Calient said it had deployed what it claims in the world's largest photonic switch, 320 by 320 elements, in a secret U.S. government application provided by a systems integrator. The switch uses a prototype version of the OAO module. Mackey said the switch is not being used in a lab trial, but is "handling real traffic in a government application."
A month ago, Calient was one of several companies on a team called Lasor, for Label-Switched Optical Router, that received a $6.3 million Defense Advanced Research Projects Agency grant to explore optical label switching using G-MPLS and other control-plane methods. The Darpa contract has an alternate phase that will raise the total to $15.8 million.
Other members of Lasor include Agility Communications, Cisco Systems Inc., JDS Uniphase, Stanford University and the University of California at Santa Barbara.
