Abstract
A method and a device for determining an input optical power are provided. The method include: after determining a bias current value of an optical amplifier unit when the optical amplifier unit amplifies a target optical signal and a voltage value output after an optical receiving unit converts the amplified target optical signal into an electrical signal, determining, according to a predetermined first correspondence that is among a bias current value, a voltage value, and an input optical power value and corresponds to a wavelength of the target optical signal, an input optical power value corresponding to the determined bias current value and the determined voltage value. By using the solution in the embodiments of the present invention, an input optical power of an optical signal on which optical amplification is performed can be determined.
