Abstract: In an optically amplified multi-wavelength optical fiber communication system (e.g., 80), deleterious effects due to channel addition/removal can be reduced or avoided if the optical amplifiers (80) are "overpumped", that is to say, the system is selected such that at least 70%, preferably 90% or more, of the pump power that is introduced into the amplifier fiber is unabsorbed in the amplifier fiber.
