable,wherein said optical transmission means includes a cable auto-equalizer for setting the serial digital signals to a preset level, a clock generator for extracting a clock frequency from the serial digital signals of a preset level in order to generate serial clock signals, a timing correction unit for receiving the serial clock signals and the serial digital signals of a preset level and for latching the serial digital signals at the timing of the serial clock signals, and an electro-optical converter.
