The chapter describes high-speed optical data transmission based on optical time-division multiplexing (OTDM) with the focus on optical signal processing in the key building blocks of OTDM transmission systems. The OTDM transmitter is described including pulse generation, pulse shaping, and modulation of an optical pulse train. The OTDM receiver is discussed for direct detection and coherent detection systems. This includes signal processing using various optical gates, timing extraction devices, and optoelectronic base rate receivers, as well as the operation of phase-diversity homodyne receivers and coherent receivers as OTDM demultiplexers. A final section focuses on combating impairments in fiber links, i.e., using optical signal processing for the compensation of linear and higher order chromatic dispersion and polarization-mode dispersion as well. © 2012 Springer-Verlag Berlin Heidelberg.
