Optical Communications Networks Utilizing Frequency Division Multiplexing

View page
US Patent:
6529303, Mar 4, 2003
Filed:
Sep 24, 1999
Appl. No.:
09/405367
Inventors:
Michael W. Rowan - Los Gatos CA
David B. Upham - Sunnyvale CA
Augustus Elmer - San Jose CA
Laurence J. Newell - Saratoga CA
David A. Pechner - San Jose CA
Abraham Kou - San Jose CA
James F. Coward - La Honda CA
Norman L. Swenson - Mountain View CA
Minnie Ho - Palo Alto CA
Peter H. Chang - San Jose CA
Ting K. Yee - Foster City CA
Stuart E. Wilson - Menlo Park CA
Assignee:
Kestrel Solutions, Inc. - Mountain View CA
International Classification:
H04J 1402
US Classification:
359128, 359127, 359189, 370480
Abstract:
A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels and electrical low-speed channels. The FDM node includes a high-speed system and an ADM crosspoint. The high-speed system converts between an optical high-speed channel and its constituent electrical low-speed channels through the use of frequency division multiplexing and preferably also QAM modulation. The ADM crosspoint couples incoming low-speed channels to outgoing low-speed channels, thus implementing the ADM functionality for the FDM node.

Control Channel For An Optical Communications System Utilizing Frequency Division Multiplexing

US Patent:
20020024694, Feb 28, 2002
Filed:
May 11, 2001
Appl. No.:
09/853556
Inventors:
Laurence Newell - Saratoga CA, US
David Pechner - San Jose CA, US
Augustus Elmer - San Jose CA, US
David Upham - Sunnyvale CA, US
International Classification:
H04J014/02
US Classification:
359/124000
Abstract:
Overhead information is transmitted from a first node to a second node in an optical fiber communications system using a separate frequency band. A control channel containing the overhead information is frequency division multiplexed with electrical low-speed channels to form an electrical high-speed channel, which is converted from electrical to optical form to form an optical high-speed channel. The optical high-speed channel is transmitted over the optical fiber to the second node. In one embodiment, the control channel has a narrow bandwidth and/or is located at lower frequencies than the electrical low-speed channels, thus making the control channel more robust to impairments in the optical fiber.

US Patent:
6452945, Sep 17, 2002
Filed:
Jan 13, 1999
Appl. No.:
09/229594
Inventors:
David B. Upham - Sunnyvale CA
Augustus Elmer - San Jose CA
Laurence J. Newell - Saratoga CA
David A. Pechner - San Jose CA
Abraham Kou - San Jose CA
Michael W. Rowan - Los Gatos CA
James F. Coward - La Honda CA
Norman L. Swenson - Fremont CA
Minnie Ho - Palo Alto CA
Assignee:
Kestrel Solutions, Inc. - Mountain View CA
International Classification:
H04J 308
US Classification:
370480, 370535
Abstract:
A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels, and low-speed tributaries. The FDM node includes a high-speed system and an ADM crosspoint. The high-speed system converts between an optical high-speed channel and its constituent electrical, low-speed channels through the use of frequency division multiplexing. The ADM crosspoint couples any incoming low-speed channels and any incoming tributaries to any outgoing low-speed channels and tributaries, thus implementing the ADM functionality for the FDM node.
