ABSTRACT:
The optical amplifier realizes EDFA amplification of optical signals in new bands (the S+- and S-bands), at wavelengths of 1450 to 1530 nm. The amplifier uses multiple erbium-doped fibers to amplify optical signals at wavelengths of 1450 to 1530 nm. Each of the multiple optical filters is interposed between the individual erbium-doped fibers. The sum of the transmission characteristics of the multiple filters is identical to an inverted EDF wavelength gain characteristic at wavelengths of 1450 to 1530 nm which is then shifted to the direction that the transmission increases.
