Abstract :
Advanced modulation formats are proposed and analysed for next generation optical networks. The new evolving optical networks data rates of 100G and above require real time analog-to-digital conversion followed by real time digital signal processing. This is in order to allow increased spectral efficiency and full compensation of amplitude and phase distortion imposed by the optical channel in such high bitrates. Various approaches are presented, including discrete multi-tone and optical OFDM.
