Ultra-high transmission capacity through space multiplex operation
Today's optical transmission systems are increasingly reaching the theoretical limits of their transmission capacity. Higher modulation formats as well as wavelength and polarization multiplexing are used here. A further increase in transmission capacity can be achieved by using spatial multiplexing using different transverse field distributions (modes). In theory, the transmission capacity can be increased by the number of modes used for spatial multiplexing.
As part of this DFG project (project number: KR 3596/7-1), the potential and limits of such systems are to be investigated. Here, both effects on the transmission link and the behavior of erbium-doped fiber amplifiers in such systems are considered. The project is carried out in cooperation with the TU Berlin.
