After the analysis of the test results in Table 3, it canbe concluded that under different communication signallengths, with the gradual increase of optical signal-to-noise ratio, the communication bit error rate results of thesignal are all below 0.001. When the communicationsignal length is 1100, the maximum bit error rate resultsare 0.0095, and the minimum bit error rate results are0.0006. Therefore, the proposed method can reliablycomplete the laser interface interference signal filtering ofoptical fiber communication network, and reduce thenoise in the signal, and effectively separate theinterference signal to ensure the communication effect ofthe network.
