A theoretical study of transient behavior of gain-clamped erbium doped fiber amplifiers in WDM systems

We present a detailed theoretical analysis of the transient behaviors of erbium doped fiber amplifiers (EDFA's) in wavelength division multiplexed (WDM) optical networks by using a single dynamic model. While the amplifier is longitudinally divided into n subsections to take into account the longitudinal spatial hole-burning, and fully resolved amplified spontaneous emission (ASE) spectra. The tradeoff between accuracy and computational …
