Ethernet Cabling also known as Enterprise Fiber Optic Cabling:

An optical fiber or optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer excessively. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.

Optical fibers typically include a core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by the phenomenon of total internal reflection which causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers, while those that support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters.

Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters.

The per-channel light signals propagating in the fiber have been modulated at rates as high as 111 gigabits per second (Gbit/s) by NTT, although 10 or 40 Gbit/s is typical in deployed systems.

ANSI/TIA-568.3-D, Optical Fiber Cabling And Components Standard, Ed. D, 10-2016. An IEC standard ISO/IEC 11801 provides similar standards.

EIA/TIA 568 Standard: 

ANSI/TIA-568 is a set of telecommunications standards from the Telecommunications Industry Association (TIA). The standards address commercial building cabling for telecommunications products and services. As of 2017, the standard is at revision D, replacing the 2009 revision C, 2001 revision B, the 1995 revision A, and the initial issue of 1991, which are now obsolete.

Perhaps the best known features of ANSI/TIA-568 are the pin/pair assignments for eight-conductor 100-ohm balanced twisted pair cabling. These assignments are named T568A and T568B.

An IEC standard ISO/IEC 11801 provides similar standards for network cables. 

The data cabling and wiring system is fiber optic cabling. Some of the components of the cabling system include: fiber patch panels, mid-couplers, unjacketed pigtails and patch cords fiber data wiring solution features a thin glass core that transmits laser light pulses. Fiber optic data cabling allows communication signals to be transmitted much faster, at a higher bandwidth and over much greater distances than copper data cabling systems. Because light is transmitted at a much higher frequency. Fiber optic data cabling offers greater signal capacity. Fiber optic cabling is smaller than copper cabling and is also impervious to interference, with a much lower transmission loss.
