Meet the People who brought 400G to Optical

By Helen Xenos – How big of an undertaking is involved with bringing WaveLogic Ai to market? It’s more than just moving more bits.

What does it take to introduce a new, transformational networking technology to market? How do you deliver innovation that brings tremendous value to customers one year earlier than they could access it otherwise?

You use a team that has done it before. With 40G, with 100G, with 200G, and now with 400G.

Ciena’s WaveLogic Ai, our recently available next generation coherent technology, is establishing new performance and economic benchmarks in optical networking. Operators can now double the capacity they can carry for each transponder they deploy and go longer distances without the need for regenerators.

They can offer differentiated higher capacity wavelength services and gain efficiencies in DCI and metro applications with the industry’s first single carrier 400G solution. more>

Hydrogen flips switch on vanadium oxide

R&D Mag – If you are not a condensed matter physicist, vanadium oxide may be the coolest material you’ve never heard of. It’s a metal. It’s an insulator. It’s a window coating and an optical switch.

So what is vanadium oxide? It’s an oxidized form of the metal vanadium, an ingredient in hardened steel. When oxygen reacts with vanadium to form vanadium oxide, the atoms form crystals that look like long rectangular boxes. The vanadium atoms line up along the four edges of the box in regularly spaced rows. A single crystal of vanadium oxide can have many of these boxes lined up side by side, and the crystals conduct electricity like wire as long as they are kept warm.

“The weird thing about this material is that if you cool it, when you get to 67 C, it goes through a phase transition that is both electronic and structural,” said Rice’s Douglas Natelson, lead co-author of the study in Nature Nanotechnology. more> http://tinyurl.com/ch3c72y
