A method, apparatus, device and medium for processing optical fiber time delay

Abstract

This invention discloses a method, apparatus, device, and medium for processing optical fiber delay. The method includes: acquiring a first high-precision time signal and a second high-precision time signal of the transmission link during optical signal transmission; when a transmission delay exists between the first and second high-precision time signals, acquiring high-precision time signals corresponding to a master station device and at least one slave station device, respectively, as a third high-precision time signal; performing self-calibration verification on the master station device and slave devices based on the third high-precision time signal; automatically locking the transmission link when the self-calibration verification of the master station device and slave devices is completed; and adjusting the time frequency corresponding to the third high-precision time signal to ensure that the time frequencies of the master station device and at least one slave device are the same. This technical solution can eliminate the problem of decreased transmission delay accuracy caused by dispersion of optical signals of different wavelengths, ensuring that the time frequency accuracy is the same at each time synchronization point.
