Networking cable EFB Elektronik K5528RT.0.5 RJ-45 Cat8.1 0.5 m Red

The EFB Elektronik K5528RT.0.5 is a Cat.8.1 networking patch cable with a length of 0.5 m, designed for high-speed RJ45-based connections. 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 RJ-45 connectors, and is supplied in red.

Advantages

This Cat8.1 cable provides S/FTP shielding for improved protection against electromagnetic interference and crosstalk, enabling more reliable high-speed data transmission. Its compact 0.5 m length is suitable for short patching between devices, while RJ-45 connectors ensure compatibility with standard network ports. The cable meets the requirements for 25GBASE-T and 40GBASE-T performance within the specified distance.

Suitable for

• Short patch connections in server racks and network cabinets
• High-speed links between switches, routers and servers over RJ-45
• Data centre and telecom applications requiring up to 40 Gbit/s over copper within 30 m
• Environments where S/FTP shielding is required to reduce interference

How to use

Connect one RJ-45 connector to the network port of your switch, router or server and the other RJ-45 connector to the corresponding device port. Ensure connectors are fully inserted and latched. Use the cable for short links within the recommended 30 m distance to maintain the specified performance. Avoid sharp bends and mechanical stress on the cable and connectors during installation.

Recommendations

For optimum performance, use this Cat.8.1 S/FTP cable for short high-speed links in controlled rack or cabinet environments. Keep the cable free from tight bends and away from strong sources of electromagnetic interference; when routing near power lines or noisy equipment, maintain separation or use dedicated cable management to preserve signal integrity.
