Wdm Optical Communication Network With Data Bridging Plural Optical Channels Between Optical Waveguides
View pageUS Patent:
20020075538, Jun 20, 2002
Filed:
Dec 8, 2000
Appl. No.:

International Classification:
H04J014/02
US Classification:
359/124000, 359/127000
Abstract:
The present invention relates to an optical network including a bridge for selectively transferring information from an optical channel carried on a first WDM optical waveguide to at least two optical channels on a second WDM optical waveguide. The first and second optical waveguides carry WDM optical signals each having plural optical channels. A bridge is interposed between the first and second optical waveguides which includes an optical add-drop multiplexer optically communicating with each waveguide. At least one optical channel having first and second data bits streams is dropped from the first waveguide. The first and second data bit streams are respectively encoded on two different optical channels which are then added to the second optical waveguide.
Bidirectional Wdm Optical Communication System With Bidirectional Optical Service Channels

H04J014/00
US Classification:
385/024000, 359/118000, 359/173000
Abstract:
The present invention provides a bidirectional wavelength division multiplexed optical communication system having bidirectional optical service channels. The bidirectional WDM optical communication system includes a bidirectional optical waveguide configured to carry a bidirectional optical communication signal comprising counterpropagating WDM optical signals. Each WDM optical signal includes plural optical channels and an optical service channel. A bidirectional optical add-drop multiplexer optically communicates with the waveguide. A first optical service channel selector optically communicates with the first bidirectional optical add-drop multiplexer input/output port. The first optical service channel selector is configured to separate the first optical service channel from the first WDM optical communication signal such that the first WDM signal enters the first input/output port of the bidirectional optical add-drop multiplexer and the first optical service channel is routed to a service channel module. Similarly, a second optical service channel selector optically communicates with the second input/output port of the bidirectional optical add-drop multiplexer and routes the second optical service channel to a service channel module. The bidirectional WDM optical communication system may advantageously by deployed in metropolitan networks requiring high volumes of add-drop multiplexing.

Assignee:
Seneca Networks - Rockville MD
International Classification:
H04B 1000
H04B 1002
H04B 1002
US Classification:
359127
Abstract:
The present invention provides a flexible WDM optical communication system in which each optical channel of the WDM optical communication signal can simultaneously accept multiple data formats. In one embodiment, the WDM optical system includes an optical waveguide having an optical add-drop multiplexer to selectively add and/or drop one or more optical channels to/from the WDM signal carried on the waveguide. A first source of data imparts information onto a first optical channel in a packet format while a second source of data imparts information onto the first optical channel in a time division multiplexed format. Other data sources having other data formats may also be included. An optical network interface electrically communicates with the data sources, placing the data from these sources onto the first optical channel which is generated from an optical source such as a laser. An optical path carries the optical channel from the optical source to the optical add-drop multiplexer.
Protection Switching In Bidirectional Wdm Optical Communication Networks With Transponders
View pageUS Patent:
63079860, Oct 23, 2001
Filed:
Apr 24, 2001
Appl. No.:
9/840043
Inventors:
Gary Duerksen - College Park MD
John Lynn Shanton - Middletown MD
John Lynn Shanton - Middletown MD
Assignee:
Seneca Networks - Rockville MD
International Classification:
G02B 628
US Classification:
385 24
Abstract:
The present invention provides a system for protection switching in a wavelength division multiplexed optical communication network including optical transponders within optical nodes. A work optical transponder receives a first work optical channel dropped by an optical add-drop multiplexer from an optical waveguide while a second work optical transponder adds a work optical channel to the optical add-drop multiplexer. Similarly, a first protect optical transponder is positioned to receive a protect optical channel dropped by the optical add-drop multiplexer while a second protect optical transponder is positioned to add a protect optical channel to the optical add-drop multiplexer. A detection element detects the strength of the optical channel received by the first work optical transponder; control means responsive to the means for detecting the strength of the optical channel received by the first optical transponder, the control means activating the second protect transponder and inactivating the second work transponder when the strength of the optical channel received by the first optical transponder falls below a preset level.

US Classification:
359124
Abstract:
A WDM system carrying a plurality of optical signals, each at a respective wavelength, is provided whereby each optical signal includes a plurality of frames, each frame conforming to a synchronous optical network (SONET) standard. A plurality of optical transmitter modules output a corresponding one of the plurality of optical signals, and each of a plurality of optical selector at a receiving end of the WDM system selects a respective one of the plurality of optical signals. In addition, a plurality of receiver modules are provided respectively connected to each of the optical selectors. Both the transmitter and receiver modules include byte extraction circuitry that extracts one byte, e. g. , the J0 byte, from each of the plurality of frames. Successive bytes are grouped as messages, which are stored in registers so that comparisons can be made between consecutive messages and a predetermined message.
Protection Switching In Bidirectional Wdm Optical Communication Networks

John Lynn Shanton - Middletown MD
Assignee:
Seneca Networks - Rockville MD
International Classification:
G02B 628
US Classification:
385 24
Abstract:
The present invention provides a bidirectional wavelength division multiplexed optical communication network having a protection switching capability within a bidirectional optical waveguide. A bidirectional optical waveguide having plural optical nodes carries counterpropagating wavelength division multiplexed optical communication signals: M optical channels in a first direction and N optical channels in a second direction. The network includes the capacity to generate X+Y protect optical channels which respectively propagate in the first and second directions. Upon detecting loss of an optical signal means are provided for switching the affected M work optical channels to the Y protect optical channels and the affected N work channels to the X protect channels. In this manner, protection switching may be accomplished in a bidirectional optical network on a single bidirectional optical waveguide.
