CT: One of the best technologies to achieve real-time observations is the use of submarine cables, which have long histories of technological developent and proven field works in telecommunication. Although fiber-optic submarine cables apply very advanced and reliable technology, using new fiber-optic submarine cables is extremely costly. Another kind of submarine cable is the coaxial cable, which can provide electrical power and real-time telemetry similar to fiber-optic cables.

N: 1. submarine (adj.): 1640s, from sub- (word-forming element meaning “under, beneath; behind; from under; resulting from further division,” from Latin preposition sub “under, below, beneath, at the foot of,” also “close to, up to, towards;” of time, “within, during;” figuratively “subject to, in the power of;” also “a little, somewhat”) + marine (early 15c., “pertaining to the sea,” from Middle French marin, from Old French marin “of the sea, maritime,” from Latin marinus “of the sea,” from mare “sea, the sea, seawater,” from PIE mori- “body of water, lake”; the Old English word was sælic).

Technically, in nautical use, a rope 10 or more inches around, to hold the ship when at anchor; in non-nautical use, a rope of wire (not hemp or fiber). Given a new range of senses in 19c.: Meaning “message received by telegraphic cable” is from 1883 (short for cable message). Cable car is from 1879. Cable television first attested 1963; shortened form cable is from 1972.
2. A submarine cable is an electrical conductor or optical cable specially designed to convey messages while immersed in a body of water.
