Data cable connections form the backbone of any reliable network for an office or a large business setup. The right choice of data cables and knowledge of their properties can greatly affect your network’s performance. This guide covers the different types of data cables, their uses, and best practices to ensure optimal connectivity.
Knowing the Types of Data Cables
There are several data cables, each used for specific applications and performance. Here are some of the most common types:
Twisted Pair Cables: Twisted pair cables are the most common cables in Ethernet networks. The cable contains pairs of wires that are actually twisted to reduce electromagnetic interference, also abbreviated as EMI. These cables can be subcategorised into two main categories:
- Unshielded Twisted Pair (UTP): This includes no extra shielding but is more flexible and economical.
- Shielded Twisted Pair (STP): This has an extra shield, usually a foil or braid, to reduce interference further. Best used in areas with high EMI.
Optic Cables
Optical fibre cables are very different. They use light instead of electrical signals and allow unbelievably high speeds without interference. Common uses are long-distance communication or extremely high-speed connections.
Ethernet Cables: The standard forms of Ethernet cables include Cat5e, Cat6, and Cat6a. They are usually twisted pairs and form a significant component of a LAN (local area network). The length is also important, because standard Ethernet cables should not exceed 100 meters to avoid signal degradation.
Crossover Cable vs. Straight Through Cable
Straight-Through Cable: This kind of cable connects different devices, such as a computer to a router.
Crossover Cable: Designed to connect the same devices, such as two computers or switches.
Choosing the correct one gives ideal communication between the devices.
Shielding: Foil or Braid?
Shielded cables are available with foil or braid shielding to minimise interference:
- Foil Shielding: This provides complete coverage and is best at stopping EMI.
- Braided Shielding: Has greater flexibility and strength but does not block interference as much as foil.
In some applications, both (foil and braid) are combined for maximum protection.
Key Considerations in Selecting Data Cables
Cable Length
The longer the cable, the higher the risk of signal degradation. Copper Ethernet cables should not exceed 100 meters in length.
Environment
Industrial or high-interference environments such as warehouses, call for foil or braid shielded cables.
Cable Tester Usage
A cable tester is the best tool for ensuring that your data cable connections are working properly. It checks continuity and wiring configuration and even detects faults such as breaks or crossed wires.
Best Practices for Network Setup
Labelling: Label cables clearly to avoid confusion during maintenance.
Avoid Overbending: Data cables should not be bent beyond their recommended radius to avoid performance issues.
Proper Shielding: In areas with interference from electrical equipment, shielded cables should be used.
Testing: Test your network cables regularly with a cable tester to detect issues.
