The invention provides a method for eliminating error between different high-speed serial links through FIFO (First Input First Output). The method comprises the following steps of: S1, receiving synchronous data on each link and storing the synchronous data in FIFO which is correspondingly arranged in each link; S2, setting a Pop time point and simultaneously extracting the synchronous data from the corresponding FIFO on each link at the Pop time point; and S3, recovering the synchronous data which is extracted from the corresponding FIFO from each link into an original data frame. Compared with the prior art, the synchronous data transmitted on each link is stored in each FIFO which is correspondingly arranged, and data in each FIFO is simultaneously extracted out when the FIFO is read, so that Skew between every two links is eliminated, and furthermore, the data which is transmitted by the high-speed serial link is more easily recovered.
