Application of fiber-optic techniques in the transport and access transmission networks of mobile systems

Fixed access networks widely employ fiber-optical techniques due to the extremely wide bandwidth offered to subscribers. In the recent years enormous increase of user data is visible in mobile systems too. Therefore the importance of fiber-optical techniques within the fixed transmission/transport part of mobile systems is inevitably increasing. This paper summarizes a few reasons and gives examples why and how fiber-optic techniques are employed efficiently in 2G networks.
