Networking cable EFB Elektronik K5528GN.2 RJ-45 Cat8.1 2 m Green

The EFB Elektronik K5528GN.2 is a Cat8.1 RJ‑45 patch cable with a length of 2 m, designed for high‑speed copper Ethernet connections. It supports 25GBASE‑T and 40GBASE‑T applications, offers shielding in S/FTP construction to reduce electromagnetic interference, and provides a frequency range up to 2000 MHz with a recommended maximum transmission distance of 30 m.

Advantages

The cable meets the Cat8.1 standard and is rated for data rates up to 40 000 Mbit/s where supported by connected equipment. S/FTP shielding minimizes crosstalk and external interference, while standard RJ‑45 connectors ensure compatibility with common network ports. The 2 m length and green jacket make it suitable for short runs in racks, patch panels, or desktop connections.

Suitable for

• 25GBASE‑T and 40GBASE‑T copper Ethernet links
• Patch panels and cabinet short links (up to 30 m)
• High‑speed workstation or server connections

How to use

Connect one RJ‑45 plug to the network port of your switch, server or workstation and the other plug to the corresponding port on the opposite device or patch panel. Ensure both network interfaces support the intended 25G/40G operation and that cable runs do not exceed the recommended 30 m for Cat8.1 performance. Avoid sharp bends and mechanical stress on the connectors when routing the cable.

Recommendations

Use this Cat8.1 2 m cable for short, high‑speed copper links in racks or data centers. For runs longer than 30 m, consider fiber optic solutions or verify supported copper link budgets and equipment compatibility.
