Abstract
Over the years, with advances in communications technology, telecommunications management system reform and full liberalization of telecommunications market gradually, the development of optical fiber communication presents the booming situation.
With the continuous development of Internet, people want the Internet to send more and more multimedia information. Video signal transmission is the core of multimedia messaging. Play the video signal in the computer terminal is not a problem, the key problem is that the signal compression and transmission technology. In this paper, using optical fiber as the transmission medium of a broadband video signal transmission system block diagram, and in conjunction with the schematic diagram, explanation and analysis of the broadband video transmission system is the key technology, the use of the equipment.
This article describes the optical fiber communication technology, the single-mode and multi-mode transmission has been studied to show the development of optical communication technology.
Key words: optical fiber communication; single mode and multimode transmission; communications transmission;
