ANDOVER, Mass. -- Quantum Bridge Communications, Inc., a leading developer of optical access networking solutions, today announced that it has been issued US patents for the recovery of burst mode data in distributed media systems. The patents, #6,122,335, #6,269,137 and #6,420,928, are key to the efficient transport of upstream data in a Passive Optical Networks (PON) and allow Quantum Bridge to continue its leadership position in high performance, high speed, scalable Ethernet PON (EPON) and ATM PON (APON) systems. "The greatest challenge in developing any distributed media system, such as a PON, is the reliable and efficient reception of signals at the Optical Line Terminal. The keys to this are the ability to receive information from Optical Network Units at any distance from the Optical Line Terminal and to do it at line speed," said Jeffrey Masucci, Quantum Bridge's Senior Vice President of Engineering. "These patents allow Quantum Bridge to scale the PON line rates beyond 622 Mbps and efficiently carry voice, video and data services." For service providers, this breakthrough means that an access network can be implemented with PON solutions that can transport Ethernet, ATM and TDM traffic with scalable line PON line rates.
