    This is an accepted version of this page This is the latest accepted revision, reviewed on 22 December 2024. 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 ...

  3. Terrestrial cable - Wikipedia

    en.wikipedia.org/wiki/Terrestrial_cable

    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. [4]

  4. Direct-buried cable - Wikipedia

    en.wikipedia.org/wiki/Direct-buried_cable

    Most cable of this kind is coaxial or bundled fiber-optic cable. In the 20th century much of it was filled cable. Direct-buried cable is cheaper and easier to lay than other kinds of cable that require protection from the earth. [1] However, DBC is also easily cut during digging or other excavations.

  5. Utility tunnel - Wikipedia

    en.wikipedia.org/wiki/Utility_tunnel

    Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried. One may also be referred to as a services tunnel, services trench, services vault, or cable vault. Smaller cable containment is often referred to as a cable duct or underground conduit.

  6. Optical ground wire - Wikipedia

    en.wikipedia.org/wiki/Optical_ground_wire

    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 .

  7. Optical fiber - Wikipedia

    en.wikipedia.org/wiki/Optical_fiber

    A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one end. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other.

    In the latter case, the cables might be direct buried or installed in ducts. The first is more common for copper balanced cables; the latter for fibre optic cables. The ducts in which the fibre optic cables are installed are usually made of polyethylene. They have a size ranging from typically 25 mm to 100 mm.

  9. Structured cabling - Wikipedia

    en.wikipedia.org/wiki/Structured_cabling

    Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using various kinds of cable, most commonly Category 5e (Cat 5e), Category 6 (Cat 6), and fiber-optic cabling and modular connectors.
