Home -> Community -> Mailing Lists -> Oracle-L -> RE: Grid
10-gig ethernet IS hideously expensive, but its the switching that's expensive. The actual bearer circuit is standard dark fiber. 10-gig ethernet is actually kind of a cheat - it uses 4 2.5 gig wavelengths to create the 10-gig throughput. So each port has to be a DWDM or use 4 different strands of fiber (hence the cost). There's no distance problems running 10gigE.
Be that as it may, though, the circuit we're talking about here is almost certainly going to be an OC-192 SONET loop. These have been around for a while - large-scale ISPs use them for core cross-country connectivity. You can bear ATM (though why you'd want to....), IP, MPLS, etc. over it.
Thanks,
Matt
