Disclosed are an optical fiber coupling system and method. The system comprises an optical coupler (110), a first optical power detector (PD) (120), an input optical fiber (130) and a first adjustment platform (140); the optical coupler (110) is used to transmit incident light input via a first input port (111) to the input optical fiber (130) via an output port (113); the input optical fiber (130) is used to transmit the incident light to an input optical waveguide coupler, and transmit to the output port (113) reflected light reflected from the input optical waveguide coupler; the optical coupler (110) is also used to output the reflected light via the first input port (111) and a second input port (112); the first optical PD (120) is used to detect an optical power of the reflected light output via the second input port (112); and the first adjustment platform (140) is used to adjust the position of the input optical fiber (130) according to the optical power of the reflected light.
