Some Questions with Us


Below are few of the generally asked questions you may be interested in.

As of early 2017, there are approximately 428 submarine cables in service around the world.

The total number of cables is constantly changing as new cables enter service and older cable are decommissioned.

Modern submarine cables use fiber-optic technology. Lasers on one end fire at extremely rapid rates down thin glass fibers to receptors at the other end of the cable. These glass fibers are wrapped in layers of plastic (and sometimes steel wire) for protection.

For most of its journey across the ocean, a cable is typically as wide as a garden hose. The filaments that carry light signals are extremely thin — roughly the diameter of a human hair.

These fibers are sheathed in a few layers of insulation and protection. Cables laid nearer to shore use extra layers of armoring for enhanced protection.

Yes, cables go all the way down. Nearer to the shore cables are buried under the seabed for protection, which explains why you don’t see cables when you go the beach, but in the deep sea they are laid directly on the the ocean floor.

Of course, considerable care is taken to ensure cables follow the safest path to avoid fault zones, fishing zones, anchoring areas, and other dangers. To reduce inadvertent damage, the undersea cable industry also spends a lot of time educating other marine industries on the location of cables.
