Network Patch Cable bkl electronic 144022 RJ45 CAT 8.1 S/FTP 0.5 m Halogen-free Black

bkl electronic 144022 is a 0.5 m RJ45 patch cable manufactured to CAT 8.1 specifications, with S/FTP shielding and a halogen‑free black jacket. It is intended for short links in high‑speed Ethernet environments such as data centers and server racks, providing improved electromagnetic interference protection and stable signal transmission for multigigabit and 10G+ networks.

Advantages

The S/FTP construction delivers foil shielding around each twisted pair plus an overall braid, reducing crosstalk and external EMI for consistent throughput. The halogen‑free jacket lowers toxic gas emissions in case of fire and is suitable where enhanced fire safety is required. With a compact 0.5 m length and robust RJ45 connectors, this cable minimizes excess slack in rack environments and supports reliable, low‑latency links for high‑density installations.

Suitable for

• Short interconnects within server racks and patch panels
• High‑speed Ethernet links up to and beyond 10 Gbps in short runs
• Environments requiring improved EMI protection, such as dense cable bundles
• Installations where halogen‑free materials are mandated for safety

When it may not be suitable

This 0.5 m patch cable is not intended for long‑distance backbone runs or connections that require flexible, extended lengths; using it beyond its short‑link purpose will require additional longer cables. It is optimized for short, high‑performance links and may be excessive for basic home networking tasks where lower category cables and unshielded types are sufficient.

Key specifications

• Connector type: RJ45 to RJ45
• Category: CAT 8.1
• Shielding: S/FTP (overall braid + foil around each pair)
• Length: 0.5 m
• Jacket material: halogen‑free
• Color: black

How to use

Plug one RJ45 connector into the network port of a switch, server, or patch panel and the other connector into the corresponding port to establish a direct Ethernet link. Ensure both connected ports support the intended speed and duplex settings. Route the cable to avoid sharp bends and strong mechanical stress; maintain recommended bend radius to preserve shielding and pair geometry. For optimal performance in rack environments, use appropriate cable management to prevent compression or excessive twisting.

What to consider before purchase

• Verify required cable length — 0.5 m is for short, direct connections only
• Confirm the connected devices support the desired Ethernet speeds and shielding requirements
• Check whether halogen‑free jacket is required by building or safety regulations

Usage recommendations

Use this CAT 8.1 S/FTP 0.5 m patch cable for short, high‑density rack connections where shielded cabling and halogen‑free materials are preferred. Keep runs short and manage cables neatly to retain signal integrity and EMI protection.
