Abstract: An optical signal detection apparatus. The apparatus includes an optical-to-electrical conversion module, a control module, a gain adjustment module, and an analog-to-digital conversion module. The optical-to-electrical conversion module is configured to receive an optical signal, and convert a received optical signal into an electrical signal; the control module is configured to obtain a first gain value corresponding to a first detection time period, the first detection time period is a detection time period in the detection cycle, different detection time periods in the detection cycle correspond to different gain values, and the first gain value is used for controlling the gain adjustment module to adjust an amplitude of the electrical signal; and the analog-to-digital conversion module is configured to perform sampling on an adjusted electrical signal, where the adjusted electrical signal is in a sampling range of the analog-to-digital conversion module.
