## Summary description

ROLINE Cat8.1 network cable, model 21.15.3450, 0.5 m length with S/FTP (S-STP) shielding and gold-plated RJ-45 contacts. Supports up to 40,000 Mbit/s data transfer rate. Compact patch cable for high-speed connections between switches, servers or patch panels in data centers, offices and high-performance home networks.

## Long description

ROLINE 21.15.3450 is a slim, double-shielded Category 8.1 (Class I) patch cord with screened RJ-45 connectors on both ends, designed for data rates up to 40 Gbit/s. The cable uses bare copper conductors, gold-plated contacts and a compact outer diameter for space-saving installation. Its halogen-free, flame-retardant and low-smoke (LSOH) construction makes it suitable for environments with strict safety requirements, and it supports Power over Ethernet (PoE).
Advantages
The double-shielded S/FTP (S-STP) design provides effective protection against electromagnetic interference while maintaining high transmission performance required for 40 Gigabit Ethernet. The slim 4.5 ± 0.2 mm outer diameter enables tidy routing in dense patching environments. Molded kink protection increases connector durability and gold-plated contacts ensure reliable signal transmission. LSOH jacket enhances safety in case of fire and the cable is ready for PoE applications.
Suitable for
Server rooms and data centre patching where 40 Gigabit links are required
High-speed network connections between switches and routers
Environments with limited cable space or dense cable management
Installations requiring halogen-free, low-smoke cabling for safety
Key specifications
Cable standard: Category 8.1 (Class I)
Shielding: S/FTP (overall braid with foil-shielded pairs)
Connectors: RJ-45 to RJ-45, straight male
Conductor: 8-wire stranded, bare copper
Contact plating: gold-plated contacts
Data rate: up to 40 Gbit/s (40000 Mbit/s)
PoE: supports Power over Ethernet (plug and play)
Outer diameter: approx. 4.5 ± 0.2 mm
Colour: black
Length: 0.5 m
How to use
Connect one RJ-45 connector to the network device and the other to the corresponding port on a switch, router or patch panel, ensuring the 1:1 contact assignment compatible with EIA/TIA 568 wiring. The slim cable allows straightforward routing through cable ducts and patch cabinets; avoid excessive bending at the molded kink protection to maintain performance. No special tools are required for typical plug-and-play PoE operation.
Usage recommendations
For optimal performance at 40 Gbit/s, keep cable runs within recommended distances for copper Category 8.1 and avoid sharp bends or mechanical stress. Use in compliance with site safety standards for halogen-free cabling and ensure connectors are fully seated to maintain reliable contacts.
