RAMAN Optical Fiber Amplifiers
Series of Raman amplifiers (RA) up to 1 W for building extended communication lines in the C-band (1529 – 1561 nm)
• configurations in the form of a one-section or two-section amplifier
• preservation of channel gain when changing the number of channels
• low noise factor
• low non-uniformity of the amplification spectrum in the C-band
• modes gain stabilization for RA with counter-pumping
Characteristics of the Raman amplifier:
• has 4 laser pump diodes with a total power of 1 W, which makes it possible to achieve low spectral gain non-uniformity and effective noise factor
• has configurations with back and forth pumping and is used in lines with long spans
• used to increase the length of the span between erbium amplifiers
