Networking Cable EFB Elektronik RJ45 Patchkabel Cat8.1 7.5m Black

The EFB Elektronik RJ45 Patchkabel Cat8.1 (7.5 m, black) is a high-performance networking cable designed for 25GBASE-T and 40GBASE-T applications using RJ45 connectors. The cable complies with Cat8.1 standards, offers S/FTP shielding for improved protection against electromagnetic interference, supports frequencies up to 2000 MHz and is suitable for short-distance high-speed links up to 30 m.

Advantages

The cable provides support for very high data rates (up to 40000 Mbit/s) and complies with Cat8.1 specifications for reliable performance in demanding network environments. S/FTP shielding and RJ45 connectors ensure stable signal transmission and reduced crosstalk. The 7.5 m length offers flexibility for rack-to-rack or cabinet-to-switch connections while maintaining the short maximum transmission distance required by the standard.

Suitable for

• Short-distance 25GBASE-T and 40GBASE-T links in data centers
• High-speed connections between switches, servers and patch panels
• Environments requiring shielded cabling to limit interference

How to use

Connect one RJ45 connector to the network switch, server or patch panel port and the other RJ45 connector to the corresponding device port. Ensure both ports support the intended speed (25GBASE-T or 40GBASE-T) and keep the cable run within the recommended maximum distance of 30 m. Avoid tight bends and do not route the cable near strong sources of interference despite its shielding.

Recommendations

For optimal performance, use this Cat8.1 patch cable only for short, high-speed links in compliant infrastructure; verify device compatibility with Cat8.1/40GBase-T or 25GBase-T standards and maintain proper cable management to prevent strain or kinking.
