Abstract
The present invention discloses an optical module and a detection circuit thereof. The detection circuit includes: a sampling module, including a first potentiometer configured to convert a sampling current into a sampling voltage; an amplifying module, coupled to an output end of the sampling module and configured to amplify the sampling voltage; and an analog-to-digital conversion module, coupled to an output end of the amplifying module and configured to convert the amplified sampling voltage into a digital signal for detection. By arranging a potentiometer in a sampling module of a detection circuit, a resistance value of the sampling module can be adjusted, thereby adapting to responsivities of different modulators, increasing the locking speed of a modulator, preventing horizontal shifts of a locking point and a false locking point, and reducing the occupied PCB area.
