2.5 Tb/s (64x42.7 Gb/s) Transmission Over 40x100 km NZDSF Using RZ-DPSK Format and All-Raman-Amplified Spans
17 March 2002
We report 2.5 Tb/s (64 x 42.7-Gb/s) WDM transmission over 4000 km (forty 100-km spans) of non-zero dispersion-shifted fiber. This capacity x distance record of 10 petabit-km/s for 40-Gb/s systems is achieved using return-to-zero differential-phase- shift-keyed modulation, balanced detection, forward error correction, and distributed Raman amplification.
