Abstract
This application provides a clock frequency determining method and a clock frequency determining apparatus. The method includes: An access network device receives a combined optical signal from a radio over fiber RoF device, where the combined optical signal is obtained by coupling an optical signal of a first frequency and an optical signal of a second frequency; the access network device converts the combined optical signal into an electrical signal; and the access network device sets a local clock frequency based on a signal frequency of the electrical signal and a first preset rule, where the signal frequency of the electrical signal is equal to an absolute value of a frequency difference between the first frequency and the second frequency.
