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.

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 ...
Outside plant cabling, whether copper or fiber, is generally installed as aerial cable between poles, in an underground conduit system, or by direct burial. [2] Hardware associated with the outside plant must be either protected from the elements (for example, distribution frames are generally protected by a street side cabinet) or constructed ...
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]
A cable reel trailer with conduit that can carry optical fiber Multi-mode optical fiber in an underground service pit. An optical fiber cable consists of a core, cladding, and a buffer (a protective outer coating), in which the cladding guides the light along the core by using the method of total internal reflection.
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 .

Gap loss can be caused by many factors, but the most common is poorly fitted multi-sectional fiber optic cables. If there is a break in a directly buried fiber optic line then usually there will simply be a loss of signal.
