Abstract
An erbium doped fiber amplifier (EDFA) suitable for amplifying a long wavelength light signal in the range in the 1570 to 1610 nm band, includes a pump light source for generating pump light in the 980 or 1480 nm band, a light coupler for receiving the pump light from the pump light source and coupling the same to the received light signal, first and second optical fibers doped with erbium ions, for amplifying the received light signal by the pump light, and an isolator positioned at a point between the first and second erbium doped optical fibers (EDFs). The gain and noise figure of the EDFA for amplifying received light signal in a long wavelength band can be improved. Also, an EDFA suitable for amplifying received light signal in the 1570 to 1610 nm band can be attained.
