Abstract
A new adaptive erbium-doped fiber amplifier (EDFA) is proposed. In the amplifier, an array of 1×2 optical switches is controlled to select the optimum erbium-doped fiber length for different input power, and meanwhile pump power is regulated. Simulation experiments have demonstrated that this amplifier can get good adaptability.
