  • System and method for gain equalization and optical communication system incorporating the same
    Patent number: 7924497
    Abstract: An optical amplifier including gain equalization and system incorporating the same. The amplifier includes a Raman portion and an EDFA portion with a gain flattening filter coupled between the Raman portion and the EDFA.
    Type: Grant
    Filed: September 21, 2006
    Date of Patent: April 12, 2011
    Assignee: Tyco Electronics Subsea Communications LLC
    Inventors: Morten Nissov, Alexei N. Pilipetskii, Alan J. Lucero
  • Dispersion management in optical networks using a differential phase shift keying modulation format
    Patent number: 7734187
    Abstract: Dispersion may be managed in an optical network configured to transmit differential phase shift keying (DPSK) modulated signals by allowing accumulation of dispersion to thousands of ps/nm before compensating. A dispersion map providing a negative average dispersion and a minimum dispersion wavelength outside of the signal band may be employed.

  • Wavelength division multiplexing systems
    Patent number: 6674557
    Abstract: A long haul, broadband DWDM system that has been optimized by the proper selection of the distribution of total dispersion compensation. Dispersion compensation is utilized at both the receiver and transmitter ends. System performance is dependent on the ratio of compensation split between the transmitter and the receiver. A system operated in the nonlinear regime can be compensated to operate with low BER and with reduced penalties due to residual dispersion effects, even when the spread of total accumulated dispersion between the extreme channels in a broadband system exceeds 1,100 ps/nm.
