The GIG-BE project is a Department of Defense initiative, which involves the deployment of an all-optical network linking Department of Defense sites around the world using secure and dedicated links. The Optical Transport System portion includes both Ultra-Long Haul transport and integrated all-optical switching. GIG-BE will connect intelligence, command and operational locations with a secure high-bandwidth capability over a physically diverse, optically meshed network. "We believe that the Corvis optical networking solution is a strong technical and economic fit for the Optical Transport System requirements," said Dr. David Huber, chairman and CEO. "Since Corvis is still the only company that has ever constructed and deployed a commercial all-optical network, we believe that we are well-positioned to assist SAIC and DISA in the task of deploying this next-generation, all-optical, global network." Corvis plans to discuss this invitation and its overall business operations on its second quarter investor conference call scheduled for Thursday, July 31, 2003. The conference call will begin at 5:30pm and will last approximately 45 minutes. The conference call will be available on the company's website at www.corvis.com.
