Selecting cables is a crucial section of network design. Required data rate, cost and distance all dictate the product range of choices for each connection. Some connections require an obvious cable option. But others can decide from a selection of possible selections.

Network services, like file sharing, internet access, printing and email, are typical delivered to end users via the network infrastructure. That infrastructure usually includes switches, routers and -- underpinning all of it -- network cabling, among the oldest and most essential the different parts of network architecture.
A fast history of network cables

Digital communication is not quite a new idea. In 1844, Samuel Morse sent a note 37 miles -- from Washington, D.C., to Baltimore -- using his invention, the telegraph. This could seem such as a far cry from current computer networks, nevertheless the principles would be the same.

Morse code is a type of binary system that uses dots and dashes in different sequences to represent letters and numbers. Modern data networks use ones and zeros to attain the exact same result.

The difference between now and then is the speed where data is transmitted. Telegraph operators of the mid-19th century could transmit perhaps 4 or 5 dots and dashes per second. Computers can now communicate at speeds all the way to 100 Gbps -- or, put another way, 100,000,000,000 separate ones and zeros every second.

Even though the telegraph and teletypewriter were the forerunners of data communications, computers advanced with ever-increasing speeds. That advancement drove the development of faster networking equipment. In the act, higher-specification cables and connecting hardware were required.

1. Coaxial cable

Coaxial cable, or coax, is one option for network cabling. An inner conductive core is surrounded by way of a conductive, shielding layer. This shielding layer is then surrounded by an external protective layer.

The core that carries the signals is solid copper, copper-shielded steel cable or braided copper. Core and conductive shields operate in differential mode to avoid the emission of electromagnetic interference and the intrusion of external interference.

Coax features a long history. In the mid-19th century, it absolutely was used for undersea cabling. Today, it is utilized in a wide selection of applications, including residential broadband, telephone lines, and connections to radio and TV broadcasters.

Within data centers, coax is frequently employed for fiber channel connections between servers and disk drives. Its resistance to electrical noise helps it be valuable in noisy environments, such as for example industrial facilities.
