A method 10 of configuring an optical communication network comprising an optical link comprising an optical fibre configured as a Raman amplifier configured for co-propagating Raman amplification, the method comprising: a. selecting an optical pump signal power, Pp, of the Raman amplifier such that a saturated gain, G, of the Raman amplifier is at a maximum operating level without exceeding a gain threshold above which an optical signal to noise ratio penalty caused by double Rayleigh scattering is no longer negligible in the Raman amplifier 12; b. selecting an optical signal power, Pch, for at least one optical communication signal to be transmitted across the optical link, the optical signal power being selected to maximise a Q-factor of the optical signal when the Raman amplifier is configured for said maximum operating level of the saturated gain 14; c. generating a pump signal power control signal configured to cause an optical pump signal source of the Raman amplifier to generate an optical pump signal having the selected optical pump signal power 16; and d. generating a signal power control signal configured to cause the optical communication signal to be delivered into the optical link at the selected optical signal power 18. |
