Which Type Of Network Cable Is Commonly Used To Connect Office Computers To A Network?

Which Type Of Network Cable Is Commonly Used To Connect Office Computers To The Local Network? Many businesses don’t give network cables a second thought. However, the right type of cable can significantly improve speed and reliability. There are several different types of network cables, including twisted pair, coaxial, and fiber optic.

Unshielded twisted pair (UTP) uses copper wire pairs twisted together to reduce electronic interference. Foiled twisted pair (FTP) has foil shielding that further reduces electromagnetic interference. Both can transmit 10 Mbps over short distances.

Coaxial Cable:

Coaxial cable, also known as hard-line, features a round copper conductor that is shielded. By layers of aluminum and other metals. This superior shielding supports much longer cable lengths and protects the signals against electromechanical interference (EMI). Coaxial cables are more expensive than twisted pair cables but they can carry up to 80 times as much data. Their higher transmission speeds make them suitable for long-distance networks.

Coax is used to connect cable television and home video equipment, as well as amateur radio equipment. It was a popular choice for networking until the development of cheaper and more reliable twisted pair cables. It is still used to connect satellite dishes and radio antennae to their respective receivers. As well as in some high-speed applications such as cable broadband internet connections.

The electrical signal in a coaxial cable is carried by an inner conductor that is surrounded by concentric conducting shields. The insulating layer between the two layers may contain foam plastic, air, or other gases to reduce loss. The outer conductive shields are made of metallic wires. They are woven together and wrapped in an insulated sheath or jacket.

It is important to use high-quality coaxial cables for network installations and ensure that the connectors are secure, as they can easily be damaged by physical damage or improper handling. It is also important to keep cables away from fluorescent light boxes and other sources of electromagnetic interference.

Twisted Pair Cable:

Twisted pair cabling is what is used to connect most modern office computers to a network. It consists of pairs of copper wires that are color-coded and twisted together. The twisting reduces electrical interference that can cause signal degradation or even total loss of data transmission. It also increases the signal-to-noise ratio, which allows for higher data transmission rates than would be possible with untwisted wires.

Which Type Of Network Cable Is Commonly Used To Connect Office Computers To The Local Network:

Different types of twisted-pair cabling are designated by various standards developed by the Electronics Industry Alliance and Telecommunications Industry Association (EIA/TIA). The most common twisted pair cable is known as unshielded twisted pair (UTP) network cable, which doesn’t have metallic shielding around each copper wire. Other twisted pair cables may have foil shielding or tinned copper braiding, and they can be categorized as either F/UTP or SF/UTP depending on the type of outer coating.

Both UTP and F/UTP cables have a core wire made of solid conductive copper and insulation. The insulation is usually made of a dielectric polymeric compound and protects the core from mechanical damage, abrasion, and corrosion. The twisted wires inside the cable have different twist rates to minimize the impact of one wire on another. The different twist rates also allow for a more balanced distribution of signals.


Unshielded twisted-pair cables have the potential to pick up electromagnetic interference from other electric or magnetic sources in their vicinity. This can be a problem for long-distance transmission over networks or for telecommunications applications. They can also suffer from reduced bandwidth compared to fiber optic cable. However, these cables are generally affordable and easy to install in a variety of settings.

Fiber Optic Cable:

Fiber optic cables are a more expensive network cable than copper alternatives, but they provide several benefits that make them worth the investment. For example, they are able to transfer data at a much faster rate than any other network cabling. They also offer greater bandwidth, which means more devices can be connected at once. Additionally, fiber-optic connections are less affected by electrical surges or outages than copper cables.

Fiber-optic cables consist of many thin strands of coated glass fibers, each measuring about eight microns in diameter — or about half the thickness of a human hair. Digitized information is coded into light pulses that travel along the glass fibers at the speed of light – about 186,000 miles per second. When the light reaches its destination, it is decoded into an electronic signal that can be understood by computers and other devices.

There are two main types of fiber optic cable: single mode and multimode. Single-mode fiber has a smaller core diameter than multimode, which reduces internal reflection and allows signals to travel over longer distances with less loss. Multimode fiber, on the other hand, has a larger core diameter, which allows multiple modes of transmission.

Both types of fiber optic cable require a media converter, which changes the light pulses into electrical signals that can be used by network equipment. When installing fiber-optic cables, it is important to leave plenty of slack and to test all cables as they are installed. When possible, route your cables away from fluorescent lights and motors, which can cause interference.

Patch Cable:

Ethernet patch cables, or simply patch cords, connect devices to ethernet switches, hubs, routers, and other network equipment. They are usually shorter than bulk copper Ethernet cables, and they have connectors on both ends. Generally, patch cords are not used over long distances. A specialized type of patch cord is a crossover cable. Which reverses the direction of transmission on one end, allowing two different kinds of devices to communicate with each other.

A twisted pair Ethernet patch cable typically looks similar to a telephone cable and is covered in a plastic sheath. But it has one key difference: each of its 8 conductors is made up of multiple fine strands. This allows a twisted pair patch cable to be more flexible than a solid-conductor Ethernet cable. Which has a rigid sheath and breaks easily when bent repeatedly.

Ethernet patch cables are also available in a range of categories, such as CAT 5, CAT 5e, and CAT 6, with each higher category offering successively faster data transfer speeds. A CAT5e patch cable can support up to 2.5 Gigabit of data per second, while a CAT6 patch cable can support up to 10 Gigabits of data per second. When choosing a cable, consider the amount of data you need to transfer and the length of your network. Generally, shorter patch cords are more convenient than longer Ethernet cables, which can be difficult to manage and can potentially interfere with other network devices.
