A shunt fault is a type of fault that occurs in submarine communications cables. Many such cables use underwater repeaters or amplifiers to boost signals being passed along the cable. These repeaters or amplifiers are powered from either end of the cable using Power Feed Equipment. This is achieved by applying a voltage to the metallic (usually copper or aluminium) core of the cable that surrounds the optical fiber.
