The rapid growth of the user demands in telecommunication needs continuous and serious development work entails. It is the same with media player systems as well. In the last century, the film industry has undergone enormous technological progress, which has been resulted the widespread distribution of movies. Nowadays the home theater system is already an integral part of many homes, which owners are constantly trying to keep up with the system changes and developments.

Recently the biggest innovation is the media server, which supplies the devices capable to play high definition multimedia files. By installing, the launch and handling of the home movie system becomes extremely simple for all ages and does not require any special skills.

In flats or industrial use areas (for example: casinos, hospitals, movie floors) a star topology network is being installed, which connections are currently using UTP cable, but why don’t we replace these by optical cables in the future?

In my thesis I do measurements to confirm that the light guide technology is suitable to transmit high-quality media content as well, and what's more the case of larger distances is only an opportunity for optics.

The minimum bend radius has been ascertained at which the various types of fiber optic cable is still capable of signaling, and how much problem caused by the bends in field installation. The optimal cable type for our system has also been chosen.

In several measurement arrangements, comparing many fault indicator metrics I prove that there is no significant difference in quality of transmission in case of baseband and modulated signals between using optical or electrical technologies.
