Structured Data Cabling FAQs

  • Structured cabling takes an organised approach to networks, using a central patch system that connects the different components of the system. Because it covers diverse functions like voice, data, and security management, components can include a wide range of devices such as phones, printers, and sockets, as well as routers and switches.

    Structured cabling follows a certain set of standards that specify details such as the layout and type of cables to use, and it’s convenient because components can be removed from or added to the network without too much adjustment.

  • Voice cabling is a basic part of every business and nearly every home. This refers to the network of cables and devices that handle basic voice communications such as your phone lines or telephone modem.

    Voice-grade cables are made of copper or fibre, and these are combined with telephone jacks so your telephone can be part of the local communication system.

    Capable of transmitting heavy data at real-time speed, voice cabling is commonly used with data cabling for more advanced functions like VoIP telephone and video calls.

  • Copper network cables come in different categories, from Category 3 to Category 8. The higher the category, the more recently it was invented and the higher its performance. The most common categories today are:

    • Category 5 – can handle a maximum of either 10 or 100 mbps, and its main application is for Ethernet data along with video and telephone
    • Category 5e – the most popular today because it’s low-cost with a maximum speed of 1 Gbps
    • Category 6 – has improved performance over 5e with a speed of up to 10 Gpbs, but it’s more expensive
    • Category 7 – comes with the same maximum speed as 6 at 10 Gbps but has higher bandwidth and less signal noise
  • Data cable standards define the guidelines and best practices for data networks, from testing requirements to which types of cable to use. These are established by different governing bodies such as the ISO/IEC, TIA, and CENELEC.

    When it comes to cables, you generally have to choose between copper or fibre optic. Copper is the more traditional and cheaper option, while fibre optic offers higher speeds at longer distances but at a higher cost. Each has its own standards, with several categories of copper cable available and fibre optic cables divided into single and multi-mode types.

  • Both Cat 5 and Cat 6 cables consist of twisted-pair cables made of copper, and they run at a maximum distance of 328 feet or 100 m. Cat 5 and Cat 5e alike can go up to 100 MHz bandwidth, but Cat 5 has a maximum speed of 10 or 100 mbps while Cat 5e can reach 1 Gbps. On the other hand, Cat 6 reaches even higher with a maximum of 10 Gbps up to 250 MHz. Cat 6 also has added shielding so you get less noise interferences, but the cables are thicker, taking up more space.

  • With different cabling standards available, it’s instinctive to go for the highest standard first. However, higher standards are more expensive to install, and they’re not as space-saving.

    Regular internet connections can be perfectly serviced by Cat 5e cables, so it’s often the default choice. For more intensive data needs like constant video streaming or heavy processing, you can look into Cat 6, while even higher data standards like Cat 7 and Cat 8 are usually only for large enterprises.

    Consider how much data your network will be handling and the desired speed as well as the space for the cables and your budget.

  • The most common data network faults are slow speeds, dropped internet connections, individual devices being unable to connect, and weak wifi signals.

    Problems with the internet connection can be caused by too much demand on the network or by faulty components or wiring. Environmental interference such as leaked radiation from microwaves can also affect this.

    Proper installation and maintenance will minimise data network faults and keep them optimised for new technology.
