Abstract :
70GHz-spaced 40 × 42.7 Gbit/s pre-filtered CS-RZ DPSK signals have been successfully transmitted over 8700 km for the first time, using all-Raman repeaters, "ABA" dispersion map and an ETDM receiver. Long-term stability was also confirmed with low-speed polarization scrambling and without using PMD compensation.
