Minimum Input Power of Optical Amplifier
The minimum input power specified for an Erbium-Doped Fiber Amplifier (EDFA) to achieve its characteristic small signal gain is -20 dBm. Booster (power) amplifiers: Boost power into transmission fiber, low NF, high Psat. An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. Typically, inputs and outputs are laser beams (very rarely other types of light beams), either propagating as Gaussian beams in free space or in a fiber.
