摘　　要：提出采用单模光纤作为XCTD的传输信道,首先对使用漆包线作为传输信道所面临的难题进行了简要的分析;其次,分析了单模光纤技术优势;最后,针对XCTD工作环境中海水温度变化对光纤传输信道带来的影响进行了理论研究和实验验证,实验结果表明,单模光纤信道在海水介质及0~20℃海温变化下,以10 MB/S的传输速率传输数据时误码率为0,且损耗变化几乎可以忽略,大大提高了信号传输的速率和传输稳定性,实验结果说明采用单模光纤作为XCTD的传输信道具有一定的可行性。This paper puts forward with using the single-mode optical fiber as the transmission channel of XCTD. Firstly,this paper makes a brief analysis on the problems in using enameled wire as the transmission channel. Secondly, it analyzes the advantages of single mode optical fiber technology. Finally, it makes the theoretical research and experimental verification for the influence of seawater temperature change on the optical fiber transmission channel. The experimental results show that the error rate in the transmission rate of 10 MB/S is 0 and the loss can be negligible when the single-mode optical fiber channel is used in the sea water with temperature changes from 0 to 20 ℃. It greatly increases the rate of signal transmission and the transmission stability, and shows that using the single-mode fiber as the transmission channel of XCTD has certain feasibility.
