Paper Abstract

In this paper, we first provide analysis and discussion on the optimal symbol rate for long-haul transmission. In particular, the optimal subband bandwidth in a multi-band DFT-Spread OFDM (MB-DFT-S OFDM) system is studied. We then carry out numerical simulation of 107 Gb/s MB-DFT-S OFDM systems and find the optimal subband bandwidth is 3.5 GHz for dispersion un-compensated systems. We finally show experimental demonstration of the nonlinearity improvement of DFT-S-OFDM over conventional OFDM systems.
