Abstract: In order to solve the problem of low signal transmission efficiency and susceptibility to noise interference in online monitoring systems in fibre optic communication construction, this paper conducts effective research on the analysis and design of changes in fibre optic cable online monitoring systems using digital CT. This paper conducted tests from three aspects: real-time analysis of changes, accuracy, and signal transmission efficiency. The test results show that at the accuracy level of change analysis, the average relative error level of digital CT used for fibre optic cable change analysis is about 6.381%, while the average relative error result of fibre optic change analysis in traditional online monitoring systems is about 7.595%. From the comparison of accuracy results, digital CT can enhance the stability and reliability of online monitoring systems, improve the accuracy of fibre optic change analysis, and promote the healthy development of fibre optic communication.

Keywords: optical fibre; digital communications technology; online monitoring system; change analysis and design.
