COMPENSATION OF FIBER NONLINEARITY IN 40×32 GBAUD LONG-HAUL DWDM TRANSMISSION
RESUMO
This paper investigates the performance of 5.12 Tbps Dense Wavelength-Division Multiplexing (DWDM) transmission using 40 channels with 128-Gbps Polarization Division Multiplexing-0.3 return to zero-quadrature phase-shift keying Quadrature Phase Shift Keying (PDM-0.3RZ-QPSK) modulation format. The prime advantage of the proposed work is improving the transmission performance by increasing the signal quality and the maximum reach. This is achieved by using the digital backpropagation algorithm as a nonlinearity compensation technique. The considerable nonlinear effects are the self-phase modulation (SPM), the cross-phase modulation (XPM). The maximum achievable transmission distances obtained at a bit error rate of 3.8×10-3 are 4800 km and 2400 km for the single and DWDM transmission, respectively.
