Abstract :
We present results on spectral gain changes resulting from small changes of pump wavelength in erbium-doped fiber amplifiers (EDFAs). While conventional-band EDFAs exhibit a significant effect with 980-nm pumping and a smaller effect with 1480 nm, it is absent for extended-band EDFAs operating around 1585 nm.
