How do undersea fiber-optic cables work?

How do cables work? 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.

How well are cables protected in the deep sea?

This provides some level of protection. In the deep sea, the ocean’s inaccessibility largely safeguards cables – they need only to be covered with a thin polyethelene sheath. It’s not that it’s much more difficult to sever cables in the deep ocean, it’s just that the primary forms of interference are less likely to happen.
