Essex WDM Devices Sold to Telcordia for DoD Optical-CDMA Project

Essex Corporation will supply five of its hyperfine WDM devices to Telcordia Technologies for use in a DARPA project to build an Optical Code Division Multiple Access (CDMA) system that would enable secure, multi-user high bandwidth sharing of the same optical channel. Later this year, Essex will team with Telcordia and the University of Central Florida, School of Optics/CREOL on the project. Essex said the primary advantage of O-CDMA would be that a user’s connection could be dynamically reconfigured by assignment of a code rather than being dedicated to a WDM channel. Today, WDM channels are statically configured making it difficult and expensive to reconfigure connections between users. Essex’s Hyperfine WDM technology has the ability to dynamically encode and decode an optical signal.
