Raman threshold pump power and optical amplification band calculations
 adjusted for attenuation dispersion in the range of total S+C+L telecom window of silica
 fibers (roughly from 1.46 to 1.62 μm) are presented. It has been shown that wavelength
 nonuniformity of signal attenuation coefficient essentially effects on amplification
 bandwidth and leads to the bandwidth decrease from 0.9 to 2.5 THz depending on a
 pump spectral position and fiber type. Offered has been the technique of analytical
 approximation of attenuation coefficient as a basis for pump power threshold
 determination and for preceding data correction with reference to an optical amplification
 band. Simulation results for three widely used fibers, namely, DCF, TrueWaveRS™ and
 SMF have been presented. However, the technique allows estimating the optimal pump
 power in fiber Raman amplifiers for other fiber types as well.
