This document presents a troubleshooting guide for fiber optic cables once deployed and in regular use. If a fault causes service interruption, it will be handled according to the fault repair procedure, and if it does not affect the business but does not cause a fault, it will be handled according to the cutover procedure. The interruption of the optical cable line caused by external factors or the optical fiber itself, which affects the communication service, is called the optical cable line fault. Although flexible, fiber optics are made of glass and this property makes it very fragile. The differences for the two types of fiber are due to the drive characteristics of the transmitters into the different diameters of POF and HCS cables.
