During the JITC evaluation, Sycamore's SN 9000 successfully completed a battery of standards conformance and systems performance tests involving a variety of broadband optical and electrical interfaces, including procedures for traffic capacity and stress response, failure recovery, traffic protection and re-routing, and verification of data and control planes.

"We are very pleased to successfully complete JITC interoperability testing of the SN 9000," said Jim Mooney, vice president of product management and marketing at Sycamore. "This milestone is further evidence of Sycamore's commitment to the demanding and rapidly evolving communications requirements of our military, and our ability to meet those needs with a broad portfolio of intelligent bandwidth management platforms."
