METHOD OF CONFIGURING AN OPTICAL COMMUNICATION NETWORK CONFIGURED FOR CO-PROPAGATING RAMAN AMPLIFICATION AND AN OPTICAL COMMUNICATION NETWORK ELEMENT

摘要

A method includes: selecting an optical pump signal power of a Raman amplifier such that a saturated gain of the Raman amplifier is at a maximum operating level without exceeding a gain threshold above which an optical signal to noise ratio penalty is no longer negligible in the Raman amplifier; selecting an optical signal power for at least one optical communication signal to be transmitted across the optical link to maximise a Q-factor of the optical signal when the Raman amplifier is configured for said maximum operating level of the saturated gain; generating a pump signal power control signal to cause an optical pump signal source of the Raman amplifier to generate an optical pump signal having the selected optical pump signal power; and 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.

1. A method 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; 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; 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; 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.
