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.

Abstract translation: 在光放大的多波长光纤通信系统（例如，80）中，如果光放大器（80）“过度抽取”，则可以减少或避免由于信道添加/去除引起的有害影响，也就是说，系统是 被选择为使得放入到放大器光纤中的泵浦功率的至少70％，优选地为90％或更多，在放大器光纤中未被吸收。
