Matisse Networks Awarded Patent for Optical Burst Receiver

Wednesday, January 14, 2009

Mountain View, CA -- Matisse Networks, pioneer in the field of optical burst switching (OBS) and the unique EtherBurst packet WDM system, announced today that 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. 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' Chief Operating Officer. Hamou continued, "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 the field of Optical Burst Switching (OBS). The earlier patents issued to Matisse 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 10Gbps 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.
