Abstract： This article explores the faults and protection technologies of railway communication optical cables. Firstly，the common types and causes offaults inrailway communication optical cables were analyzed indetail，and the basic principles offault detection and localization technology Were explained through specific cases.Then，by introducing data such as fiberoptic cable atenuation characteristics and fault location errors，acomprehensive fault protection technology system was constructed，covering physical protection measures，optimization of monitoring systems，and applicationof intellgent warning technology.Intendedto provide theoretical basis and technical support for improving the stability ofrailway communication optical cable operation and reducing the occurrence of faults.

Keywords： railway communication; fiber optic cable malfunction; fault detection; protective technology; intelligent monitoring
