Network patch cable bkl electronic CAT 8.1 S/FTP RJ45 1.5 m halogen-free black

bkl electronic CAT 8.1 S/FTP RJ45 patch cable, 1.5 m in length and halogen-free black jacket, is designed for high-speed Ethernet and professional network environments. The cable supports S/FTP shielding (individually foil‑shielded pairs plus overall braided shield) to minimise crosstalk and external interference, enabling stable high-throughput links in LANs, server rooms and data centres. With standard RJ45 terminations it connects patch panels, switches and network devices for demanding installations requiring up to 40 Gbps-capable transmission over short channel lengths.

Advantages

The cable provides high shielding effectiveness thanks to S/FTP construction, improving signal integrity in electrically noisy environments. The halogen-free jacket reduces toxic gas emission in case of fire and the robust outer sheath offers mechanical protection while remaining flexible for rack and patch panel routing. Standard RJ45 plugs ensure compatibility with common networking hardware and the 1.5 m length is suitable for neat, short-distance patching between equipment in racks and on desks.

Suitable for

• Patching between switches, patch panels and servers in data centres and server rooms
• High-speed LAN connections where reduced interference is required
• Professional network racks and structured cabling systems
• Environments requiring halogen-free cabling for safety or regulatory reasons

When it may not be suitable

This 1.5 m patch cable is intended for short-distance connections within racks or between nearby devices; it is not designed for long horizontal runs in building backbone cabling. The CAT 8.1 specification is optimised for data centre and professional use — for simple home networking or applications that do not require shielding or very high throughput, CAT 5e/CAT 6 cables may be more cost-effective.

Key specifications

• Category: CAT 8.1
• Shielding: S/FTP (foil on each pair + overall braided shield)
• Connector type: RJ45
• Length: 1.5 m
• Jacket: Halogen-free, black
• Suitable for: Up to 40 Gbps-capable links over short channel lengths (per CAT 8.1 application)

How to use

Connect one RJ45 plug to a network device such as a switch, patch panel or server NIC and the other end to the corresponding port on the paired device. Route the cable to avoid sharp bends and keep it clear of high-power electrical sources to preserve shielding effectiveness. Use appropriate cable management in racks or under desks to maintain bend radius and reduce strain on connectors for reliable long-term operation.

What to consider before purchase

• Required cable length for your rack or workspace — 1.5 m is for short patching only
• Whether shielded cable is needed for your environment and devices
• Compatibility of connected devices with RJ45 and CAT 8.1 characteristics
• Local fire-safety or building regulations regarding halogen-free cabling

Usage recommendations

For best performance, use this CAT 8.1 S/FTP patch cable in shielded installations with compatible shielded ports, maintain recommended bend radii, and pair with certified patch panels and switches to achieve reliable high-speed links in data centre and professional networking environments.
