Cabo de rede EFB Elektronik K5528GN.1 RJ-45 Cat8.1 1 m verde

The EFB Elektronik K5528GN.1 is a 1 m Cat8.1 networking cable with RJ-45 connectors designed for high-speed copper Ethernet links. It supports 25GBASE-T and 40GBASE-T applications, offers a frequency range up to 2000 MHz and a maximum recommended transmission distance of 30 m. The cable uses S/FTP shielding and is finished in green.

Advantages

The Cat8.1 construction and S/FTP shielding reduce electromagnetic interference and crosstalk, enabling reliable data transmission at very high rates up to 40000 Mbit/s. Short length (1 m) minimizes signal loss for short-run connections while RJ-45 compatibility simplifies integration with existing network equipment. The cable conforms to Cat8.1 performance parameters including support for frequencies up to 2000 MHz.

Suitable for

• Short-run connections between high-speed switches and servers
• 25GBASE-T and 40GBASE-T copper links in data centres
• High-performance workstations and network appliances requiring low-interference cabling

How to use

Connect one RJ-45 plug to your switch, router or NIC port and the other RJ-45 plug to the target device. Ensure both network ports support the required 25G/40GBASE-T speeds or will negotiate the appropriate speed. Avoid tight bends and keep the cable clear of sources of strong electromagnetic interference. For permanent installations, route the cable according to site cabling standards and secure it to prevent strain on the connectors.

Recommendations

Use this 1 m Cat8.1 cable for short-distance, high-bandwidth copper links in rack environments or between adjacent devices. Verify device compatibility with 25GBASE-T/40GBASE-T over RJ-45 and follow data centre cabling guidelines for shielding continuity and connector protection.
