摘要： A fiber amplifier suitable for high power, narrow linewidth applications exhibits suppression of stimulated Brillouin scattering (SBS) by segmenting the fiber amplifier into separate portions that exhibit different Brillouin center frequencies. By changing the center frequencies in adjoining segments of the fiber amplifier, the backward-propagating Stokes signal is essentially blocked, and SBS is suppressed. In a preferred embodiment the segmentation is added to the terminating portion of the fiber amplifier. Various techniques, including temperature modifications, can be used to impart the desired center frequency shift.

摘要： The specification describes a distributed Raman amplifier with multiple pump sources for wide band amplification of wavelength division multiplexed (WDM) signals. It was recognized that using multiple pump sources introduces non-linear effects, such as four wave mixing (FWM). These effects are reduced by multiplexing the pump wavelengths in the multiple pump source. It was also recognized that not all of the pump wavelengths over the wavelength spectrum of the pumps contributes to FWM. Thus fewer than all of the pump wavelengths require multiplexing to eliminate FWM in the multiple wavelength pump source. Various approaches are described to ensure that the pump wavelengths do not interact in FWM in the transmission span. The selected individual pump wavelengths may be either time division multiplexed, or frequency modulated.
摘要翻译：该规范描述了具有多个泵浦源的分布式拉曼放大器，用于波分复用（WDM）信号的宽带放大。已经认识到，使用多个泵浦源引入非线性效应，例如四波混频（FWM）。通过多泵泵浦波长在多泵浦源中减少这些影响。还认识到，不是所有泵浦波长在泵的波长谱上都有助于FWM。因此，比所有的泵浦波长要少的复用以消除多波长泵浦源中的FWM。描述了各种方法以确保泵浦波长在传输跨度中不与FWM相互作用。所选择的单个泵浦波长可以是时分复用的或频率调制的。
