By using optical amplifiers and dispersion-compensating devices, state-of-the-art DWDM optical systems can span thousands of kilometers at 10 Gbit/s, and several hundred kilometers at 40 Gbit/s.
Usando amplificadores ópticos e dispositivos de compensación de dispersión, os sistemas ópticos DWDM poden percorrer miles de quilómetros en 10 XB/s, e varios centos de quilómetros de 40 XB/s.
