bkl electronic RJ45 Patch Cable CAT 8.1 S/FTP 0.5 m, Halogen-free, Black

bkl electronic RJ45 Patch Cable CAT 8.1 S/FTP 0.5 m in black is a short, shielded Ethernet patch cord intended for high-speed network links and dense rack environments. The S/FTP construction provides individual foil shielding around each twisted pair plus an overall braided shield, which reduces electromagnetic interference and pair-to-pair crosstalk. The halogen-free jacket reduces hazardous emissions in case of fire, making this cable appropriate for use in professional installations and data center patching where safety and signal integrity are required.

Advantages

The CAT 8.1 S/FTP design supports very high bandwidths and improved far-end and near-end crosstalk performance compared with unshielded or lower-category cables. Its short 0.5 m length is optimized for patching between adjacent ports in switches and server panels, minimizing excess cable management and signal attenuation. The halogen-free outer jacket offers increased safety in enclosed technical spaces, and the black color gives a discreet appearance in standard rack installations.

Suitable for

• Patching between switches and servers in racks and cabinets
• Short horizontal or vertical patch runs in data centers
• High-speed Ethernet links where shielded cabling is required
• Environments where halogen-free materials are specified for safety

When it may not be suitable

This 0.5 m patch cable is intended for short interconnects; it is not designed for long-distance backbone runs or horizontal cabling over several metres. In environments where shielded cabling is unnecessary or where cost sensitivity favors unshielded Cat5e/Cat6 solutions, a CAT 8.1 S/FTP cable may be excessive.

Key specifications

• Category: CAT 8.1 (shielded)
• Shielding: S/FTP — overall braid plus foil per pair
• Length: 0.5 m
• Jacket: halogen-free
• Connector type: RJ45 (standard 8P8C)
• Color: black

How to use

Use this patch cable to connect adjacent ports on switches, patch panels, and servers. Insert the RJ45 plugs fully into matching ports until the retention clip clicks to ensure a secure connection. Avoid tight bends near the connector ends and do not exceed the recommended bend radius for shielded Ethernet cables. For best performance, keep connectors and equipment grounded where required by your installation guidelines to maintain shielding effectiveness.

What to consider before purchase

• Ensure CAT 8.1 and shielded cabling are compatible with your network equipment and grounding practices
• Confirm that a 0.5 m length fits your rack layout to avoid excess tension or slack
• Verify whether halogen-free jacket material is required by local safety codes or site policy

Usage recommendations

For optimal signal integrity, use this bkl electronic CAT 8.1 S/FTP patch cable for short, high-speed interconnects in shielded environments and maintain proper grounding and bend-radius discipline during installation.
