Abstract

Coherent optical communications leveraged the fundamental philosophies and building blocks of mature wireless/copper-wire DSP technologies and has been a huge success with polarization-multiplexed QPSK at 100Gb/s per channel transponders currently in wide deployments. We discuss on further advances in DSP techniques to enable single-carrier transmission approaching 1 Tb/s as well as software-defined flexible transponders supporting adaptive modulation formats and elastic optical networks.
