Network patch cable bkl electronic CAT 8.1 S/FTP RJ45, 3 m, halogen-free, black

Shielded S/FTP CAT 8.1 patch cable by bkl electronic with RJ45 connectors and a 3 m halogen-free black jacket. Engineered for short-distance high-speed Ethernet links, this cable provides enhanced shielding to reduce electromagnetic interference and crosstalk. It is suitable for server racks, switches and professional network installations that require reliable, low-noise connections and support for next-generation 25/40 Gbps-ready deployments over short runs.

Advantages

The S/FTP construction combines an overall foil shield with individual pair shielding to provide superior protection against external interference and internal crosstalk. The halogen-free outer jacket reduces the emission of toxic gases in case of fire and meets safety preferences for data centre and commercial environments. RJ45 connectors ensure compatibility with common networking equipment while the 3 m length offers flexibility for rack-to-rack or cabinet-to-switch connections without excess cable slack.

Suitable for

• Short-distance 25/40 Gbps-ready links within data centres and server rooms
• Patch panels, network switches and server rack interconnections
• Professional installations where reduced electromagnetic interference is needed
• Environments requiring halogen-free cabling for safety regulations

When it may not be suitable

This 3 m CAT 8.1 patch cable is intended for short-distance, high-performance connections; it is not designed for long horizontal cabling runs where fiber or lower-category copper with longer reach might be more appropriate. It may also be more advanced than required for basic home networking where Cat5e/Cat6 cables suffice and where the additional shielding and cost are unnecessary.

Key specifications

• Cable category: CAT 8.1 (S/FTP shielding)
• Connector type: RJ45 on both ends
• Length: 3 m
• Jacket: halogen-free, black
• Use case: supports short-distance high-speed Ethernet (25/40 Gbps-ready)
• Shielding: overall foil plus individually shielded pairs

How to use

Connect one RJ45 plug to the network switch or patch panel port and the other RJ45 plug to the server, router or destination port. Ensure both ports support the intended speed and that connectors are fully inserted and latched. Route the cable with gentle bends, avoiding sharp kinks and excessive tension. For installations in racks or conduits, allow adequate bend radius and avoid tight bundling with power cables to maintain shielding effectiveness.

What to consider before purchase

• Confirm required cable length and whether 3 m is appropriate for your rack or equipment layout
• Verify that connected devices and ports support higher-speed operation if you plan to use 25/40 Gbps-capable links
• Check whether halogen-free jacket and S/FTP shielding are required by site safety or electromagnetic compatibility policies

Usage recommendations

Use this CAT 8.1 S/FTP 3 m patch cable for short, high-performance links inside racks and cabinets. Maintain proper bend radius, avoid electromagnetic noise sources when routing, and test link performance after installation to confirm expected throughput and signal integrity.
