Cable assembly containing one or more optical fibers that are used to carry light A TOSLINK optical fiber cable with a clear jacket. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly ...
A terrestrial cable is a communications cable which crosses land, rather than water. Terrestrial cable may be subterranean (buried) or aerial (suspended from poles ), and may be fiber or copper . [ 1 ] [ 2 ] The term "terrestrial cable" is principally used to distinguish it from submarine cable , [ 3 ] although some overlap exists between the two.

Power cables and fiber-optic cables that deliver television and broadband services are buried underground.
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications .
