Deux solutions possibles pour le 100 gbit/s : Soliton/multiplexage en longueur d'onde : Les liaisons optiques sous-marines

Fundamental solitons give relatively good stability against line disturbances, and can be used for increasing the capacity of transoceanic lines. But the Gordon-Haus effect makes implementation difficult. A number of solutions are available for combating jitter, including sliding filters, on-line optical regeneration and alternating-amplitude solitons. Using soliton wave-division multiplexing, transoceanic line capacity can be increased up to 100 Gbit/s. Here, the main problem concerns the penalty arising out of non-linear soliton collisions. Though NRZ solutions still offer higher throughputs, soliton solutions appear to have a promising future.
