  • Method and apparatus for determining maximum gain of Raman fiber amplifier
    Patent number: 11251871
    Abstract: The present disclosure relates to a technical field of optical communication, and provides a method and an apparatus for determining maximum gain of Raman fiber amplifier. Wherein the method includes obtaining transmission performance parameters of a current optical fiber transmission line; respectively obtaining impact factors A1, A2, A4 according to a distance between a joint and a pump source, a fiber loss coefficient, and a fiber length included in the transmission performance parameters; calculating a joint loss value AttAeff according to a distance between a joint and a pump source, a fiber loss coefficient, and looking up impact factor A3 according to AttAeff; determining an actual maximum gain which may actually be achieved by the Raman fiber amplifier according to A1, A2, A3, A4.
