1. An optical amplifier, comprising:

  • a distributed Raman amplifier that includes a signal transmission line wherein at least a portion of the signal transmission line comprises a distributed gain medium for the distributed Raman amplifier;

    a WDM coupled to the signal transmission line;

    a discrete Raman amplifier coupled in series to the WDM and the distributed Raman amplifier; and

    a pump source coupled to the WDM and producing a pump beam λ

    p at wavelengths less than 1400 nm;

    wherein a majority of signal wavelengths received by each of the distributed Raman amplifier and the discrete Raman amplifier are also received by the other of the distributed Raman amplifier and the discrete Raman amplifier; and

    wherein at least a portion of the signal transmission line comprises a zero dispersion wavelength λ

    0, and wherein λ

    p is within thirty (30) nanometers of λ

    0.
