6 x 42.7 Gb/s Transmission Over Ten 200-km EDFA-Amplified SSMF Spans Using Polarization-Alternating RZ-DPSK
01 January 2004
We demonstrate the use of polrization alternation to dramatically improve performance in 42.7-Gb/s WDM transmission. Six channels are transmitted through ten 200-km (39-dB loss) standard-single-mode-fiber spans with amplification provided solely by erbium-doped fiber amplifiers.
