Nonlinear Penalty Reduction Induced by PMD in 112 Gbit/s WDM PDM-QPSK Coherent Systems
Nonlinear Penalty PMD WDM PDM-QPSK Coherent Systems
2015/7/20
We show by simulation that when linear PMD is fully compensated by the receiver, the presence of DGD along the link reduces the amount of residual nonlinear penalty in 112 Gbit/s PDM-QPSK coherent sys...
Compensation of fibre impairments in digital coherent systems
Compensation fibre impairments digital coherent systems
2015/7/30
Coherent detection combined with digital signal processing (DSP) is a symbiotic relationship. Not only does DSP relax the requirements on the coherent receiver but it permits digital compensation of f...
