英文摘要：

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.
