Optical communication systems carry the bulk of all data traffic worldwide. This book
introduces multi-Terabit s transmission systems and three key technologies for next generation
networks. A software-defined multi-format transmitter an optical comb source and an optical
processing scheme for the fast Fourier transform for Tbit s signals. Three world records
demonstrate the potential: The first single laser 10 Tbit s and 26 Tbit s OFDM and the first
32.5 Tbit s Nyquist WDM experiments.
