Optical light-labeling on the rise

What: Light-labeling in optical networks

Why you should care: As the name suggests, light-labeling allows optical light transmissions to be labeled so that receivers throughout the network can track a particular light path and help ensure ongoing network performance. Traditionally, in a hybrid opto-electronic network, the optical transmission would have to be converted at various electronic monitoring points throughout the network. Light-label is less expensive and makes such conversion unnecessary.

Who's using it: AT&T Labs has been a driving force behind this innovation.
