Cat 5e, Cat 6, Cat 6a, Cat 7 & Cat 8 Network Cabling: Choosing the Right Infrastructure for Your Business

In today's digital world, your network cabling infrastructure is the foundation of your business connectivity. From computers and printers to VoIP phones, CCTV systems, WiFi access points, and cloud applications, every connected device relies on a high-quality cabling system to deliver reliable performance.

At Morecom Ltd, we design, install, test, and certify structured cabling solutions for businesses across a wide range of industries. As Excel Partner Installers, having completed accredited training through Mayflex, we can provide professionally installed structured cabling systems backed by manufacturer certification and, where required, a 25-year Excel System Warranty through full testing and certification of the installed infrastructure.

Why Structured Cabling Matters

A structured cabling system is an investment that often remains in place for 10 to 20 years or more. While network switches, servers, and computers are regularly upgraded, the underlying cabling remains the backbone of the network.

Choosing the correct cable category ensures:

• Reliable network performance
• Higher data transfer speeds
• Improved support for cloud applications
• Better Power over Ethernet (PoE) delivery
• Reduced downtime
• Future-proofing against new technologies
• Increased property and infrastructure value

Cat 5e Cabling

Category 5e (Cat 5e) remains one of the most common cabling standards found in existing commercial buildings.

Performance

• Supports speeds up to 1 Gigabit Ethernet (1Gbps)
• Maximum cable length of 100 metres
• Suitable for frequencies up to 100MHz

Advantages

• Cost effective
• Proven reliability
• Supports IP phones and CCTV systems
• Suitable for basic office networking

Best Applications

• Small offices
• Home offices
• Basic broadband connectivity
• Legacy network upgrades

Whilst Cat 5e continues to perform well for many applications, businesses planning for high-performance networking should consider newer standards.

Cat 6 Cabling

Category 6 (Cat 6) offers improved performance over Cat 5e and has become a popular choice for commercial installations.

Performance

• Supports 1Gbps up to 100 metres
• Supports 10Gbps up to approximately 55 metres
• Frequency rating of 250MHz

Advantages

• Improved bandwidth
• Reduced crosstalk
• Better signal performance
• More suitable for modern networking equipment

Best Applications

• Office networks
• Education facilities
• Retail environments
• Small server rooms
• Business WiFi deployments

Cat 6 remains an excellent solution for many businesses seeking a balance between performance and budget.

Cat 6a Cabling

Category 6a (Augmented Category 6) has become the preferred choice for many modern commercial installations.

Performance

• Full 10 Gigabit Ethernet support
• Maximum distance of 100 metres
• Frequency rating of 500MHz

Advantages

• Supports future network growth
• Ideal for multi-gigabit networking
• Enhanced protection from interference
• Greater long-term investment value

Best Applications

• New office developments

• Server and communications rooms

For most new business installations, Morecom Ltd typically recommends Cat 6a because it provides the ideal balance between performance, longevity, and cost.

Cat 7 Cabling

Category 7 (Cat 7) was introduced to offer higher performance and additional shielding.

Performance

• Supports speeds up to 10Gbps
• Frequency rating of 600MHz
• Enhanced shielding on individual pairs

Advantages

• Excellent protection against interference
• Improved signal integrity
• Designed for electrically noisy environments

Best Applications

• Manufacturing facilities
• Industrial environments
• Specialist installations

Considerations

Although Cat 7 offers enhanced shielding, it has seen limited adoption within standard commercial infrastructure due to compatibility considerations and higher installation costs.

Cat 8 Cabling

Category 8 (Cat 8) is currently the highest-performing copper Ethernet standard available.

Performance

• Supports speeds up to 25Gbps and 40Gbps
• Frequency rating of 2000MHz
• Maximum recommended distance of 30 metres

Advantages

• Extremely high throughput
• Low latency performance
• Ideal for demanding network environments

Best Applications

• Data centres
• Server-to-switch connections
• Enterprise computing environments
• High-density IT infrastructure

For general office environments, Cat 8 is often unnecessary, but it can be invaluable within specialist networking applications.
