Abstract :
In this letter, we compare by simulation the performance of 111 Gb/s wavelength-division multiplexing (WDM) polarization-multiplexed quadrature phase-shift keying (PM-QPSK) on different commercial fiber types, in uncompensated links with 50-GHz channel spacing. We found that, besides low loss and large effective area, high local dispersion is very critical for enhanced system performance. Overall, different fibers deliver very different performance: under rather challenging assumptions, pure-silica core fiber allows us to achieve trans-Atlantic reaches whereas first-generation nonzero dispersion shifted fiber with low dispersion achieves less than one-third of that reach.
