Cabo de rede EFB Elektronik K5528RT.5 vermelho 5 m Cat8.1 S/FTP

The EFB Elektronik K5528RT.5 is a 5 m Cat8.1 S/FTP patch cable with RJ45 connectors designed for high‑speed copper Ethernet links. It supports 25GBASE‑T and 40GBASE‑T applications, provides a bandwidth up to 2000 MHz and is intended for short-distance connections up to 30 m.

Advantages

S/FTP shielding reduces crosstalk and external electromagnetic interference, supporting reliable high data rates up to 40000 Mbit/s. The RJ45 terminations ensure compatibility with standard network ports, and the distinct red jacket improves cable identification in patch panels and cable management systems.

Suitable for

• Short‑range 25GBASE‑T and 40GBASE‑T links (up to 30 m)
• Server rooms and data center patching
• High‑performance switches, NICs and aggregation points with RJ45 ports
• Environments requiring reduced electromagnetic interference

How to use

Connect each RJ45 plug to the corresponding RJ45 port on your devices (switch, server NIC or patch panel). Ensure connectors are fully seated and routing avoids sharp bends or excessive strain. Use within the specified maximum distance (30 m) for 25GBASE‑T and 40GBASE‑T performance; for longer runs, consider fiber or alternative cabling solutions.

Recommendations

For best performance, install the cable away from large power sources and noisy electrical equipment. Secure cable runs with proper management accessories to avoid kinks and maintain shielding integrity. Verify compatibility of connected devices with 25G/40G RJ45 ports before deployment.
