Demonstration of in-line monitoring and dynamic broadband compensation of polarization dependent loss

We demonstrate in-line monitoring and dynamic broadband compensation of polarization dependent loss (PDL) for an 800-km optical link with 2.4-dB average PDL and 14-ps average polarization mode dispersion (PMD). The 2% power penalty tail of 10-Gb/s, wavelength division multiplexing (WDM) signals is reduced from 6.5 dB <2 dB within a 6-nm PDL compensation bandwidth.
