Product information

Description

The EFB Elektronik K5528BL.0.5 is a 0.5 m Cat8.1 S/FTP patch cable with RJ45 connectors on both ends, designed for high-speed Ethernet links. It supports data rates up to 40000 Mbit/s and is built for applications requiring high bandwidth and reduced electromagnetic interference. The cable is blue and intended for short-distance, high-frequency network connections.

Advantages

The Cat8.1 construction with S/FTP shielding provides improved protection against crosstalk and external interference while supporting frequencies up to 2000 MHz. With RJ45 terminations it is compatible with standard 25GBASE-T and 40GBASE-T equipment where a maximum link length of 30 m is acceptable. Its 0.5 m length makes it suitable for patching in racks and connecting adjacent devices with minimal excess cable.

Suitable for

25GBASE-T links using RJ45
40GBASE-T short-reach connections
High-density rack patching and adjacent device connections
Environments requiring S/FTP shielding to reduce interference

How to use

Plug each RJ45 connector into the corresponding network ports on your devices or patch panel. Use the 0.5 m cable for short connections inside racks or between adjacent equipment. Ensure connectors are fully seated to maintain contact integrity.

Use this Cat8.1 S/FTP 0.5 m cable for short, high-speed RJ45 connections such as 25GBASE-T or 40GBASE-T patching within racks; avoid using it for runs exceeding the recommended 30 m maximum distance for Cat8.1 to ensure specified performance.
