re: Ciena, Infinera Push 100-GigE The technology sounds good, especially for the system vendors. However, the component vendors need volume to make money. With the 2007 forecast for 40G at ~1K units, nobody makes money.

re: Ciena, Infinera Push 100-GigE Volume is one thing. Money is another. DOD is big into supercomputers for nuclear weapons testing. They have budget to spend tens of millions of dollars on any number of projects. They want that 100Gbps. That is a start that has spawned more than one new market.

re: Ciena, Infinera Push 100-GigE 10x10G is not 100G. Two basic differences: - Wavelength usage; -need for link aggregation or inverse multiplexing.
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.

re: Ciena, Infinera Push 100-GigE "But seriously LR, the "100G" title really is misplaced, unless you're going to start labeling other WDM technology by its aggregate bandwidth."

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.

re: Ciena, Infinera Push 100-GigE So you mean Ciena and Infinera are not being fully up-front? Are they engaging in spin? I'm shocked!

LOL.

re: Ciena, Infinera Push 100-GigE MaterialGirl,

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....

re: Ciena, Infinera Push 100-GigE I seem to recall 4x10G being called "40 Gig" back in the day, although I'll admit my memory could be faulty. And I'm told there was once a Frame Relay 4x2.5G effort that presumably would have been called "10 Gig."

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.

re: Ciena, Infinera Push 100-GigE Dear litereading:

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.

re: Ciena, Infinera Push 100-GigE At the heart of the technical challenges is that Infinerap apparently cannot get direct modulation of their integrated lasers to 100Gb/s
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...
Cheers
