Abstract

We compared the transmission performances of 600 Gbit/s PM-64QAM WDM signals over
75.6 km of single-mode fibre (SMF) using EDFA, discrete Raman, hybrid Raman/EDFA, and firstorder or second-order (dual-order) distributed Raman amplifiers. Our numerical simulations and
experimental results showed that the simple first-order distributed Raman scheme with backward
pumping delivered the best transmission performance among all the schemes, notably better than
the expected second-order Raman scheme, which gave a flatter signal power variation along the fibre.
Using the first-order backward Raman pumping scheme demonstrated a better balance between the
ASE noise and fibre nonlinearity and gave an optimal transmission performance over a relatively
short distance of 75 km SMF.
