Abstract
A method and apparatus for amplifying the optical signals of a C-band (1550 nm wavelength band) and a L-band (1580 nm wavelength band) in a wide-band optical fiber amplifier, wherein the incoming optical signals are separated into the 1550 nm wavelength band and the 1580 nm wavelength band by a WVDM optical coupler and respectively amplified by a C-band EDFA and a L-band EDFA A backward ASE generated by the C-band EDFA is fed back to the L-band EDFA by a circulator as a supplementary pumping light to the amplification of the optical signals of the 1580 nm wavelength band.
