We investigate the potential of optical n-stage FIR filter architectures for PMD compensation (PMDC) based on frequency-dependent optical power monitoring. The measurement information is used to partially estimate the channel's Jones matrix U (omega), and the filter parameters are adjusted based on solving a nonlinear least-squares problem which mimics the approximate inversion of U (omega) by the filter. Numerical studies of the optimization method and outage probability simulations show the robustness and scalability of the proposed concept.
