What is Network Cabling?

Network cabling refers to wires, cables, and other hardware that allows various network devices to connect and communicate within an IT infrastructure. It is the physical transmission medium for data, voice, multimedia, and other signals between computers, servers, and other network-enabled devices.

The role of network cabling in connectivity is crucial, as it carries essential information throughout an organisation, similar to how veins and arteries transport blood in the human body. A well-designed and correctly installed network cabling system ensures data flows efficiently, with minimum interference and maximum bandwidth.

This system supports surveillance systems that keep facilities safe and the everyday functions of internet access and data transfer that businesses depend on.

Why is Network Cabling Important?

In an office environment, having a reliable network cabling system is crucial for maintaining a solid connection that supports various applications, such as emails, database access, file sharing, online collaboration, and VoIP services.

  • Proper cabling infrastructure is essential for minimising downtime and ensuring high-speed data transmission, directly impacting productivity and operational success.
  • Quality cabling solutions are designed to accommodate future expansion. As a business grows, its network infrastructure must adapt to new technologies and increased traffic without requiring a complete system overhaul.
  • High-quality cabling can support this scalability, ensuring a longer lifespan of the network infrastructure.

What are the Different Types of Network Cables?

The world of network cabling is vast, and each cable type offers unique characteristics suitable for different networking requirements. Here is an overview of some of the commonly used network cables:

Fiber Optic Cables:

These cables use glass fibres to transmit data as light, making them ideal for long-distance and high-speed data transmission. They are immune to electromagnetic interference, thus ensuring a clearer signal over great distances without degradation.

Pros: High bandwidth capacity, excellent for long distances, secure from interference and eavesdropping.

Cons: They are typically more expensive to install, require specialised equipment for termination, and are more fragile than copper cables.

Coaxial Cables (e.g., RG59):

Once the standard for data and video transmission, coaxial cables are still used for certain types of CCTV installations and cable internet services.

Pros: Inexpensive and relatively resistant to signal interference, durable, and can be used over moderate distances.

Cons: Lower bandwidth compared to fibre, not suitable for modern high-speed networks, and can be bulky.

CAT5 Cables:

Category 5 cables are older Ethernet cables, typically used for networks that do not require high data transfer speeds. They support up to 100 Mbps.

Pros: Cost-effective, sufficient for small-scale or older installations, and does not require high bandwidth.

Cons: Limited bandwidth, unsuitable for modern applications demanding higher data speeds, and mainly obsolete.

CAT6 Cables:

An advancement over CAT5, these cables support gigabit speeds and can transmit up to 10 Gbps over short distances (up to 55 meters).

Pros: It has a higher bandwidth than CAT5, can handle more network traffic and higher speeds, and is backwards compatible with CAT5.

Cons: More expensive than CAT5, installation can be more complex due to stricter specifications for shielding and crosstalk.

CAT6a Cables:

The ‘a’ stands for ‘augmented’, and these cables support twice the maximum bandwidth and can maintain higher transmission speeds over longer cable lengths.

Pros: Supports bandwidth frequencies up to 500 MHz, is better at reducing crosstalk, and can handle 10G network speeds up to 100 meters.

Cons: Bulkier than CAT6 due to additional shielding, more expensive, and may require more space in conduits.

How Do You Choose the Right Network Cable?

When choosing network cables, several factors must be considered, such as the required bandwidth, budget, the distance of the cable runs, and the potential for interference. Fibre optic cables are the best option for long-distance, high-speed transmissions.

  • CAT6 or CAT6a cables are excellent for high-speed data transfer in an office environment.
  • For surveillance purposes, especially when using Hikvision cameras, coaxial cables like RG59 may still be relevant for specific analogue installations.
  • However, for digital IP camera systems, it’s preferable to use network cablings such as CAT5e, CAT6, or fibre optics, which offer higher data capacity and excellent reliability.
  • If you use Hikvision cameras for surveillance, coaxial cables like RG59 may still be relevant for specific analogue installations. However, due to their higher data capacity and reliability, network cabling like CAT5e, CAT6, or fibre optics would be preferable for digital IP camera systems.

What are some Common issues associated with Network Cabling?

Network cabling issues are common in CCTV installations that use Hikvision equipment. These issues can vary widely but usually revolve around a few key areas. If you want to maintain the reliability and performance of your surveillance system, it’s important to troubleshoot these issues effectively.

Network Cabling FAQ

Q: What should I do if my cables are damaged by rodents, crushed, or showing wear and tear?

A: Inspect the entire length of your cable for visible damage. If damage is found, you may need to replace the damaged section or the whole cable. To protect cables in vulnerable areas, consider using cable guards or conduits.

Q: How can I resolve connectivity issues caused by improperly terminated or loose connections?

A: Check all cable terminations at both ends to ensure they’re correctly crimped. Using a cable tester can help verify connection integrity. If any connections fail, re-terminate them. Always use high-quality connectors that match your cable’s specifications.

Q: What should I do if I suspect signal degradation due to the length of my Ethernet cables?

A: Measure the cable length and compare it to the maximum recommended length of 100 meters for Cat5e/Cat6 cables to avoid signal degradation. If it exceeds this limit, consider installing a network switch or signal repeater to boost the signal.

Q: How can I minimise electromagnetic interference (EMI) affecting my cables?

A: Reroute cables away from EMI sources or use shielded twisted pair (STP) cables for better protection than unshielded (UTP) cables. Ensure the shield is grounded correctly to mitigate interference.

Q: What if I’ve used the wrong cable type for my CCTV setup?

A: Ensure you use the correct cable type for your specific needs. For Power over Ethernet (PoE) cameras, use Cat5e or higher cables. For analogue cameras, use the appropriate coaxial cable and keep within the maximum signal length of 150 meters.

Q: How can I address crosstalk affecting my network performance?

A: Use high-quality, twisted-pair Ethernet cables designed to minimise crosstalk. Maintain proper cable organisation and avoid tightly bundling cables together for extended runs.

Q: What precautions should I take against environmental factors degrading cable performance?

A: Use cables rated for the specific environmental conditions they’ll face. For outdoor installations, opt for cables rated for outdoor use that can withstand moisture, temperature variations, and UV exposure.

How Do You Maintain Your Network Cables?

To maintain your network cables effectively, especially in CCTV systems using Hikvision equipment, it is essential to follow these concise tips to ensure longevity and reliability:

  • Maintaining your cables in good condition is essential to preventing potential damage or issues.
  • Use cable organisers to reduce stress on your cables.
  • Avoid overstretching.
  • Label both ends of your cable.
  • Periodically check for physical damage, use the right tools, and protect your cables in harsh environments.
