JANUARY 13, 2009 -- Matisse Networks says it has been awarded a patent (U.S. Patent No. 7,436,920 B2) on optical burst receiver technology that provides key functionality for optical burst switching. Matisse uses optical burst switching as part of its EtherBurst packet WDM system. The patent covers an innovation on receiving optical burst transmissions using a charge pump PLL with loop stabilization to improve the reliability and performance of the receive function of the optical burst transponder.
"This patent is an important achievement for Matisse, as it protects a part of the core intellectual property in our EtherBurst optical burst switching solution," said Claude Hamou, Matisse Networks' COO. "We've made a significant breakthrough in optical burst technology that has broad applicability in WDM optical transport networks and other applications."
The patent is the latest of a number of patents have been awarded to Matisse for innovations in OBS. The earlier patents cover innovations including synchronization of burst transmitters and bandwidth reservation capabilities within the optical burst network domain. This latest patent pertains to technology that enables reliably receiving optical burst traffic. Currently, Matisse uses the technology in its 10-Gbps eBurst optical burst module. The eBurst module is a core component of the EtherBurst SX-1000 switch node which supports a variety of telecommunication services and enterprise applications.
