Data Cable Types

09.12.24 ● 3 minutes

Data cables are used to transmit electronic data from one location to another. Data cabling is either copper or fibre optics, and it is widely utilised in computer and communications systems.

They can be classified into three major types:

Coaxial cables (copper)
Twisted pair cables (copper)
Optic cables (fibre)

Each has distinct properties that makes them identifiable.

Coaxial

Coaxial cable carries high frequency signals, and it is mostly used in older computer networks. These types of cable have a solid wire core conductor that is enclosed in an insulator and covered by a metal foil outer conductor. The circuit is completed by this outer conductor, and the entire cable is secured by a plastic cover.

Though coaxial cables have a larger bandwidth, they have a far higher attenuation than twisted-pair cables. It's common in digital telephone cable wiring networks, where a single cable may transmit up to 600 Mbps of data.

Coax cabling requires the use of a specific connection known as a BNC connector, which is used to connect the cable's end to a device.

Twisted Pair

Twisted pair cables are primarily used for telecommunications and computer networks. They are made up of two copper cores that are twisted together, and each have their own plastic insulation – one carries the signal while the other is used as ground reference.

The benefit of twisting is that external factors affect both wires equally. The twisting of the wires protects data transfers from signal deterioration. However, the typical length of a twisted pair cable before signal loss is around 300 feet.

Types of Twisted Pair Cables

UTP (Unshielded Twisted Pair)
STP (Shielded Twisted Pair) cable – has one additional metal shield covering the insulated twisted pair conductors

Fibre Optic Cable

Fibre optic cables provide fast connections to the Internet via data signals in the form of light. They are primarily used in cable and telephony companies.

The light channel consists of two major parts:

Core
Cladding – protective cover of the core

Fibre optic cable is lightweight, and unlike the other two data connections, it does not suffer from signal deterioration. Fibre optic cable, on the other hand, is more costly and more delicate due to the glass sections of the cable.

Types of Connectors

SC connector – used for cable TV
ST connector – used for connecting cable to networking devices

Different Types of Connector for Data Cables

Registered Jack 45 (RJ45) – found in UTP & STP cables
Straight Tip (ST) – usually found on the end of a multi-mode cable
Subscriber Connector (SC) – found on Multimode and Single Mode optical fibre cables
Lucent Connector (LC) – found on high-density deployments where multiple fibres would be terminated in a confined space
Multi-fibre Push On (MPO) – duplex connector that was created with the intention of being able to be connected several times without causing any possible connection troubles

What is the Most Used Cable Type for Networking?

Unshielded Twisted Cable is the most popular and, in most cases, the best solution for LANs. In some situations, however, the Shielded Twisted Pair may be preferable.

Connecting Data Cables

Ethernet connections provide a better and more secure connection than wireless ones. The cables are also affordable, simple to locate, and utilise - one end is connected to your router, while the other is connected to the device.When you need extra length than a single cable can allow, instead of buying a longer cable, you may consider connecting two shorter ethernet cables.How to Connect Two Ethernet CablesTo connect two data cables (Ethernet) you can use a traditional RJ45 coupler. It is inexpensive and simple to use. The coupler has two ethernet ports, one on each end, in order to form one longer cable by bridging the gap between them.However, if more than one coupler is used, the signal may be degraded, or the strength of the connection could be affected. The alternative option is to re-size the cable by cutting it to the needed/required length, for which you will still need a coupler as well as wire cutters and a crimping tool.How to Cut an Ethernet Cable at the Ideal LengthStarting with a single lengthy cord is a simple and affordable approach to connecting ethernet cables. You may buy inexpensive cables in a variety of lengths; simply select the one that is long enough for your installation/arrangement.Another thing to consider is there are several types of data cable such as Cat 5e and Cat 6 cable – they function the same way but have different data transmission rates.Follow the guide below, to cut the cable in six simple steps:Step 1: Measure the length of the cable – do not cut the exact same length that you need, always leave a bit more and then clip it using the wire cutters Step 2: Strip off the protective outer jacket – using the crimping tool remove a few inches of it carefully not to damage the thin wires Step 3: Divide the wires – separate the four pairs of wires, when finished you should be left with eight individual ones instead Step 4: Put the wires in the correct order – there is an exact order in which the wires should be put- the most common method used is the T-568B: Orange/White > Orange > Green/White > Blue > Blue/White > Green > Brown/White > Brown.Step 5: Organise the wires - ensure that they are in the same order on both sides of the cable then press them together. When they are straight and there is no gap between them, cut off the excess, leaving approximately half an inch behind. Make sure you cut them straight down the middle and not at an angle. Step 6: Put the connector on - with the clip part of the connection facing away from you, carefully slip it over the wires. Each wire will be able to fit into a slot. When all the wires are at the connector's edge, push down on the RJ45 coupler using your crimping tool. How Many Data Cables Can RJ45 Couplers Connect?There is no limit on how many cables can be connected to RJ45 couplers. Nonetheless, the data transmission should be prioritised. Ethernet cables transmit connection to each other and having multiple couplers or/and cables will decrease both the quality and the speed of the connection.ConclusionCutting the length of a cable is probably the most reliable option for long-term use, but using connectors can be an easy, quick, and inexpensive fix.For more information on our range of data and ethernet cables, get in touch with our expert team!
