Localization and testing for submarine cable fault

It is very important to maintain the normal operation of subnmarine cable systems since the requirement for the Intemet is increased drastically. When the submarine cable fault occurs, it is a key step to localize the fault position exactly and rapidly. Some fault testing methods are introduced according to various submarine cable faults so that the faults can be detected and localized in a timely manner to ensure the restoration of cable systems as soon as possible.
