Cable Faults JOLT - external aggression, anchor or skid from commercial fishing net but not actually breaking cable. Sometimes the bend is so sharp fibers will attenuate but not break, other times cable will part elsewhere along the cable. Planned restoration and repair required. Shunt Fault – external aggression, friction damage has caused damage to the cable but not actually breaking the cable. The damage extends to the core power cable causing a leakage to ground; though not always traffic affecting indicative of a larger problem. Planned Restoration and Repair required. Cable Break – immediate restoration and repair required Executed by Cable Administrator and RCO/RLO. 29 CORPORATE Confidential & Proprietary
