Abstract：With the more and more extensive application of optical cable communication in the field of communication, effective optical cable monitoring technology is becoming more and more important, when the optical cable is interrupted due to loss, how to quickly and accurately determine the interruption fault point, timely reduce or avoid the loss caused by the interruption of the optical cable, is the purpose of optical cable safety monitoring technology. This paper innovatively uses the technology combined with OTDR and OSW to monitor the safety of 16 optical fiber communication lines at the same time, and builds a set of intelligent monitoring optical cable on-off programs based on Java, MySQL, HTML and other languages and frameworks, and finally evaluates the danger level of the lines through SVM algorithm, realizes real-time monitoring and fault location of 16 communication lines, and verifies its accuracy through field tests in Jiujiang City, Jiangxi Province, which has application value and reference significance.
