Network Cabling Explained: The Common Types Of Cabling

Network Cabling

As businesses increasingly rely on advanced technology solutions to drive growth and efficiency, the importance of a solid network infrastructure has never been more critical.

Wired networks remain foundational to corporate IT, providing reliable, high-speed connections that wireless networks can’t fully replace.

In this article, we will explain the array of network cabling options that are best suited for business environments, examining their advantages, disadvantages, and best-use scenarios.

Copper-Based Cabling Systems

Twisted Pair Cabling (Cat 5e, Cat 6, Cat 7)

Twisted pair cables are a mainstay in business networking.

Categories such as Cat 5e, Cat 6, and Cat 7 offer different speeds and are useful for various business applications like VoIP phones, data centers, and video conferencing.


  • Cost-Effectiveness: These cables are generally less expensive compared to other types, making them ideal for small to medium-sized businesses.
  • Ease of Installation: Twisted pair cables are relatively straightforward to install, saving time and reducing costs.


  • Distance Limitation: These cables usually have a maximum effective range of 100 meters, beyond which signal repeaters are needed.
  • Susceptibility to Interference: Twisted pair cables can be vulnerable to electromagnetic interference if not properly shielded.


Coaxial Cables

Coaxial cables are less commonly used in modern business environments but are still relevant for certain legacy systems and specialised applications.


  • Durability: These cables are robust and can resist some forms of interference.
  • Longer Distance: Coaxial cables can sometimes be effective for distances over 100 meters.


  • Inflexibility: Coaxial cables are less flexible, making them less ideal for complex routing.
  • Phasing Out: Many businesses are moving away from coaxial cables, making them less of a future-proof option.

Optical Fibre Cabling Systems

Single-Mode Fibre

These are ideal for long-distance, high-bandwidth applications and are often employed in enterprise-level backbone networks.


  • High Data Throughput: Single-mode fibre cables can handle a significant amount of data, often reaching Gbps speeds.
  • Long-Distance Capabilities: These cables are ideal for connections spanning several kilometres.


  • High Costs: The initial investment for single-mode fibre can be quite high, including the cabling itself and compatible networking hardware.
  • Complex Installation: Installation usually requires specialised skill sets and equipment


Multi-Mode Fibre

Multi-mode fibre is suitable for short to medium distances and finds usage in internal business network architectures, like within a campus or a large office building.



  • High Bandwidth: Excellent for carrying a large amount of data over short distances.
  • Lower Costs: Generally less expensive than single-mode for the hardware and components.


  • Limited Distance: Effective usually up to a range of 600 meters, making it less ideal for long-range connectivity.
  • Higher Attenuation and Dispersion: This can result in signal quality degradation over distance.


Specialised Business Cabling Solutions

InfiniBand is often used in high-performance computing environments like data centres due to its extremely high data throughput capabilities.


  • Ultra-High Speed: Speeds can reach up to hundreds of Gbps, ideal for applications that require rapid data transfer.
  • Low Latency: Excellent for tasks that require real-time processing.


  • High Costs: InfiniBand solutions are expensive to implement and maintain.
  • Limited Application: Overkill for most typical business applications.

Direct Attach Copper (DAC)

DAC is commonly used in data centres for short-range connections between servers and storage devices.


  • High-Speed Short Links: Ideal for connecting hardware that is physically close.
  • Cost-Effective: Less expensive than fibre optics for short distances.


  • Limited to Data Centres: Generally not suitable for broad business networking needs.
  • Short Distance: Usually effective up to only about 7 to 10 meters.


Our Final Word

Selecting the appropriate type of network cabling is a pivotal decision for any business, but you don’t have to make that decision – that’s what we are here for.

While twisted pair cables like Cat 5e and Cat 6 are often adequate for small to medium businesses, larger enterprises may benefit more from fibre optic solutions.

Specialised cabling solutions like InfiniBand and DAC are more niche but provide unparalleled performance in high-demand scenarios.

By understanding the advantages and disadvantages of each type, businesses can make an informed choice that best suits their operational needs, scalability plans, and budget constraints.
