The handbook gives guidelines related to ‘Fault analysis and repair’ as well as ‘maintenance and inspection’ of fibre optic links. The first deals with what to do when something goes wrong – how to go from a fault notification to locating the fault, and finally, repairing it. The second covers the recommended procedures for upkeep and maintaining harness health over the lifetime of its installation.
