  • What are the four types of optical cable line faults

    What are the four types of optical cable line faults

    The causes of cable line failure can be roughly divided into four categories: external force factors, natural disasters, defects of the cable itself and human factors. Line failure caused by external force factorsClassification of cable line faults According to the interruption of the optical fiber of the faulty cable, the fault types can be divided into three types: total interruption of the optical cable, interruption of part of the bundle tube, and interruption of part of the fiber in a single bundle. The interruption of optical cable lines due to external factors or the optical fiber itself, which affects communication services, is called optical cable line failure. Service interruption is not always caused by cable interruption. Knowing how to recognize and diagnose. In this article, we will explore the most common faults in fiber optic cables, their causes, and effective repair methods.
