## Summary description

ROLINE Cat8.1 network cable (model 21.15.3443) is a 3 m blue RJ-45 to RJ-45 patch cable with S/FTP (S‑STP) shielding and gold‑plated contacts. It supports up to 40,000 Mbit/s data rates and is suited for high‑speed LAN connections, data centers and server racks where robust shielding and low interference are required.

## Long description

ROLINE 21.15.3443 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 gigabits per second, this 3 m blue cable uses bare copper conductors, gold-plated contacts and an 8-wire stranded construction with foil‑shielded pairs and an overall braid. The cable is halogen-free, flame-retardant and low-smoke (LSOH) and supports Power over Ethernet (PoE).
Advantages
The double shielding and high-quality materials ensure stable high-speed transmission and improved protection against electromagnetic interference. A small outer diameter makes the cable slim and easier to route in dense installations, while molded kink protection increases connector durability. Compatible with standard 1:1 contact wiring according to EIA/TIA 568 so it fits typical RJ-45 terminations.
Suitable for
40 Gigabit Ethernet connections in data centers and server rooms
High-speed backbone links between switches or patch panels
Environments requiring PoE delivery to devices such as cameras or access points
Installations where low-smoke, halogen-free cables are required

How to use
Connect the RJ-45 straight male plugs to corresponding RJ-45 ports on switches, routers, patch panels or devices. Ensure connectors are fully inserted until they click to guarantee correct 1:1 contact alignment. Route the slim cable through cable management channels or trays, avoiding sharp bends and excessive pulling force to maintain integrity of shielding and conductors.
Usage recommendations
For optimal performance, keep cable runs within recommended lengths for Cat8.1 patching in the intended environment and avoid tight bend radii; use proper cable management and keep the cable away from strong electromagnetic sources. The cable is suitable for PoE but verify device power requirements and switch capabilities before connecting high-power PoE devices.
