Booster Amplifier shows the characterization of a booster/power amplifier setup in a single erbium-doped fiber stage heavily doped, bidirectionally pumped by two 980 nm pump lasers. A large signal input power is considered in this case, since high signal input helps to produce high output power, which is necessary to booster/power amplifiers. As a consequence, moderate gain will be observed in this case. The low noise figure requirement of EDFAs is not so critical in this case, because an increase in NF can be tolerated. It is important to mention that typical configurations of booster amplifiers include multiple Er-doped fiber stages.
