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 length of erbium-doped fiber for different input power, and meanwhile pump power is regulated, so good adaptivity for different applications can be obtained. Simulation experiments have demonstrated that this amplifier can get high performance. It can...
