Patent number: 8401385Abstract: A large communication network suitable for nationwide or worldwide utilization. The present invention overthrows the conventional packet switching technologies with an all-optical network. The invention uses tunable laser sources to generate large number of highly stable narrow-band optical signals, each serving as a communication channel. With packet processing replaced by all-optical channels, the network become highly secure and scalable while harnessing the virtually unlimited capacity of fiber-optic. A large number of nodes (called area code nodes) are connected with all-fiber-optic links with all-optical switches. A routing algorithm provides one or more communication links from each area code node to every other area code node so that information never has to change carrier wavelength as it travels the network. Each area code node contains circuits that are provided to connect individual users to the network.Type: GrantFiled: December 17, 2009Date of Patent: March 19, 2013Assignee: Trex Enterprises Corp.Inventors: Brett Spivey, Eric Korevaar, Hus Tigli, Todd Barrett
