Network patch cable bkl electronic CAT 8.1 S/FTP RJ45 15 m halogen-free — black

bkl electronic CAT 8.1 S/FTP RJ45 patch cable, 15 m, halogen-free and black, provides a shielded copper connection for high-speed Ethernet links. The S/FTP construction (overall braid plus individually shielded pairs) reduces crosstalk and electromagnetic interference, making this cable suitable for demanding LAN environments, data center interconnects and structured cabling where stable 25/40 Gbps and lower-speed links are required. The halogen-free jacket limits toxic gas emission in case of fire and the standard RJ45 terminations allow plug-and-play connection to switches, routers and servers.

Advantages

The cable combines CAT 8.1 performance with S/FTP shielding to provide improved noise immunity and stable throughput across its 15 m length. Its halogen-free outer sheath increases safety in enclosed spaces by reducing harmful fumes if exposed to high temperatures. The black jacket offers a neutral appearance for rack and floor installations, and RJ45 terminations ensure compatibility with common networking equipment.

Suitable for

• High-performance LAN links in offices and server rooms
• Data center patching between switches and servers
• Structured cabling backbones and horizontal runs up to 15 m
• Applications requiring reduced crosstalk and EMI for reliable 25/40 Gbps and lower-speed connections

When it may not be suitable

This CAT 8.1 patch cable is designed for short to medium runs and structured installations; it is not intended as a substitute for permanent in-wall infrastructure that may require different cable types or installation practices. For runs exceeding 15 m or for specific outdoor, direct-burial, or plenum-rated installations, select a cable specified for those environments.

Key specifications

• Category: CAT 8.1
• Shielding: S/FTP (overall braided shield with individually shielded pairs)
• Connector type: RJ45 male to RJ45 male
• Length: 15 m
• Jacket material: Halogen-free
• Color: Black
• Suitable data rates: up to 25/40 Gbps and lower speeds depending on equipment

How to use

Connect one RJ45 end to your network switch, router or patch panel and the other end to the target device such as a server, workstation or another switch. Ensure connectors are fully inserted until the latch clicks. Keep the cable routed to avoid sharp bends and excessive tension; maintain the recommended bend radius to preserve signal integrity. For optimal performance, avoid running the cable parallel and close to high-power electrical lines or sources of strong electromagnetic interference.

What to consider before purchase

• Required cable length and whether 15 m is sufficient for your run
• Environmental requirements such as indoor use, plenum rating, or outdoor exposure
• Compatibility with your network equipment and support for desired data rates
• Cabling standards and installation practices for permanent or structured installs

Usage recommendations

For best results, use this CAT 8.1 S/FTP patch cable for short connections within racks and between adjacent network devices. Test link speed after installation and keep cable paths separate from high-voltage power runs to minimize interference.
