Networking Cable Wentronic 55122 Cat8.1 S/FTP 0.25m White

The Wentronic 55122 Cat8.1 S/FTP networking cable is a short patch cable designed for high-speed data connections over short distances. At 0.25 m length and finished in white, it connects devices using standard RJ-45 interfaces while meeting Cat8.1 performance requirements. S/FTP shielding (overall foil plus individually shielded pairs) reduces electromagnetic interference and crosstalk, supporting reliable transmission in dense cabling environments. Gold-plated RJ-45 contacts improve contact reliability and resist corrosion for consistent signal transfer.

Advantages

The cable combines Cat8.1 performance with S/FTP construction to deliver improved noise immunity and reduced pair-to-pair interference compared with lower-category cables. Its short 0.25 m length is suitable for patching within racks, connecting adjacent network devices, or minimizing slack in compact setups. Gold-plated RJ-45 plugs provide durable contact surfaces for repeated insertions and stable connections. The white jacket offers a neutral appearance that integrates into office, data center, and home environments.

Suitable for

• Patching between network equipment in racks or patch panels where short connections are required
• Connecting switches, routers, or servers placed close together
• High-frequency applications that benefit from S/FTP shielding and Cat8.1 characteristics

When it may not be suitable

This 0.25 m cable is not intended for long runs; it is designed for short-distance patching only. For connections between rooms or across larger installations, a longer cable rated for the required distance should be chosen. Additionally, full Cat8 system performance depends on the complete link and supporting hardware; using this cable alone does not upgrade an entire network beyond the limits of other components.

Key specifications

• Category: Cat8.1
• Shielding: S/FTP (overall foil with individually shielded pairs)
• Connector type: RJ-45 to RJ-45 with gold-plated contacts
• Length: 0.25 m
• Color: White

How to use

Plug the RJ-45 connector into the network port of the first device and the other end into the corresponding port of the second device, ensuring secure seating of each connector. Use this short patch cable to link adjacent equipment in racks, join a device to a nearby switch or patch panel, or replace a damaged short lead. Avoid excessive bending or sharp kinks near the connector heads to maintain shielding integrity and transmission performance.

What to consider before purchase

• Required cable length for your application — 0.25 m is suitable only for short connections
• Compatibility of connected devices with RJ-45 interfaces and Cat8.1 characteristics
• Whether S/FTP shielding is necessary in your environment to reduce interference

Usage recommendations

Use the cable for short, high-quality patching tasks in racks or equipment clusters. Route the cable without tight bends, avoid placing it parallel and close to strong power sources for extended runs, and inspect connector seating after installation to ensure optimal contact.
