随着光缆线路的大量敷设和投入使用,光缆通信系统的可靠性和安全性越来越受到人们的关注。电力架空光缆在我国的应用已初具规模并不断发展,做好电力架空光缆的维护工作,使之发挥更大的社会经济效益,是摆在电力通信工作者面前的重大课题。据统计资料显示,光纤通信系统中使通信中断的主要原因是光缆线路故障,约占统计障碍的2/3以上。因此从某种意义上讲,光纤通信系统的安全性取决于光缆线路的安全性。
With the laying and putting into use of a large number of optical cable lines, the reliability and security of the optical cable communication system have drawn more and more attention. The application of overhead optical cable in our country has begun to take shape and continues to develop. To do a good job of maintaining aerial overhead optical cable and make it have greater social and economic benefits is a major issue facing electric power communication workers. According to statistics, the main reason for communication interruption in optical fiber communication systems is the failure of optical cable lines, accounting for more than 2/3 of the statistical obstacles. Therefore, in a sense, the security of optical fiber communication system depends on the security of the optical cable.
