The evolution step for 40G is 100G (serial). That's the nominal bitrate per wavelength. Nobody would say that a vendor demonstrating 4x10G today would be "pushing 40G technology". So claming that by doing 10x10 "Infinera is pushing 100G" is not technically correct.
Sure, they integrate all the stuff in a chip but they still need 10 lambdas and some kind of link aggregation, so we are talking of two basically different technologies that have a set of different problems to solve.
In DSL this technology is called "bonding" (see G.998.x). It might be better described as "logical concatenation". Making more efficient use of existing technology seems to be the right way to go for these "one of" projects. Applying logical concatenation to optics is a great idea and a decent story. To get the "buzz" in today's press though, you have to have big bandwidth numbers.
But seriously LR, the "100G" title really is misplaced, unless you're going to start labeling other WDM technology by its aggregate bandwidth.
Exactly! Before you know it they will be installing supercomputers into the attic or basement of every new home. Won't that drive volume deployment of FTTx at 100G levels....
You're welcome to take the "100G" moniker with a grain of salt, but I do think non-serial 100GE is an effort worth following.
Don't laugh. The INQ site just reviewed a PC with TFLOPS power running at 500W. It does all sorts of real-time rendering. They called it a desktop supercomputer. Read it for yourself.
Besides, DOD funded ARPA. That started the Internet if memory serves correctly. They can fund 100-GigE too, if it serves their interests. Apparently it does, given their current budget spends on supers for these nuclear simulations. We have to keep up with N. Korea, after all.
each with good channel separation and at cost effective levels.
Nice that the existing fiber in the SC06 trial was able to handle it, although Bell Labs and Corning would rather not hear that...
