PDM-OFDM for upgrade scenarios:An investigation of OFDM-induced XPM on 42.8-Gb/s DPSK over SSMF and LEAF
Optical communications Nonlinear optics fibers
2010/6/9
We investigate the nonlinear tolerance of 42.8-Gb/s DPSK with PDM-OFDM neighbors. It is found that the XPM penalty scales with the OFDM-bandwidth and that for data rates up to 40-Gb/s delta powers are...
Experimental Demonstration of Joint SPM Compensation in 44-Gb/s PDM-OFDM Transmission with 16-QAM Subcarrier Modulation
Joint SPM Compensation PDM-OFDM Transmission Subcarrier Modulation
2009/7/14
We report the experimental demonstration of a recently proposed joint self-phase modulation compensation scheme in a single-channel 44-Gb/s polarization-division multiplexed OFDM transmission with 16-...
8x66.8-Gbit/s Coherent PDM-OFDM Transmission over 640 km of SSMF at 5.6-bit/s/Hz Spectral Efficiency
PDM-OFDM Transmission SSMF Spectral Efficiency
2008/8/6
8x66.8-Gbit/s DWDM transmission is demonstrated over 640-km SSMF with 9-GHz channel spacing. Employing coherent detected polarization-division-multiplexing OFDM with 16-QAM subcarrier modulation, a re...
Improved Nonlinear Tolerance of 112-Gb/s PDM-OFDM in Dispersion-Uncompensated Transmission with Efficient Channel Estimation
Nonlinear Tolerance PDM-OFDM Dispersion-Uncompensated Transmission Efficient Channel Estimation
2008/7/30
We show numerically that the nonlinear tolerance of a 112-Gb/s PDM-OFDM signal, coherently received with a robust and efficient channel estimation method, is substantially improved by fiber dispersion...
