Abstract
Optical amplifier equipment is provided for wavelength-division-multiplexing optical communications links that support multiple channels operating at different wavelengths. The optical amplifier equipment may be based on distributed or discrete Raman amplifiers, rare-earth-doped fiber amplifiers such as erbium-doped fiber amplifiers, or other suitable amplifiers. Optical signals on the link may be monitored using optical monitoring equipment. The optical power of the signals on a particular channel or channels that are always present on the link may be measured. The total power of the optical signals may also be measured. The pump power in the amplifier equipment may be adjusted to suppress gain transients. The pump power may be adjusted based on the measured power of the guaranteed signals. Pump power may also be adjusted based on the measured total power.
