Patent number: 8462626Abstract: The present system uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.Type: GrantFiled: August 20, 2007Date of Patent: June 11, 2013Assignee: Ciena CorporationInventors: Gautam Desai, Subrahmanyam Dravida, Satya V.

Publication number: 20080056130Abstract: Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router.Type: ApplicationFiled: August 20, 2007Publication date: March 6, 2008Inventors: Gautam Desai, Subrahmanyam Dravida, Satya Gupta, Kiran Rege, Manas Tandon, Ravi Kumar, DeQuan Wu
