Design of a Double-Pass L-Band Erbium Doped Fiber Amplifier (L-EDFA)

In this study, the design and experimental characterisation of a bidirectionally pumped double-pass L-band EDFA is realized. First, the performance parameters of the double-pass L-band EDFA design are theoretically analyzed using Optiamplifier 4.0 simulation program. Then, it is realised experimentally and, its gain and noise figure performances are characterized and compared with the classical single-pass L-EDFA design.
