Erbium-doped fiber line amplifier (LA, In-Line Amplifier) is an optical power amplifier product dedicated to line relay in fiber laser or fiber communication systems. It combines the advantages of PA amplifier and BA amplifier, with high gain, high transmit power, the advantage of relatively low noise is used between fiber sections to increase the length of the relay or in the corresponding single-to-multipoint part of the optical access network to compensate for branch loss.
