At the same time, the application of high-order modulation formats enables coherent optical communication to have higher single-wavelength channel spectrum utilization compared to traditional system systems.
Ngesikhathi esifanayo, ukusetshenziswa kwamafomethi wokumodayisa okuphezulu kwenza ukukhulumisana kwe-optical okuhambelanayo kube nokusetshenziswa kwesiteshi se-spectrum esisodwa esiphezulu uma kuqhathaniswa nezinhlelo ezivamile.
