Abstract
WDM networks use wavelength-selective add/ drop multiplexing (ADM) to achieve significant enhancements in efficiency, flexibility, and throughput. Since L-band transmission is becoming commercially available, optical ADM operations will be required for both the L and C bands. However, whenever channels are dropped or added, the system performance is adversely affected by the power transients of single and cascaded erbium-doped fiber amplifiers (EDFA).
