Résumé

In this paper, we present a 10x100km transmission experiment of coherent 100 Gbps QPSK-OFDM and 200 Gbps 16QAM-OFDM over both uncompensated G.652 and G.655 fibre lines. 100 Gbps QPSK-OFDM shows error-free performance after 1000 km of transmission with a BER ~ 1x10-7 over G.652 fibre and ~ 1x10-5 over G.655 fibre, opening large OSNR margins for a field implementation. As expected, 200 Gbps 16QAM-OFDM is less efficient, but is still able to achieve 1000 km without error over G.652 fibre line, even if margin with respect to the soft-decision FEC threshold (fixed at BER ~ 2x10-2) is tiny. We also notice that G.652 fibre largely outperforms G.655 fibre at 100 Gbps and 200 Gbps whatever the modulation format considered, reinforcing the interest of G.652 fibre infrastructure for modern optical communication systems using high-order QAM.
