Gain, Noise Figure and Efficiency Characteristics of an L-Band Erbium Doped Fiber Amplifier

2. L-Band Edfa Measurement System

The single coil L-band EDFA constructed for investigating the gain and noise figure characteristics of Er³⁺-doped fiber coil as function of 1480 nm pumping schemes and power levels is shown schematically in Figure 1. The Er³⁺-doped fiber coil key specifications are listed in Table 1.
