摘要： An optical fiber transmission link with reduced channel depletion due to stimulated Raman scattering is formed by including a high pass optical filter in the transmission fiber. The filter may comprise one or more discrete components, or may be formed as a “distributed” filter along the length of the optical fiber. The cut-off frequency for the high pass optical filter is selected to be immediately below the frequency of the input channel to be transmitted. When used in an arrangement with multiple input channels, the cut-off frequency is controlled to be immediately below the lowest input channel frequency.

摘要： A fiber Raman amplifier with increased gain and improved pump conversion efficiency is formed by including a high pass optical filter in the amplifier structure. The filter may comprise one or more discrete components, or may be formed as a “distributed” filter along the length of the fiber amplifier. The cut-off frequency for the high pass optical filter is selected to be immediately below the frequency of the input signal to be amplified. When used in an arrangement with multiple input signals, the cutoff frequency is controlled to be immediately below the lowest input signal frequency.
