TLDR
In this paper, the authors investigated electronic compensation techniques to mitigate chromatic dispersion in a phase modulated optical coherent detection system, which added flexibility to the dynamically routed optical networks.Abstract:
High speed optical fiber transmission performance is severely degraded due to chromatic dispersion in the fiber. Contrary to conventional dispersion compensation techniques by dispersion compensated fiber, in this work electronic compensation techniques are investigated to mitigate chromatic dispersion in a phase modulated optical coherent detection system. Such electronic compensation techniques add flexibility to the dynamically routed optical networks. Performances of electronic mitigation techniques of chromatic dispersion are compared and their applicability limits are evaluated.read more

TL;DR: In this paper, a unified multiblock nonlinear model for the joint compensation of the impairments in fiber transmission is presented, and it is shown that commonly used techniques for overcoming different impairments are often based on the same principles such as feedback and feedforward control, and time-versus-frequency-domain representations.
