Definition of network cabling
Network cabling refers to the physical framework connecting computers and devices to a network. Installation can be handled by either the internal IT department or an external contractor, but regardless of the installer, correct installation is paramount.
Inadequate network design can lead to data loss or system downtime. To mitigate these risks, it’s essential to comprehend the significance of correctly installed network cabling.
Why is network cabling important?
Network cabling serves as the backbone of your network, facilitating communication among network hardware and carrying data from one device to another. Essentially, it enables connectivity for sharing information or resources like printers or internet access.
Network cabling is an indispensable component of any network, enabling communication among connected computers and devices. Without network cables, transmitting data between devices would be impossible. Hence, understanding the necessary cable types for your network and investing in high-quality cabling during network establishment or upgrades are vital considerations.
Types of network cabling
To understand network cabling and its importance, you should know the different types of network cables that are available. The following are the four main types of network cables.
Coaxial Cable. This type of cable is commonly used in older buildings. It uses a copper core surrounded by an insulating material, then a metal sheath. The metal sheath gives it strength while keeping out outside elements such as water or dirt. It is straightforward to install and is often used in home networks. This type of cable is not recommended for use in commercial buildings because it can only transmit signals over short distances.
Fibre Optic Cable. This type of cable was developed as a replacement for coaxial because it can carry more data over longer distances with less loss than coaxial cables. Fibre optic cables consist of two thin pieces (sometimes called fibres) made from plastic or glass that transmit information through pulses of light instead of electricity like other types of cables do. They have several advantages, including faster transfer rates, greater bandwidth capacity, immunity from electromagnetic interference, longer distances between nodes (100 meters compared to 10 meters on UTP), resistance against corrosion and fire damage if sealed adequately at each endpoint within a conduit leading outside building walls which may contain one or more fibre optic pair(s).
Shielded Twisted Pair (STP) Cable. Shielded twisted pair (STP) cable is a single-pair wire consisting of four pairs: two pairs for transmitting signals and two for receiving them. This type of cable is commonly used in telephone systems and computer networks because it can withstand interference from power lines, radio waves, and other sources that could otherwise disrupt regular operation by introducing noise into signals being transmitted over long distances via copper wire connections between servers or desktop computers located within buildings
Unshielded Twisted Pair (UTP) Cable. Unshielded twisted pair (UTP) is most commonly used in telephone lines because it is cheaper and easier to install than other cabling systems, such as fibre optic cable or coaxial cable. UTP is also used in computer networks because it can be run through walls and ceilings without needing additional tools or special equipment. This cabling system relies on copper wires that are twisted around each other to reduce interference from external sources that could disrupt data transmission over long distances via copper wire connections between servers.
Benefits of network cabling
Network cabling forms the backbone of your business operations, enabling seamless connectivity among computers and devices for efficient file and information sharing.
However, beyond mere connectivity, cable networking offers several advantages. Here are some key highlights:
Enhanced network performance: Network cabling enhances network performance by delivering greater bandwidth and improved signal quality, enabling faster data transmission. Improved signal quality facilitates quicker media streaming, faster file downloads, and seamless video conferencing without static or interference.
Enhanced security: Network security is often overlooked in cabling setups, yet it’s crucial for both home and office networks. Proper cabling installation helps safeguard computer networks from external threats like viruses or hackers, preventing unauthorised access through vulnerable points such as USB ports or wireless routers.
Cost savings: Proper cabling systems reduce costs by eliminating the need for expensive equipment like repeaters. This is particularly beneficial for companies with weak signal infrastructure, avoiding the expense of additional hardware due to inadequate bandwidth, which results from inadequate planning during initial construction/installation stages.
Improved productivity: A robust, high-speed network enables employees to complete tasks more efficiently, leading to a more productive workforce and enhanced overall business productivity. Streamlined workflows allow employees to allocate more time to focus on new projects or other critical areas, as they spend less time on daily tasks.
