Technical Issues for 40G DWDM

Technical issues for 40G transport such as sensitivity, chromatic dispersion(CD) and polarization dispersion(PD) have been solved, enabling commercial deployment of 40G technology.  Most of the technical challenges associated with 40G DWDM are already widely understood, as challenges from the 10G world taken to more demanding levels. In some cases, the tighter tolerances associated with driving… Read More »
