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...
Volterra Nonlinear Compensation of 100G Coherent OFDM with Baud-rate ADC, Tolerable Complexity and Low Intra-channel FWM/XPM Error Propagation
Coherent Communications Fiber Optic Communications
2010/6/9
Nonlinear tolerance of PDM-OFDM transmission with in-line dispersion compensation, e.g. legacy ultra-long-haul submarine links, is substantially improved by a Volterra non-linear compensation scheme, ...
Reduction of XPM penalty by sub-bit delay demodulation of DQPSK
Phase modulation Fiber optics communications
2010/6/8
We show that using a shortened delay in the demodulator for DQPSK channels can significantly reduce the XPM penalties caused by transmitting 40Gb/s DQPSK channels alongside 10Gb/s OOK channels.
XPM Tolerant Adaptive Carrier Phase Recovery for Coherent Receiver Based on Phase Noise Statistics Monitoring
XPM Tolerant Adaptive Carrier Phase Recovery Coherent Receiver Phase Noise Statistics
2009/7/17
According to the monitored phase noise statistics, the averaging weights in carrier phase recovery is adaptively optimized. Comparing with existing optimization techniques, 1dB Q value improvement can...
All-Optical TDM to WDM Signal Conversion and Partial Regeneration Using XPM with Triangular Pulses
All-Optical TDM WDM Signal Conversion XPM Triangular Pulses
2008/8/3
We propose a new all-optical, all-fibre scheme for conversion of time-division multiplexed to wavelength-division multiplexed signals using cross-phase modulation with triangular pulses. Partial signa...
