Abstract: A parameter adjustment method and apparatus are provided. The parameter adjustment method for a communication device with a SerDes link includes: acquiring, by the communication device, a current ambient temperature of the communication device; and if according to a preset correspondence between a temperature range and a parameter, the current ambient temperature is determined to be not corresponding to a SerDes parameter of the communication device, adjusting the SerDes parameter of the communication device according to the correspondence. The SerDes parameter of the communication device is adjusted in real time, thereby improving reliability of a SerDes link of the communication device, and reducing a bit error rate of the SerDes link.
