PMD mitigation application of MZI-SOA based optical 2R regeneration in the receiver

We propose a new application of the MZI-SOA-based optical-2R regeneration, which can exactly compensate for the PMD (polarization mode dispersion) penalty resulting from 35ps-DGD in a 10 Gb/s system with 18 dB OSNR/0.1 nm. This demonstrates the effectiveness of the optical-2R in the receiver for PMD mitigation.
