Netwerkkabel EFB Elektronik K5528GE.5 RJ-45 Cat8.1 5 m Geel

The EFB Elektronik K5528GE.5 RJ-45 Cat8.1 networking cable is a 5 m S/FTP patch cable designed for high-speed copper Ethernet links. It supports Cat8.1 performance with a frequency range up to 2000 MHz and is suitable for 25GBASE-T and 40GBASE-T applications. The cable features RJ-45 connectors on both ends and a yellow jacket for easy identification.

Advantages

This Cat8.1 S/FTP cable provides a maximum data transfer rate up to 40000 Mbit/s and is optimized for short-distance, high-frequency transmissions up to 30 m. The S/FTP shielding reduces crosstalk and external interference, and the RJ-45 terminations ensure compatibility with standard Ethernet equipment. The yellow outer jacket improves visibility in rack and cable management environments.

Suitable for

• Server-to-switch or switch-to-switch links within data centers (up to 30 m)
• High-speed workstation connections requiring 25GBASE-T or 40GBASE-T
• Short copper runs where high bandwidth and reduced interference are required

How to use

Connect one RJ-45 plug to the Ethernet port of your switch, router or network interface and the other RJ-45 plug to the corresponding device. Ensure both ports support the desired 25GBASE-T or 40GBASE-T speed and verify link speed settings in network equipment if necessary. Route the cable to avoid sharp bends and sources of strong electromagnetic interference to maintain signal integrity.

Recommendations

For reliable 25G/40G performance, keep patch runs within the specified 30 m limit, use appropriate cable management to prevent kinks, and avoid running near high-voltage power lines or heavy electrical equipment. Confirm connector and port compatibility before deployment.
