What is a fiber amplifier?

Fiber amplifiers (fibre amplifiers, fiber optic amplifiers, or fiber laser amplifiers) are optical amplifiers utilizing an optical fiber doped with some rare earth element as the active gain medium, allowing power amplification of an optical signal from a pump laser, for cost-effective light amplification of a low input power laser, or to boost attenuated signal traveling long distances, for example.
