## Summary description

ROLINE Cat8.1 network cable, 0.5 m length, with S/FTP (S-STP) shielding and RJ-45 connectors on both ends. Gold-plated contacts support data transfer rates up to 40,000 Mbit/s. Compact grey cable for high-speed connections in data centers, server racks, switches or short patch runs where shielded Cat8.1 performance is required.

## Long description

ROLINE 21.15.3400 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, and is halogen-free, flame-retardant and low-smoke (LSOH). It supports Power over Ethernet (PoE) and is suitable for high-density cabling environments where space and performance are required.
Advantages
The fully shielded S/FTP construction (foil individually shielding pairs plus overall braided shield) and double-shielded RJ-45 connectors reduce electromagnetic interference and crosstalk, enabling reliable 40 Gigabit Ethernet performance. The slim design with an outer diameter of approximately 4.5 mm saves space in cable ducts and patch panels. Gold-plated contacts and molded kink protection increase contact reliability and mechanical durability, while LSOH materials minimize hazardous emissions in case of fire. Plug-and-play PoE compatibility allows easy integration into powered network devices.
Suitable for
40 Gigabit Ethernet connections in data centers and server rooms
High-speed uplinks between switches and network equipment
Environments requiring shielded cabling to reduce interference
Installations where low smoke and halogen-free materials are required

How to use
Connect each end of the ROLINE Cat8.1 patch cord to the RJ-45 ports of your network devices, switches or patch panels following the standard 1:1 contact wiring (EIA/TIA 568). Ensure connectors are fully inserted until they click to establish a secure connection. For PoE applications, verify that connected devices and power sources are PoE-compatible and observe manufacturer power ratings.
Usage recommendations
Route the slim patch cord through cable management channels and avoid tight bends near the connectors; maintain the specified bend radius to preserve performance. Use shielded patch panels and maintain proper grounding for the overall shield to maximize EMI protection. Select appropriate cable lengths for rack layouts to minimize excess slack.
