I am not primarily talking about DWDM, I am talking about 10km (and
perhaps up to 40km) SMF light with CWDM wave spacing (20nm) for metro
Enabling fairly easy development of 40GE 8 wave transport without
transponders (colored optics directly into external CWDM mux) tips the
balance for me in favor of 40GE serial, if cost projections are similar
for 40GE serial vs 4x10GE CWDM.
