Abstract
A L-band(long-band) optical fiber amplifier is provided. The L-band optical fiber amplifier includes an optical fiber doped with a rare-earth element, at least one pumping light source for emitting pumping light to the optical fiber, a seed beam source for emitting a seed beam at a predetermined wavelength band, and a seed beam coupler disposed between an input terminal and the optical fiber, for coupling an input optical signal with the seed beam and feeding the coupled light forward to the optical fiber. By use of the seed beam, the L-band optical fiber amplifier improves gain flatness characteristics at wavelengths of an optical signal and increases amplification efficiency when the length of the optical fiber and the intensities of the optical signal and the pumping light are changed.
