Agreed. But bear in mind that DWDM infrastructure that does 80 to 120 waves per fiber pair is very expensive. REgards, Roderick S.

And if the 10 gig wave is from 1 Wilshire to 60 Hudson with hundreds of regen huts and 30 POPs in between? How that affect the capex cost?
Sure, the capex cost of offering full diversity is substantial; my point was just that the cost of switching STM64 signals at the endpiints need not be a significant issue, since you only have to switch the optical path, which is cheap to do and highly reliable, and the kit to do that will only make up a tiny fraction of the rest of the capital and operations cost. -- Neil
