## Summary description

ROLINE 21.15.3451 is a 1 m Cat8.1 network patch cable with S/FTP (S‑STP) shielding and gold‑plated RJ-45 connectors. It supports data transfer rates up to 40,000 Mbit/s and is designed for high‑speed Ethernet and data centre connections. The black cable is suitable for short runs, server racks, switches and workstation links where EMI protection and high bandwidth are required.

## Long description

ROLINE 21.15.3451 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 stranded 8-wire construction with foil‑shielded pairs and an overall braided shield. The outer jacket is halogen-free, flame-retardant and low-smoke (LSOH), and the cable supports Power over Ethernet (PoE).
Advantages
The cable provides high transmission performance for 40 Gigabit Ethernet while maintaining a slim profile thanks to its 4.5 ± 0.2 mm outer diameter. Double shielding (S/FTP) and gold-plated contacts reduce interference and ensure reliable connectivity. Molded kink protection increases durability, and the halogen-free, flame-retardant low-smoke jacket improves safety in confined installations. Connectors are wired 1:1 per EIA/TIA 568 standard for straightforward plug-and-play use.
Suitable for
 High-speed server and switch connections in data centers
 Short-distance 40 Gigabit Ethernet links
 PoE-powered devices where high bandwidth is required
 Environments requiring low-smoke, halogen-free cabling
Key specifications
 Standard: Category 8.1 (Class I)
 Shielding: S/FTP (overall braid with foil‑shielded pairs)
 Connectors: RJ-45 male to RJ-45 male, straight
 Conductor: Bare copper, stranded 8-wire
 Contact plating: Gold
 Maximum data rate: 40 Gbit/s (40000 Mbit/s)
 Outer diameter: approx. 4.5 ± 0.2 mm
 Length: 1 m
 Color: Black
How to use
Connect one RJ-45 plug to the network port of a compatible switch, router or server and the other plug to the corresponding device port. The cable uses a 1:1 contact assignment according to EIA/TIA 568, enabling immediate use without special configuration. Use the cable for short interconnects in rack or patch panel environments and avoid excessive bending beyond the molded kink protection radius to maintain performance.
Usage recommendations
For optimal performance, keep cable runs for 40 Gbit/s links within recommended short-reach distances for copper Cat8.1 installations, maintain proper grounding for shield termination, and avoid tightly coiling the cable or routing it near strong electromagnetic sources.
