Provided are a crosstalk suppression method and device. The method comprises: by means of acquiring a first electrical signal for indicating a data bit stream which is represented by a first optical signal output by a laser diode in a light transmitting-receiving integrated module, and transmission parameters of a photodiode, adjusting the first electrical signal according to the transmission parameters of the photodiode, acquiring a third electrical signal for indicating an electrical signal output by converting the first optical signal which is output by the laser diode via the photodiode, and carrying out subtraction processing on a second electrical signal and the third electrical signal which are output by the photodiode in the light transmitting-receiving integrated module, so that in the electrical signals output by a PD, electrical signals which are generated by an optical signal output by an LD, and reflected or refracted to enter the PD can be removed, thereby suppressing crosstalk, and improving the sensitivity of a light transmitting-receiving integrated module. |
