Network cable bkl electronic CAT 8.1 S/FTP RJ45 patch cable 5 m halogen-free, single unit

Shielded S/FTP CAT 8.1 RJ45 patch cable by bkl electronic, 5 m length, halogen-free, is designed for high-speed Ethernet links in professional networking environments. The cable features individually foil-shielded pairs and an overall shield to minimise crosstalk and electromagnetic interference (EMI), providing stable signal transmission for demanding applications that require Category 8.1 performance. The RJ45 connectors support standard 8P8C terminations and the cable construction is intended for use in data centres, server rooms and structured LAN installations where reduced interference and high bandwidth are required.

Advantages

The CAT 8.1 S/FTP construction delivers improved protection against external noise and pair-to-pair interference, which helps maintain higher signal integrity at elevated frequencies. A 5 m length offers flexibility for rack-to-rack or equipment-to-switch connections without excessive slack. The halogen-free jacket reduces harmful gases in the event of fire, making the cable suitable for environments with stricter safety requirements. Overall, the cable is built to support high-data-rate transmissions while keeping installation straightforward with standard RJ45 terminations.

Suitable for

• Short-distance, high-speed links in data centres and server rooms
• Connections between switches, patch panels and network appliances
• Professional LAN installations requiring reduced EMI and crosstalk
• Environments that prefer halogen-free cabling for safety compliance

When it may not be suitable

This CAT 8.1 S/FTP patch cable is optimised for short, high-bandwidth connections; it is not intended for long-run in-wall or outdoor installation where specific riser/plenum ratings or weatherproofing are required. For standard home networking where Cat5e or Cat6 performance is sufficient, this cable may be more capable than necessary and could be a higher-cost option.

Key specifications

• Category: CAT 8.1 (S/FTP)
• Shielding: Individually foil‑shielded pairs plus overall shield
• Connector: RJ45 (8P8C) terminations
• Length: 5 m
• Jacket: Halogen‑free
• Typical use: Short-range, high-frequency Ethernet links

How to use

Route the 5 m patch cable between network devices such as switches, patch panels and servers, ensuring connectors are fully seated in RJ45 sockets until a click is felt. Avoid sharp bends and excessive mechanical stress on the cable and secure it with appropriate cable management accessories to maintain bend radius and shielding integrity. For optimal performance, keep the cable separate from high-voltage power lines and sources of strong electromagnetic interference.

What to consider before purchase

• Required network category and whether CAT 8.1 performance is necessary for your application
• Installation environment and need for halogen‑free materials or specific fire ratings
• Required cable length and whether 5 m is appropriate for your layout
• Compatibility of RJ45 terminations with your devices and patch panels

Usage recommendations

Use this shielded CAT 8.1 S/FTP RJ45 patch cable for short, critical links where high bandwidth and reduced EMI are priorities; maintain proper bend radius, avoid parallel runs with power cables, and secure connections in patch panels or keystone jacks to preserve shielding and signal quality.
