ABSTRACT:
An optical fiber amplifier capable of compensating dispersion and loss of an optical signal in transmission along an optical fiber includes an optical fiber doped with erbium ions and having a dispersion compensating function. The amplifier further includes an erbium pump for performing forward pumping to the optical fiber, and a Raman pump for performing backward pumping to the optical fiber which is forward-pumped by the erbium pump means. When an optical signal passes through the optical fiber which undergoes density inversion of erbium ions and Stimulated Raman Scattering (SRS), dispersion and loss of the optical signal is compensated.
