Abstract
We report on a 40 Gbit/s NRZ (non-return-to-zero) code transmission experiments including an dynamic Polarization mode dispersion (PMD) compensation. The dynamic PMD compensator is made up of two-stage four degrees. The first stage adopts polarization controller and fixed time-delayed line. The second stage is variable Differential Group Delay (DGD) element. The PMD monitoring technique is based on degree of polarization (DOP) as error signal. A novel practical adaptive optimization algorithm was introduced in dynamic adaptive PMD compensation. The experimental results show that the performance of the PMD compensator is excellent for 40Gbits/s NRZ transmission systems with the large the DGD. With this compensator, a significant improvement of system performance can be achieved in the eye pattern of a received signal.
