Shorthand for optical-to-electrical-to-optical, a conversion that takes place in some optical transport gear.
ROADMs don't do this; they keep traffic in the optical domain, as do all-optical switches.
The perceived disadvantage to all-optical transport is that there's no opportunity to peek into the wavelength to see the traffic itself. This means, for instance, that the traffic can't be groomed, not until the wavelength is terminated and the data converted back to electrical form.
That's why some optical gear converts the traffic to electronic form, makes decisions or modifications as necessary, then puts it back onto a wavelength. O-E-O.
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.
