Networking cable EFB Elektronik K5528SW.1 RJ-45 Cat8.1 1 m Black

The EFB Elektronik K5528SW.1 is a 1 m RJ-45 patch cable conforming to the Cat8.1 standard. Designed for high-speed Ethernet links, the cable supports 25GBASE-T and 40GBASE-T applications, offers S/FTP shielding to reduce interference, and provides a frequency range up to 2000 MHz with a recommended maximum transmission distance of 30 m.

Advantages

This networking cable delivers data rates up to 40000 Mbit/s and uses S/FTP shielding to minimise electromagnetic interference. Equipped with RJ-45 connectors on both ends and a compact 1 m length, it is suitable for short, high-bandwidth connections where low latency and signal integrity are required. The black jacket provides a discreet appearance in rack or desktop installations.

Suitable for

• Short-distance high-speed links in data centres and server rooms
• 25GBASE-T and 40GBASE-T network connections
• Connections between switches, patch panels and high-performance network devices
• Environments requiring shielded cabling to reduce interference
