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 Halogen-Free, Black is a short, shielded Ethernet patch cable designed for high-frequency, short-range connections in professional network environments. The cable follows Category 8.1 performance parameters and uses an S/FTP (shielded foil twisted pair) construction to reduce electromagnetic interference and crosstalk. With a compact 0.5 m length and a halogen-free black jacket, it is intended for use in data centers, server racks and dense LAN installations where reliable high-speed links are required between nearby equipment.

Advantages

The S/FTP construction provides enhanced EMI protection, improving signal integrity in electrically noisy environments. Its Category 8.1 performance supports very high data rates and elevated frequency ranges compared with lower-category cables, which helps future-proof short patch connections. The halogen-free jacket reduces the risk of toxic gas emissions in the event of fire, making the cable suitable for installations with stricter fire-safety requirements. The short 0.5 m length minimizes excess cable clutter in patch panels and rack-mounted equipment.

Suitable for

• Short-distance connections between servers, switches and patch panels in data centers
• High-speed uplinks and cross-connects inside server racks
• Professional LAN setups where shielding and reduced crosstalk are required
• Environments with fire-safety considerations that prefer halogen-free cabling

When it may not be suitable

This 0.5 m patch cable is intended for short, direct connections; it is not suitable for long-distance runs or general in-room cabling where longer lengths are needed. If your installation does not require full Cat 8.1 performance or S/FTP shielding, a lower-category or unshielded cable may be a more cost-effective choice.

Key specifications

• Category: Cat 8.1 performance class
• Shielding: S/FTP (overall braid plus individually shielded pairs)
• Length: 0.5 m
• Connector: RJ45 at both ends
• Jacket: Halogen-free, black
• Application: Short-range, high-frequency Ethernet patching

How to use

Connect each RJ45 plug to the corresponding port on your network devices, such as switch-to-switch, switch-to-server or patch-panel-to-switch links. Ensure connectors are fully seated and routed without sharp bends to preserve shielding and pair performance. Use the 0.5 m length to create tidy, short patch runs in racks and panels; avoid stretching the cable or forcing it through narrow gaps that could damage the jacket or connector boots.

What to consider before purchase

• Required cable length for your rack or patch-panel layout (0.5 m is for short connections)
• Whether Cat 8.1 performance and S/FTP shielding are necessary for your equipment and environment
• Compatibility of RJ45 ports on existing devices with Cat 8.1 shielded cabling
• Fire-safety or building-code requirements that make halogen-free jackets preferable

Usage recommendations

For optimal performance, use this Cat 8.1 S/FTP patch cable for short, direct connections inside racks and patch panels. Keep cable runs short and avoid sharp bends; verify grounded equipment and proper installation practices to maintain shielding effectiveness.
