Abstract:
We demonstrate simultaneous self-phase-modulation-based 2R regeneration of 2 x 10.65-Gb/s polarization-division-multiplexed (PDM) signals using a single section of highly nonlinear fiber (HNLF). Mitigation of inter-channel nonlinearities is achieved through a bidirectional configuration, rejecting of backward Stimulated Brillouin Scattering noise is obtained by signal re-polarizing before the offset filter and putting the center wavelength of filter at the short wavelength side of the signal. The power penalty improvement up to 2.0 dB for two PDM signals at 10(-9) BER is achieved.
