Abstract
Distributed Raman amplifier systems are provided in which gain transients are controlled. Signal taps may be used to monitor optical signal powers at network nodes. A telemetry channel may be used to share information between nodes. Information on the output power of a given node may be passed to a subsequent node using the telemetry channel. The subsequent node may use feed-forward and feedback control schemes to control Raman gain transients in the preceding transmission fiber span based on the output power information received over the telemetry channel.
