## Summary description

ROLINE Cat8.1 networking cable, model 21.15.3440, 0.5 m length in blue. S/FTP (S-STP) shielding with gold-plated RJ-45 connectors on both ends supports up to 40,000 Mbit/s. Designed for high-speed Ethernet links, server racks, switches and short patch connections where low interference and secure data transfer are required.

## Long description

High-quality slim Category 8.1 (Class I) patch cord with double shielding and screened RJ-45 connectors on both ends, designed for data rates up to 40 Gbit/s. The cable features bare copper conductors, gold-plated contacts and a compact 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
Double shielding (foil around each pair and an overall braid) ensures improved protection against electromagnetic interference. Slim construction and molded kink protection provide easy routing in dense patch panels and reduced risk of cable damage. Gold-plated contacts promote reliable connections, while LSOH materials increase safety in confined or public spaces. The cable supports 40 Gigabit Ethernet and plug-and-play PoE applications.
Suitable for
Server rooms and data center uplinks requiring 40 Gbit/s connections
High-speed workstation-to-switch links in enterprise networks
Environments where low smoke and halogen-free materials are required
PoE-powered devices that need high-bandwidth cabling

How to use
Connect one RJ-45 end to a network device or switch port and the other end to the corresponding port on the target device. Ensure connectors are fully inserted until the latch clicks. Use the cable for short high-speed links such as between switches, patch panels and servers; avoid excessive bending beyond the manufacturer's recommended bend radius to maintain signal integrity.
Usage recommendations
For optimal performance, keep the cable length appropriate for the link (this 0.5 m patch cord is intended for short, high-density connections), avoid tight bends and secure with cable management hardware. Verify PoE power requirements of connected devices and ensure switch ports support the required power class.
