Optical switches have been around a long time. The technology is solid and it works. Problem is, to date, there just hasn't been a big market for them.
But, now may be the time for optical switches. Not, as they've been previously marketed as stand alone devices, but instead as components inside any number of other systems:
- ROADMs
- High end data center storage devices
- High density/capacity layer 2 switches
- Very large routing systems
Why? The move to 100G makes optical switching one of the best ways to mesh backbone components of both carrier and data center network backbones. No processing, little delay and minimal loss. And, with the prices of optical switches falling rapidly, their time - as a component of larger devices - may be now.
What do you think?
