## Summary description

ROLINE Cat8.1 networking cable (model 21.15.3403), 3 m length, S/FTP (S-STP) shielding and RJ-45 connectors at both ends with gold-plated contacts. Supports data transfer rates up to 40,000 Mbit/s. Grey cable designed for high-speed LAN, data center links and backbone connections where shielded, high-bandwidth cabling is required.

## Long description

ROLINE 21.15.3403 is a slim, double-shielded Category 8.1 (Class I) patch cord with screened RJ-45 connectors on both ends. The cable supports data rates up to 40 Gbit/s, uses bare copper conductors and gold-plated contacts, and is halogen-free, flame-retardant and low-smoke (LSOH). With molded kink protection and an outer diameter of approximately 4.5 mm it is designed for reliable performance in high-speed Ethernet and PoE installations.
Advantages
The Cat8.1 S/FTP construction (foil‑shielded pairs with an overall braided shield) provides strong protection against electromagnetic interference while maintaining a slim profile for space-saving routing. Gold-plated contacts and stranded copper conductors ensure stable signal transmission and durability. The cable is specified for 40 Gigabit Ethernet and is compatible with Power over Ethernet, and its LSOH jacket reduces hazardous emissions in case of fire.
Suitable for
 Data center interconnects and server-to-switch links
 High-speed LAN backbones and aggregation links
 PoE-enabled devices requiring reliable power and data delivery
 Environments where low smoke and halogen-free materials are required
Key specifications
 Cable standard: Category 8.1 (Class I), S/FTP (S‑STP) — foil shielded pairs with overall braid
 Maximum data rate: 40 Gbit/s
 Connector type: RJ-45 straight male — both ends
 Conductor: 8-wire stranded cable with bare copper conductors
 Contact plating: gold-plated contacts
 PoE: supports Power over Ethernet
 Outer diameter: approximately 4.5 ± 0.2 mm
 Jacket: halogen-free, flame-retardant, low-smoke (LSOH)
 Length: 3 m
 Colour: grey
How to use
Connect one RJ-45 plug to the network device (switch, router or NIC) and the other end to the corresponding port on the remote device, ensuring secure seating of the plugs. Route the slim cable through cable management paths, avoiding sharp bends and excessive strain; molded kink protection reduces stress at the connector. For PoE deployments, verify device compatibility and power budgets before connecting.
Usage recommendations
For optimal performance, keep cable run lengths within standards for Cat8 cabling and avoid running the cable parallel to strong electrical sources. Use appropriate patch panels or shielded connectors in installations that require end-to-end shielding continuity.
