Location of direct-buried optical cable for lightning protection
Newly built silicon core pipes or direct buried fiber optic cables with metal components should be set up according to the soil resistivity (ρ10) at a depth of 10m to provide a lightning protection line (also known as "discharge line"). But lightning has been known to overcome the cable insulation of a few millimetres AND the soil cover combined. It is intended for personnel with prior experience in the planning, engineering, or placement of buried fiber optic cable. ble may extend of the reel and beco ssible safety hazard and/or damaging the cable. 101 describes characteristics, construction and test methods of optical fibre cables for buried application.
