Abstract:The Gain flatness of EDFA plays an important role for Wavelength Division Multiplexing (WDM) optical application. Equalizing of an amplifier's gain spectrum is essential for balancing the channel powers to achieve error free detection of the signals transmitted through the optical link. The purpose of this paper is to improve the gain unevenness for each channel in order to equalize the amplitude in a Wavelength Division Multiplexing (WDM) system. And also various filters have been taken under study to find it… Show more
