No, you don't get it (though I'll admit the statement is hyperbolic).
If you need OC-768 connectivity, there is only one place to go today. If
you really need it (and few do), you have the money to pay for it and a
business that does not make existing hardware appropriate.
I tend to suspect that the need for OC-768c is still rather limited.
Most providers are primarily aggregators of massive numbers of small
pipes. With almost no OC-768c Sonet gear in the field, my guess is that
this gear will be used mostly by a handful of carriers who can make
fiber available at minimal cost for dark fiber connectivity at major
In the vast majority of the places where more bandwidth is needed, just
adding more OC-192s (or even OC-48s) is often a more economical answer,
especially if you own lots of excess fiber and/or WDM gear.
As the the comments about "toys", yes, our network is taxpayer funded.
It is run for the USDOE with federal funding; no CA state funds are
involved. It is NOT a play network. It is a full-production high
availability network which provides the only access to a number of very
large and, in the view of some, very important facilities. It is an
unusual network in terms of the volume of point to point flows. Things
like fusion and high-energy physics generate simply astonishing amounts
of data. Terabytes are not uncommon. We don't need OC-768 today, but we
expect to need it in the next few years.
