Network patch cable DIGITUS CAT 8.1 S/FTP RJ-45–RJ-45, 5 m, grey

DIGITUS CAT 8.1 S/FTP patch cable, 5 m, grey, is a high-end network connection cable engineered for short-distance, high-bandwidth Ethernet links in data centers, server rooms and professional LAN environments. Compliant with ISO/IEC 11801 and DIN EN 50173 CAT 8.1 standards and tested up to 2000 MHz, this S/FTP (S‑STP) cable uses copper inner conductors and metal-shielded RJ-45 connectors to provide improved protection against crosstalk and electromagnetic interference. The cable supports up to 40 Gbps for applicable short-reach channels and is PoE++ compatible. A molded anti-kink sleeve with strain relief and locking lever protection reduces the risk of connector damage and cable kinking during installation and use. The LSZH outer sheath minimizes smoke and harmful gases in case of fire, and the green-tinted transparent connector distinguishes Category 8.1 performance.

Advantages

The DIGITUS CAT 8.1 S/FTP cable offers a combination of very high frequency capability (tested to 2000 MHz) and robust shielding (S/FTP) that reduces near-end crosstalk and EMI, delivering stable high-speed links. Its LSZH jacket provides improved fire safety with low smoke emissions. Molded strain relief and locking lever protection extend connector durability and make repeated plug cycles and rack installations more reliable. PoE++ compatibility allows the cable to carry higher-powered Ethernet devices when needed.

Suitable for

• Short-reach 25/40 Gbps Ethernet links in data centers and server rooms
• High-density professional LAN installations requiring Cat 8.1 performance
• Connections between switches, patch panels and servers in structured cabling
• PoE++ powered devices where higher power delivery over Ethernet is required

How to use

Install the 5 m DIGITUS CAT 8.1 S/FTP patch cable by securely inserting each RJ-45 connector into the corresponding shielded port on switches, patch panels or network devices until the locking tab clicks. Route the cable avoiding tight bends and excessive tension; the molded anti-kink sleeve helps maintain the correct bend radius near the connector. For optimal channel performance, use within a structured cabling channel that meets CAT 8.1 installation guidelines and keep total channel lengths within recommended limits for 40 Gbps operation.

Usage recommendations

Use this cable for short, high-speed links in professional environments where Cat 8.1 performance, EMI protection and low-smoke materials are required. Combine with compliant shielded connectors, panels and cable management to preserve shielding continuity and achieve expected performance.
