Diversity - was: Fiber cut in SF area

[Rod.Beck at hiberniaatlantic.com (Rod Beck)]

Agreed. 

But bear in mind that DWDM infrastructure that does 80 to 120 waves per fiber pair is very expensive.

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.
