Patent Number Title Of Patent Date Issued
7974002 System and method for managing system margin July 5, 2011
An optical communication system is operable to communicate a plurality of wavelength signals at a bit rate of at least 9.5 gigabits per second over a multiple span communication link spanning at least 400 kilometers without optical regenerators. The plurality of wavelength signals includ
7254337 Band optical add/drop multiplexing August 7, 2007
An optical communication system includes a plurality of optical add/drop multiplexers (OADMs). The plurality of OADMs includes at least five low distortion OADMs. Each OADM is coupled between spans of a multiple span communication link and operable to receive a multiple wavelength signal
7197245 System and method for managing system margin March 27, 2007
An optical communication system is operable to communicate a plurality of wavelength signals at a bit rate of at least 9.5 gigabits per second over a multiple span communication link spanning at least 400 kilometers without optical regenerators. The plurality of wavelength signals includ
7075927 Method and system for quality of service (QoS) support in a packet-switched network July 11, 2006
A method and system for transporting traffic having disparate qualities of service classes across a packet-switched network includes receiving at an ingress node of a network a plurality of packets each comprising a quality of service (QoS) class defined externally to the network. Packet
7068938 Band optical add/drop multiplexing June 27, 2006
An optical communication system includes a plurality of optical add/drop multiplexers (OADMs). The plurality of OADMs includes at least five low distortion OADMs. Each OADM is coupled between spans of a multiple span communication link and operable to receive a multiple wavelength signal
6744553 System and method for converting a plurality of wavelengths June 1, 2004
In one aspect of the invention, an apparatus operable to convert wavelengths of a plurality of optical signals includes a coupler operable to receive a pump signal and a plurality of input signals each input signal comprising at least one wavelength different than the wavelengths of
6693909 Method and system for transporting traffic in a packet-switched network February 17, 2004
A method and system for transporting traffic in a packet-switched network segments high priority pass-through traffic from low priority pass-through traffic. The high priority pass-through traffic is transmitted on an egress link preferentially over the low priority pass-through traffic
6646788 System and method for wide band Raman amplification November 11, 2003
A multi-stage Raman amplifier includes a first Raman amplifier stage having a first sloped gain profile operable to amplify a plurality of signal wavelengths, and a second Raman amplifier stage having a second sloped gain profile operable to amplify at least most of the plurality of sign
6587259 System and method for controlling noise figure July 1, 2003
One aspect of the invention includes an optical amplifier operable to amplify a plurality of optical wavelength signals at least in part through Raman amplification. The amplifier includes an input operable to receive a plurality of wavelength signals and an output operable to communicat
6532101 System and method for wide band Raman amplification March 11, 2003
A multi-stage Raman amplifier includes a first Raman amplifier stage having a first sloped gain profile operable to amplify a plurality of signal wavelengths, and a second Raman amplifier stage having a second sloped gain profile operable to amplify at least most of the plurality of sign
