DVI (Digital Video Interface) recently has become increasingly popular in the application of video transmission system. In view of the extreme of electrical performances, however, the traditional copper wire cable imposes limits on signal transmission distance and signal quality. In reality, optical fiber is of low dispersion, which in turn has the strength of longer signal transmission distance and better signal transmission quality in comparison to the traditional copper wire cable. Lightem LDVIEXT-1D-1A DVI extender provide the DVI Single-link Digital Video, Full-duplex RS232 and Audio transmitting capability through the optical fiber. This all optical transmitting solution can fulfill customer’s need in far-end Video/Audio broadcasting and data control, which shows the advantage of high performance and good signal quality as well as low cost.
