    摘要： Optical transmission systems of the present invention include at least one optical amplifier generally including an optical signal amplifying medium supplied with pump power in the form of optical energy in via an optical pump source. The pump source includes multiple optical sources, at least two of which provide optical energy in first and second wavelength ranges separated by a frequency difference. The amplifier includes a wavelength controller configured to adjust the wavelength range of at least one of the optical sources to vary the frequency difference in a manner sufficient to vary optical intensity noise produced when the optical energy from the multiple optical sources is combined.

    摘要翻译： 本发明的光传输系统包括至少一个光放大器，通常包括经由光泵浦源以光能形式提供泵功率的光信号放大介质。 泵浦源包括多个光源，其中至少两个光源在由频率差分开的第一和第二波长范围内提供光能。 放大器包括波长控制器，其被配置为调整至少一个光源的波长范围，以以足以改变当来自多个光源的光能被组合时产生的光强度噪声的方式改变频率差。
