Cat5e vs Cat6 vs Cat6A: Which Ethernet Cable Should You Buy?

When shopping for Ethernet cables, you've probably seen terms like Cat5e, Cat6, and Cat6A. While they may look similar, each cable is designed for different network speeds, distances, and environments.

Choosing the right cable ensures your network performs reliably today and is ready for future upgrades.

What Is an Ethernet Cable?

An Ethernet cable is the physical connection that links devices such as computers, routers, switches, gaming consoles, smart TVs, and network storage devices to your network.

Unlike WiFi, Ethernet provides a stable, low-latency connection that is ideal for streaming, gaming, video conferencing, and business applications.

Cat5e (Category 5 Enhanced) remains one of the most widely used network cables.

Best for:

• Home networks

• Fibre installations

• Smart TVs

• Gaming consoles

• Basic office networking

Performance:

• Speeds up to 1 Gbps

• Maximum distance of 100 metres

For many homes, Cat5e is still more than capable of delivering excellent performance.

Cat6

Cat6 offers higher bandwidth and better protection against interference.

Best for:

• Small businesses

• Home offices

• High-speed fibre connections

• Multiple connected devices

Performance:

• Up to 10 Gbps over shorter distances

If you're installing new network cabling today, Cat6 is often the best balance between performance and affordability.

• Large businesses

• Server rooms

• Commercial installations

• Future-proof networking

Performance:

• 10 Gbps up to 100 metres
