What is OC192?

I was in meetings today with Microsoft and going over some client stuff that I cannot really talk about here. But at this client the “hot backup” is done on a remote NAS over a OC192 line and I was like what the heck is that? Turns out that has a bandwidth of almost 10 gigabytes/sec (9.6 gb/s to be exact) - wow! Imagine all the things one can do with that pipe. Drooool! What is the fastest you have used? Till now I have worked on an OC12 - once this is up this would be my fastest!

PS - I am not a network engineer - I know enough to setup a dinky little domain and network at home but am not the expert - so don’t bombard me with all the nomenclature. *grin*

Update: Karan tells me there is a still faster <strong>OC768</strong> which runs at close to 40 gb/second.
