Patch Cable bkl electronic 144032 RJ45 Cat 8.1 S/FTP 3 m Black Halogen-free

bkl electronic 144032 is a 3 m RJ45 patch cable certified Cat 8.1 with S/FTP shielding and a halogen-free black jacket. It is engineered for high-speed Ethernet links where reduced crosstalk, controlled return loss and improved signal integrity are required. The cable supports short-range, high-bandwidth connections in data centers, server racks and professional network environments that demand Category 8.1 performance in a flexible patched link.

Advantages

The S/FTP construction combines an overall braided shield with individually foil-shielded pairs to minimize electromagnetic interference and provide stable transmission in electrically noisy environments. Category 8.1 certification ensures support for multi-Gigabit and 25/40 Gbps short-range links when used within specified channel limits. A halogen-free jacket reduces toxic and corrosive gas emissions in case of fire, and the 3 m length offers a compact, flexible solution for rack-to-rack or patch-panel-to-switch connections.

Suitable for

• Data center patching between switches and servers within short channel distances
• Server rack cabling and top-of-rack connections
• High-bandwidth Ethernet links such as 10G, 25G or 40G over short runs where Cat 8.1 is required
• Environments requiring reduced electromagnetic interference and improved signal integrity

When it may not be suitable

This 3 m patch cable is intended for short-range connections and may not be appropriate for longer horizontal cabling runs or in-building backbone links that exceed Category 8.1 distance limits. It is not a replacement for fiber optic cabling in scenarios where very long distances or electromagnetic isolation are mandatory.

Key specifications

• Connector type: RJ45 on both ends
• Category: Cat 8.1
• Shielding: S/FTP (braided overall shield with individually foil-shielded pairs)
• Length: 3 m
• Jacket material: Halogen-free
• Color: Black

How to use

Connect the RJ45 plugs to corresponding RJ45 ports on network equipment such as switches, patch panels or servers, ensuring secure insertion until the plug latch clicks. Route the cable to avoid sharp bends and excessive tension; maintain bend radii recommended by the equipment vendor to preserve signal performance. For optimal results in data center deployments, use within the supported channel length for Cat 8.1 links and avoid running the cable parallel to heavy power lines that could introduce interference.

What to consider before purchase

• Verify that your network devices and the intended channel comply with Cat 8.1 requirements and support the target data rate
• Confirm that a 3 m length meets your rack or patching layout to avoid excess slack or the need for longer runs
• Assess whether shielded cabling is required in your environment and ensure proper grounding of equipment

Usage recommendations

Use the bkl electronic 144032 patch cable for short, high-bandwidth links in rack environments. Ensure proper cable management and grounding for shielded installations, and replace any cable that shows visible damage to the jacket or connectors to maintain signal integrity.
