Recent Advances in Digital Longitudinal Monitoring and Tomography of Fiber-Optic Link

We review recent advances in longitudinal monitoring techniques that visualize distributed physical parameters along a fiber link solely from a coherent receiver. We discuss the working principle, design principle, and feasibility demonstration under practical DWDM transmissions.
