High Spectral Density Optical Communication Technologies 53 1 ein Vergleich von Vektor-The growth of Internet traf? c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit s level. To cope with the petabit class demands of traf? c in coming years the communication engineers are required to go beyond the incremental improvement of todays technology. A most promising breakthrough would be the introduction of modulation f mats enabling higher spectral ef? ciency than that of
