Your impression is pretty much correct. WorldCom
bought/obtained a large quantity of fiber before DWDM
capability was widely available, and has not spent
very much money on CapEX in the past couple of years.
Their current focus seems to be trying to maximize the
usage of their existing infrastructure.
Two questions -- can anyone verify/offer more
insights/point to better
resources on WorldCom's DWDM startegy?
And -- as the rumor mill seems to suggest -- is it
indeed true that despite
obvious network economics SONET-based OC-12 and
OC-48 circuits are indeed
enjoying lower street prices than DWDM oc-12/48
circuits? Any thoughts as to
why this info is indeed correct?
This is also true, because a large number of providers
are in a similar place to WorldCom - i.e.
overprovisioned SONET gear, and don't want to upgrade
to a DWDM-based system until their SONET cicuits
absolutely need it. It shouldn't be all that
surprising - where you'll really see a lot of DWDM is
those providers who had loaded up on dark fiber, and
are now starting to light them.
