Phase Noise Canceled Polarization-Insensitive All-Optical Wavelength Conversion of 557-Gb/s PDM-OFDM Signal Using Coherent Dual-Pump

We study the effect of phase noise canceled polarization-insensitive all-optical wavelength conversion (AOWC) of orthogonal frequency-division multiplexing (OFDM) signals, which is based on four-wave-mixing in high-nonlinear optical fiber using dual-pump. An AOWC experiment of polarization division multiplexing OFDM (PDM-OFDM) 8/16/32-QAM signals is investigated. A DFB laser with linewidth of 10 MHz is employed as the coherent dual-pump seed. The measured results show that the received signal after wavelength conversion by utilizing coherent DFB dual-pump has the same BER performance as back-to-back. Furthermore, AOWC of 557-Gb/s superchannel discrete Fourier transform-spread PDM-OFDM with eight-QAM (DFTS PDM-OFDM 8-QAM) signal is proposed and experimentally demonstrated based on the studied coherent dual-pump scheme. Negligible OSNR penalty (<;0.8 dB) is observed at 7% FEC limit (BER = 3.8 × 10-3) after wavelength conversion. Our demonstration shows that the phase noise transferred from the pumps can be effectively eliminated. It also shows that AOWC enables practical implementation on the polarization multiplexing dynamic optical networks at the nodes where wavelengths conflict.
