“…If loss must be avoided, the minimum bending radius must not exceed ten times the outer diameter of the cable type. Similarly, temperature, tensile stress or severe force may also affect micro-bending [24]. It is irreversible.…”

Many of the optical fibre cables comprised of 1310 nm zero-dispersion single-mode (SM) optical fibres installed in underground/conduits and access networks. Currently, there have been several studies on active network systems, which are designed to increase transmission capacity and flexibility. The application of active communication devices like the wavelength division multiplexing (WDM) systems, usually using SM optical fibre for transmission in the 1310–1625 nm window wavelength, proves very effective in decreasing the installation costs and high signal attenuations. It was imperative to examine the wavelength dependency of such transmission characteristics of SM optical fibre cables previously installed and in which several optical fibres were spliced. Analysis for such network has been performed and monitored over 1550–1625 nm wavelength. Results show that the spectral characterization and analysis of a long-haul optical network system operating at the 50-GHz-spaced 80-dense wavelength division multiplexing (DWDM)-channel can be used to identify the presence of faults.

Optical cables are enormous transmission media that carry high‐speed data across transatlantic, intercontinental, international boundaries, and cities. The optical cable is essential in data communication. The cable has become an indispensable component in optical communications infrastructure; hence, conscious efforts are always adopted to prevent or minimize faults in the optical network infrastructure. Typically, tracing fault in the underground optical network has been difficult even though the optical time‐domain reflectometer (OTDR) has been used to measure the distance of faults in the underground fiber cable. The methodologies deployed in the reviewed literature indicate a vast gap between the fault distance measured by the OTDR and the actual distance of fault. This paper observed the difficulties involved in tracing the actual spot of fault in the underground optical networks. The difficulty of tracing these underground faults mostly result in an undue delay and loss of revenue. This research presents a machine learning approach to predict the actual location of a fiber cable fault in an underground optical transmission link. Linear regression in the python sci‐kit learn library was used to predict the actual location of a fault in an underground optical network. The mean square error and MAE evaluation matrix used provided good accuracy results of 0.061291 and 0.080143, respectively. The result obtained in this paper indicates that faults in underground optical networks can be found quickly to avoid the delays in the fault tracing process, which leads to an excessive revenue loss.

“…Optical communication systems have also been deployed in various private and public organizations to enhance the quality of services they provide (Velmuzhov et al, 2018). Research work on fault tracing in FOC network infrastructure (Urban et al, 2013) has predominately been done by the measurement of the fault distance of the underground FOC using backscattered light principles (Thongdaeng and Worasucheep, 2016). OTDR uses this principle to measure fault distance in fiber optics cables (El-Sayed et al, 2010;Kumar and Rajouria, 2012).…”
