We exploit excess spectrum of DWDM systems, where the Nyquist bandwidth of the optical signals is narrower than the channel spacing. Digitally generated cyclic-spectrum RZ shaping is shown to enhance nonlinear tolerance. Simulations show a 26% reach increase in a 7-channel DWDM PolMux 16QAM long-haul transmission.
