## Summary description

ROLINE Cat8.1 network cable, 0.3 m length, with S/FTP (S-STP) shielding and RJ-45 connectors on both ends. Gold-plated contacts ensure reliable signal transmission and support data rates up to 40,000 Mbit/s. Compact grey patch cable for short interconnections between switches, routers, servers or patch panels in data centers and office networks.

## Long description

High-quality slim Cat 8.1 S/FTP (S-STP) patch cord with screened RJ-45 connectors on both ends. The ROLINE 21.15.3406 delivers up to 40 Gbit/s data rates over a stranded 8-wire construction with foil-shielded pairs and overall braid shielding. The cable uses bare copper conductors, gold-plated contacts and a small outer diameter (approx. 4.5 ± 0.2 mm). It is halogen-free, flame-retardant and low-smoke (LSOH) and supports Power over Ethernet (PoE).
Advantages
The double-shielded S/FTP design provides reliable protection against electromagnetic interference for high-speed 40 Gigabit Ethernet links. Slim 4.5 mm diameter and molded kink protection improve routing in dense cabling environments. Gold-plated contacts ensure stable connections and corrosion resistance, while LSOH materials reduce hazardous emissions in the event of fire. The cable is ready for PoE applications and conforms to standard RJ-45 1:1 contact wiring.
Suitable for
 High-speed 40 Gigabit Ethernet connections
 Server rooms and data centers with dense cabling
 PoE devices and installations
 Short patching runs between switches, routers and patch panels

How to use
Connect each screened RJ-45 plug to the corresponding RJ-45 ports on networking devices such as switches, routers or patch panels. Ensure connectors are fully inserted until the latch clicks. For best performance keep cable runs within recommended length limits for patch cords in Cat 8.1 installations and avoid sharp bends; the molded kink protection helps prevent damage at the connector. The cable is plug-and-play for standard Ethernet and PoE applications.
Usage recommendations
Use this slim Cat 8.1 patch cord for short, high-speed connections in server rooms or dense cable management scenarios. Avoid prolonged exposure to excessive mechanical stress and maintain separation from strong electrical noise sources where possible to preserve shielding effectiveness.
