Fractional orthogonal frequency division multiplexing (FrOFDM) exhibits considerable flexibility in the axis of multiplexing and a medium characteristic between OFDM and Nyquist optical time division multiplexing. FrOFDM subcarrier effect on nonlinear distortion in long haul transmission has not experimentally been verified. In this work, we used a highly nonlinear fiber under relatively short transmission conditions for experimental emulation of nonlinear signal distortion under long haul transmission conditions considering no phase modulation in time domain for non-telecom application. We examined the suppression effect on the distortion and confirmed that, FrOFDM subcarriers greatly suppress nonlinear distortion.

Abstract
Fractional orthogonal frequency division multiplexing (FrOFDM) exhibits considerable flexibility in the axis of multiplexing and a medium characteristic between OFDM and Nyquist optical time division multiplexing. FrOFDM subcarrier effect on nonlinear distortion in long haul transmission has not experimentally been verified. In this work, we used a highly nonlinear fiber under relatively short transmission conditions for experimental emulation of nonlinear signal distortion under long haul transmission conditions considering no phase modulation in time domain for non-telecom application. We examined the suppression effect on the distortion and confirmed that, FrOFDM subcarriers greatly suppress nonlinear distortion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
