Section 6.4. The polarization of the data signal was scrambled for the transmission
and “descrambled” before detection. BER measurements confirmed the perfor-
mance of the PMD compensator, which decreased the penalty by more than 8 dB
and thus enabled error-free 160 Gb/s transmission over this fiber link with only
1.3 dB penalty compared to back-to-back performance. All settings related to
polarization and PMD were found in an automatic adaptation process.
6.6 TRANSMISSION EXPERIMENTS
6.6.1 Review on 160 Gb/s Transmission Experiments
In 1995, the first 160 Gb/s OOK transmission experiment was performed in the
NTT laboratories based on soliton transmission over 200 km DSF using AP-multi-
plexing [87] . The pulse source was an MLFL followed by an optical ...
