Thats not true. New DWDM allows up to around 120gbps. Check out the SAFE pipeline. In a few years africas new ipv6 infastructure will make us look like the redneck retards we have running the country.
DWDM runs multiple "sonet" pipes on a single fiber. IE-- your example of 120 gbps would actually be 12 separate wavelengths each running 10 gbps or oc192 not a single wavelength at 120 gbps. (320-400 gbps second DWDM machines are not that uncommon-- 32-40 oc192's) So in single "beam" of light oc768 is as fast as you will see deployed-- however DWDM tech could allow someone to run multiple oc768 on a single fiber for even faster DWDM.

What's funny is us worrying about africas infrastructure. As if they will be needing any such thing any time soon. Get real.

I guess I should have said manufacturable. I started working on OC-768 switches in 2000. It has taken 5-6 years for it to get to the point that you could sell a switch with the technology (i.e not a one off prototype). I suspect it will take just as long for OC-1536 or what-ever they call it to reach a mass producible state too.

OC-768 is the top end of current technology right now, but on the other hand a typical MPLS switch might have hundreds of OC-768 ports (usually 4 per line card), so that is a alot of available bandwidth.

I was thinking the same. 40 Gbps could be used up real quick with a bunch of HD channels.
