Broad bandwidth seamless transmission of 3.56 Tbit/s over 40/spl times/100 km of NZDF fibre using CSRZ-DPSK format

Eighty-nine 42.7 Gbit/s, 100 GHz-spaced WDM channels in a 72 nm seamless band were transmitted over 40×100 km of fibre using carrier-suppressed return-to-zero differential-phase-shift-keyed modulation format with a balanced receiver, all-Raman amplification, a broadband dynamic gain equaliser and a zero-dispersion discrete Raman amplifier.
