The companies said Tuesday that they'll be using 16QAM modulation. The channel width would amount to 60 wavelengths per fiber, for a total potential bandwidth of 24Tbit/s per fiber.
In addition to speed, the companies will be focusing on the potential power savings of 400Gbit/s transmission. Their work is part of an Ultra-High Speed and Green Photonic Networks program under the Ministry of Internal Affairs and Communications (MIC).
The project will last "until 2014," according to the companies' press release.
Why this matters
It's looking certain that a 400Gbit/s generation will exist in optical transmission and in client-side Ethernet. While many in the industry have stressed the need to start researching 1Tbit/s immediately, projects such as this one would seem to indicate that carrier demand will support an intermediate step.
Light Reading founder Steve Saunders talks with VMware's Shekar Ayyar, who explains why cloud architectures are becoming more distributed, what that means for workloads, and why telcos can still be significant cloud services players.
A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
