Alcatel-Lucent's 400Gbit/s Feat

France Télécom - Orange and Alcatel-Lucent say they have deployed the "world's first optical link offering a capacity of 400 Gigabits per second per wavelength in a live network." The link is operational between Paris and Lyon. I'm asking my boss if I can spend a few weeks in both cities to take pictures. Meanwhile, the companies added:

    With capacity four times higher than the maximum bandwidth currently available and using 44 wavelengths, the new optical link can transmit up to 17.6 Terabits per second (Tbps) of traffic in total.
I'd be happy enough if I could get just one wavelength to my home. Not sure why the French have to be so extravagant about everything. For more:

Having 500G cards is something different than having 500G wavelenghts. Infinera should stop mixing these 2. What really matters is the spectral efficiency and total capacity per fiber.

-áHi Phil,

Thanks for sharing your thoughts on this ALU announcement, and for asking about in-service deployments beyond 100G.-á

We may not call it bragging, and it may not be 400G, but we definitely have more than one 500G link in-service today.-á One example, we have announced CenturyLink has deployed the DTN-X and is running traffic on live 500G links today.-á This is just one of the 22 customers that have selected the DTN-X to date.

Sorry we can't help with the wavelength to your home, good luck with that!

brag? More like the last gasp of a dying animal at the end of the DTN-X sword. The real 1TB. Au revoir.-á

400G is the new 1TB. Or something like that.-á
Have any other equipment vendors bragged about an in-service 400G link lately?

Broadband speeds are ramping up across Europe as the continent, at its own pace, follows North America towards a gigabit society. But there are many steps to take on the road to gigabit broadband availability and a number of technology options that can meet the various requirements of Europe’s high-speed fixed broadband network operators. During this radio show we will look at some of the catalysts for broadband network investments and examine the menu of technology options on offer, including vectoring and for copper plant evolution and the various deployment possibilities for FTTH/B.
