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.
