title: Comparison of 80 × 112-Gb/s PDM-QPSK system performance over large effective area fiber and standard SMF with Raman amplification.
abstract: We experimentally investigate the transmission performance of 80 × 112-Gb/s polarization-division-multiplexed quadrature phase shift keying (PDM-QPSK) signals over large effective area fiber and standard single mode fiber (SSMF) links with Raman amplification. The large effective area fiber offers higher optimum launch power and longer reach than SSMF. The maximum reach of 5200-km is obtained using large effective area fiber. The Gaussian noise (GN) model is explored to fit with experimental data for optimum power.
