Automated polarization control demonstrated in a 1.28 Tbit/s (16/spl times/2/spl times/40 Gbit/s) polarization multiplexed DWDM field trial

We have demonstrated automatic polarization control in a field trial over 116 km of SSMF with 16 channel DWDM (100 GHz spacing) based on polarization multiplexed 2/spl times/40 Gbit/s NRZ signals for a total capacity of 1.28 Tbit/s after FEC decoding.
