How tough is the cable?

The cables are very robust and used throughout the world. They are engineered to withstand this environment and are laid with methods and locations to minimize wear and avoid being dragged. Considering the trans atlantic cable (communications) was laid in the mid 1850’s and the use of electrical submarine cables for power began in the 1950’s there is a lot of history and experience.
