  • Abstract
    We numerically and experimentally investigate spectrum optimization techniques including adjustment of subcarrier symbol rate and subcarrier frequency spacing for multi-subcarrier modulation. Improvement of nonlinear tolerance is experimentally evaluated in Nyquist-FDM-DP-QPSK through 2,400 km transmission.
