Network patch cable bkl electronic 144021 CAT 8.1 S/FTP RJ45, halogen-free, 5 m, black

Shielded S/FTP CAT 8.1 RJ45 patch cable bkl electronic 144021 is a halogen-free, 5 m long network patch cable in black designed for high-performance short-run Ethernet and data centre connections. The cable combines foil and braid shielding to reduce electromagnetic interference and crosstalk, and uses an RJ45 connector to interface with standard switches, patch panels and server ports. It is intended for installations that require improved noise immunity and reliable signal transmission at high data rates.

Advantages

The shielded S/FTP construction provides enhanced protection against external interference compared with unshielded cables, helping to maintain signal integrity in electrically noisy environments. Halogen-free materials reduce toxic gas emissions in case of fire and meet requirements for installations where low smoke and toxicity are desirable. The 5 m length offers flexibility for rack-to-rack or equipment-to-patch-panel connections while keeping attenuation low for short-distance, high-speed links.

Suitable for

• Short-run Ethernet connections in data centres and server rooms
• Patch panel to switch or server connections in rack installations
• Professional network environments requiring shielded cabling for reduced interference
• High-speed links where CAT 8.1 performance and RJ45 compatibility are required

When it may not be suitable

This CAT 8.1 S/FTP patch cable is optimized for short distances; it is not intended for long horizontal runs where attenuation and cable cost become limiting factors. For environments that do not experience significant electromagnetic interference or where shielding is unnecessary, an unshielded cable may be more cost-effective and easier to terminate.

Key specifications

• Category: CAT 8.1 (shielded)
• Shielding: S/FTP (overall braid + individual foil for pairs)
• Connector type: RJ45
• Length: 5 m
• Colour: Black
• Material properties: Halogen-free
• Intended use: High-speed Ethernet and data centre connections over short distances

How to use

Plug the RJ45 connectors into the corresponding ports on network switches, patch panels or servers. Ensure that connected equipment supports shielded cabling and that chassis and patch panels are properly grounded to take full advantage of the S/FTP shielding. Route the cable without sharp bends and avoid running parallel to power cables where possible to minimise residual interference. For rack installations use cable management panels or ties to maintain neat routing and prevent stress on connectors.

What to consider before purchase

• Verify that your network devices and infrastructure support and benefit from shielded cabling and proper grounding.
• Confirm that a 5 m length fits your rack or equipment layout to avoid excess slack or insufficient reach.
• Assess whether CAT 8.1 short-run performance is necessary for your application or if a lower category would suffice.

Usage recommendations

For optimal performance, use this S/FTP CAT 8.1 RJ45 patch cable for short, high-speed connections inside data centres and server racks, ensure proper grounding of shielded components, and maintain gentle bend radii and organised cable management to preserve signal quality and connector integrity.
