摘　　要：光纤通信网络传输信道畸变,影响了光纤通信网络传输质量,为此,提出了基于载波调制的光纤通信网络传输质量提升方法。构建光纤通信网络传输的传输大数据采集和特征分析模型,结合模糊聚类方法进行光纤通信网络输出信道的扩频处理,采用载波调制方法进行光纤通信网络的波特均衡控制,抑制光纤通信网络传输信道畸变,优化光纤通信网络传输质量。结果表明,采用该方法进行光纤通信网络传输精度可达96.2%,网络信道均衡性较好,输出误码率较低,在16 dB和13 dB时可达最低误码率,有效提升了光纤通信网络传输质量。The transmission channel distortion of optical fiber communication network affects the transmission quality of optical fiber communication network.Therefore,a method to improve the transmission quality of optical fiber communication network based on carrier modulation is proposed.The transmission big data acquisition and characteristic analysis model of optical fiber communication network transmission is constructed.Combined with the fuzzy clustering method,the spread spectrum processing of the output channel of optical fiber communication network is carried out.The carrier modulation method is used for baud equalization control of optical fiber communication network,so as to suppress the transmission channel distortion of optical fiber communication network and optimize the transmission quality of optical fiber communication network.The results show that the transmission accuracy of optical fiber communication network using this method can reach 96.2%,the network channel balance is good,the output bit error rate is low,and the lowest bit error rate can be reached at 16 dB and 13 dB,which effectively improves the transmission quality of optical fiber communication network.
