In this work, the construction of a single stage L-band erbium-doped fiber amplifier which incorporates a short 5.1 m erbium doped fiber coil is described. Gain and noise figure measurements as a function of forward, backward and counter-propagating CW 1480 nm pumping schemes at different pump power levels are presented. Further, the Erbium Doped Fiber Amplifier (EDFA) power conversion efficiency (PCE) calculations as a function of pump power are provided.
