Modified Split-Step Fourier Method for Compensation of Nonlinear Fibre Impairments
2011 (English)In: 13th International Conference on Transparent Optical Networks (ICTON), 2011, IEEE conference proceedings, 2011, 1-4 p.Conference paper (Refereed)
In this paper, we investigate a modified split-step Fourier method to enable computationally-efficient digital nonlinearity compensation for a coherently-detected 112 Gb/s polarization multiplexed quadrature phase shifted keying transmission over a 1,600 km link (20×80 km) with no inline compensation. We report up to 80% reduction in required stages to perform nonlinear compensation, in comparison to the conventional backpropagation algorithm. This method takes into account the correlation between adjacent symbols at a given instant using a weighted-average approach to enable practical digital nonlinearity compensation.
