Wavelength conversion of RZ-OOK PDM signals by XPM in a highly nonlinear fiber

Abstract

Wavelength conversion of RZ-OOK signals in PDM systems based on XPM in high-nonlinear-fiber (HNLF) through a polarization-diversified loop is experimentally demonstrated. Less than 1dB eye-diagram-based SNR penalty is obtained for 10-G/bs RZ-OOK PDM signals.
