Network patch cable bkl electronic 144036 RJ45 Cat 8.1 S/FTP 1.5 m halogen-free black

Network patch cable bkl electronic 144036 RJ45 Cat 8.1 S/FTP 1.5 m halogen-free black is a shielded Ethernet cable designed for high-speed data transmission in professional LAN and data centre environments. The cable uses Cat 8.1 specification and S/FTP (overall braid with individually shielded twisted pairs) construction to reduce electromagnetic interference and crosstalk. With a 1.5 m length and halogen-free outer jacket in black, it is intended for short horizontal or rack-to-equipment connections where signal integrity and safety are priorities.

Advantages

The S/FTP construction provides enhanced protection against external electromagnetic interference and pair-to-pair crosstalk, which helps maintain stable throughput for high-frequency Ethernet links. The Cat 8.1 rating supports high bandwidths required by modern switches and servers, while the halogen-free jacket reduces harmful emissions in case of fire and is suitable for use in enclosed or public spaces. The 1.5 m length is convenient for tidy rack installations and short patching runs.

Suitable for

• Short connections between patch panels, switches and servers in racks
• High-speed Ethernet links in data centres and server rooms
• LAN installations requiring improved shielding and reduced interference
• Environments where halogen-free cabling is preferred for safety

When it may not be suitable

This cable is optimized for short-distance, high-performance connections; it may not be necessary for basic home networking or long cable runs where Cat 6 or Cat 6a cables already meet requirements. For outdoor installations, direct burial, or runs requiring specific UV or weather resistance, choose a cable specifically rated for those conditions. If you require a different length or a non-shielded cable type, consider alternative products.

Key specifications

• Category: Cat 8.1
• Shielding: S/FTP (overall braid with individually shielded pairs)
• Connector type: RJ45
• Length: 1.5 m
• Outer jacket: halogen-free
• Colour: black
• Recommended use: short-range, high-frequency Ethernet connections

How to use

Connect one RJ45 plug to the network device (switch, patch panel, or server) and the other plug to the corresponding port on the device at the opposite end. Ensure connectors are fully seated to achieve proper contact and maintain shielding continuity. Route the cable through racks or cable management systems to avoid tight bends; maintain bend radius recommendations typical for high-frequency Ethernet cables. Test the link after installation with appropriate network testers to verify performance and correct wiring.

What to consider before purchase

• Verify that Cat 8.1 performance and S/FTP shielding are required for your equipment and network design
• Confirm 1.5 m length is appropriate for your rack or connection layout
• Check that RJ45 connectors and black colour match your existing infrastructure and aesthetic preferences
• Consider whether an outdoor- or UV-rated cable is needed for non-indoor use

Usage recommendations

For best results, use this Cat 8.1 S/FTP patch cable for short, high-speed links inside racks and equipment rooms; avoid excessive bending and maintain proper grounding of shielded systems to fully benefit from the cable's shielding.
