25 x 40-Gb/s Co-Polarized DPSK Transmission Over 12 x 100-km NZDF with 50-GHz Channel Spacing
01 January 2003
We report the first transmission of co-polarized 40-Gb/s channels with 0.8-b/s/Hz spectral efficiency. We transmit 25 channels over 1200 km of non-zero-dispersion fiber (1600 km with adjacent channels orthogonally polarized). This result was obtained using differential-phase-shift keying, and without forward error correction.
