In this paper, EYDWA (erbium ytterbium doped waveguide amplifier) is characterized for a wavelength division multiplexed (WDM) system operating in C+L bands with channels being spaced at 0.4 nm interval. In order to analyze the gain characteristic of EYDWA, two pumping configurations: co-propagating and counter propagating have been used. The system is analyzed on the basis of gain and noise figure at different pumping powers in wavelength range of 1540 nm to 1579.6 nm and with pumping wavelength of 970 nm. The waveguide parameters (such as doping concentration, waveguide length) and pump power are optimized in order to obtain overall enhanced gain spectra in this paper and some useful results are obtained by employing two pumping configurations i.e. counter and co-propagating pumping.
