Abstract :
The erbium doped fiber amplifier (EDFA) is a key enabler of WDM transmission systems and wavelength routed optical networks. EDFAs are well suited to compensate the optical loss of network elements and transmission spans. Although the EDFA´s are almost ideal in their characteristics, they are not quite perfect. Two effects which are critical in WDM networks and transmission systems are spectral gain non-uniformity and channel cross saturation in EDFAs.
