A simple technique for modeling transients in erbium-doped fiber amplifiers (EDFA's) has been applied to a gain-clamped amplifier. Integration of the variables along the length of the amplifier allows the formulation of the problem as a single simple, ordinary, time-dependent differential equation. We demonstrate examples for a typical conventional EDFA and one in which internal out-of-band oscillation is used to clamp the gain.
