EDFA Optical Fiber Amplifiers
Series of erbium amplifiers (EA) 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
• output power and gain stabilization modes for EA
Characteristics of the erbium amplifier:
• has a flexible and fast adjustment to changes in the configuration of fiber-optic communication lines and is widely used in backbone, regional and metro networks
• works in a wide range of input and output powers and has the ability to adjust the gain
• has a low noise factor and low spectral non-uniformity
