Cogent, for example, openly advertises 680G lit capacity for its intercity links; I have not idea if that's just marketing or not. Perhaps some people on list who work for these providers can provide some data. On Fri, Jan 27, 2012 at 11:10 AM, Anurag Bhatia <me@anuragbhatia.com> wrote:
Hello Ray
You are refering to dark fiber capacity or is that lit capacity and already in use?

Well, those are the numbers we can see from a single transceiver (right now mostly 10G and some 40G right now, and 100G on its way); but most of the big players are using multiples of these with DWDM and link aggregation. I'd say the actual numbers are closer to 680G average right now, per path.

Just curious to know at what bandwidth big ISP's like AT&T, Verizon,
Level3, Cogent etc are operating? Are all at or above 40Gbps core bandwidth?
Probably a mix of 10G, 40G and 100G as appropriate. By 2014, that might tilt more heavily toward 40G and 100G. From what I've seen, most peering connections at public IXPs are one or more 10G links. Private peering connections could certainly be higher, if the providers at both ends feel it makes good business sense.

not a problem. the vast majority of the states is like a developing country [0], the last mile is pretty much a tin can and a string. so this will effectively throttle the load.
