Patent number: 7706685Abstract: An optical network system, including multiple nodes, an optical switch, and a switch controller, is configured to achieve communication in the optical domain. Each node is configured to receive both high frequency and low frequency inputs, generally utilized for handling data and addressing information, respectively. The two types of information are combined to create an amplitude modulated optical signal. Subsequently, the two types of information are separated by examining the optical power average of the signal being transmitted. Using one portion of the signal for addressing information, the switch controller can perform necessary routing and arbitration functions. Appropriate communications can then be sent back to the nodes and the optical switch to achieve the necessary configuration. The protocol utilized allows for subsequent arbitration and data transmission cycles, allowing the system and switch controller to configure transmission paths and arbitrate any communication issues.Type: GrantFiled: September 20, 2005Date of Patent: April 27, 2010Assignee: Lockheed Martin CorporationInventors: Rick C. Stevens, Gregory J. Whaley, Brian S. Leininger

Patent number: 7512237Abstract: A multiplexing technique for optical communications used to create a pseudo-random communications signal in the optical domain such that only the sender and/or receiver can decode the signal. The multiplexing technique may include one or more information-bearing optical signals combined with one or more dynamic pseudo-randomly-generated optical signals to create a combined dynamic subcarrier multiplexed privacy-protected output signal. The information-bearing signal is protocol-independent and can be of mixed type, such as RF, analog, and/or digital. Only the receiver of the privacy-protected signal may decode the pseudo-random signal so as to disclose the information-bearing signal. The present invention may use dynamic subcarrier multiplexing selection based on standard digital encryption and the use of optical range time to ensure synchronization.Type: GrantFiled: October 26, 2004Date of Patent: March 31, 2009Assignee: Lockheed Martin CorporationInventors: Howard J.
