Transmission performance of N X 160 Gbits(-1) densely dispersion-managed optical fibre systems
Résumé
We carefully analyse the feasibility of N x 160 Gbit s(-1) ultra- long haul transmissions in densely dispersion-managed ( DDM) fibre systems. By using a novel analytical approach, we design highly optimized configurations of DDM fibre systems. Transmission performances of the analytically designed DDM fibre systems are evaluated using numerical simulations. We show that single-channel transoceanic transmissions at 160 Gbit s(-1) may be achievable in DDM fibre systems, whereas multi-channel transmissions result in dramatically poor performances.
