Ethernet Cable
Ethernet cables - also known as network or LAN cables - are essential for high-speed data transmission in both residential and industrial environments. These cables connect devices like PCs, routers, switches, and printers using RJ45 connectors. You can find more information in our ultimate Ethernet cable guide.
We offer a full range of cable categories including Cat5e, Cat6, Cat6a, Cat7, and Cat8, in lengths from patch leads to long-run constructions. Available in U/UTP, FTP, S/FTP, and LSZH variants to suit installation needs and signal integrity demands.
Types of Ethernet Cable
- Cat5e – Reliable for up to 1 Gbps over 100 m at 100 MHz Ideal for general office and home networks.
- Cat6 / Cat6a – Supports 10 Gbps (Cat6 up to ~55 m; Cat6a up to 100 m) with improved bandwidth.
- Cat7 – Shielded cables designed for environments needing high EMI resistance and 10 Gbps support.
- Cat8 – High-performance cables supporting 25–40 Gbps over short distances for ultra-fast backbone links.
Usage & Advantages
- Used widely in office networks, data centres, industrial LAN installations, and smart building systems.
- Using shielded or higher-category variants (Cat6a, Cat7/8) helps reduce crosstalk and interference in electrically noisy environments.
- Compatible with all standard RJ45 ports and switches - deal for structured cabling installations.
How to Choose the Right Ethernet Cable
- Speed & Distance Needs: Choose Cat6 for standard Gigabit installs; Cat6a/Cat7/8 for higher speeds or longer runs.
- Shielding Preference: Opt for FTP or S/FTP for environments with electrical interference or near machinery.
- Sheath Material: Consider LSZH for fire-rated installations or harsh site conditions.
- Connector Type: Most cables terminate with an RJ45 plug, check compatibility with hardware and patch panels.
