Exactly. At the EQIX/ASH GPF Telia and AOL both said they were using 10GE
cross-connects for private peering. So that means at least 3-4 major
networks are using them in production in a LAN, MAN or WAN environment.
When you are aggregating lots of a GEs, there isn't really a great,
cost-effective way to move all of these bits cost-effectively. nxOC48 is
pretty cheap, but a little ugly if you need the bandwidth unchoked. 10GE is
supposed to get there, but at a 10xGE price, not a OC192 type price.
The real advantage of Copper 10G is that eventually you can deploy it to all
the existing copper [inside] plants that people have currently deployed.
Just like GE, it eventually just becomes tolerant enough to use existing
wiring. I would be very happy if the first boxes that came out with these
long range xenpaks were muxes that would take 10xGE -> 1x10GE -- this would
solve the uplink problem from smaller gear in a heartbeat.
