networking cable ROLINE 21.15.2759 Black 20 m Cat6a U/UTP

The ROLINE 21.15.2759 is a 20 m Cat6a U/UTP networking cable in black, designed for reliable high-speed wired connections. It uses standard RJ-45 connectors on both ends and supports modern Ethernet applications, providing a stable link between routers, switches, computers and other network devices.

Advantages

The cable's Cat6a specification enables higher bandwidth and improved performance compared with lower-category cables, while the U/UTP (UTP) construction reduces external interference for consistent data transfer. A 20 m length offers flexibility for office and home installations, and the black outer jacket provides a discreet look for visible cable runs.

Suitable for

• Wired Ethernet connections in home networks
• Office network cabling between switches, patch panels and workstations
• Connecting gaming consoles, smart TVs and streaming devices
• Temporary or permanent LAN setups requiring a 20 m reach

How to use

Plug one RJ-45 connector into the Ethernet port of your router, switch or modem and the other connector into the Ethernet port of the target device (PC, console, smart TV, etc.). Ensure connectors are fully inserted until the latch clicks. Route the cable to avoid sharp bends and stress points; secure with cable clips or ties if needed. For best performance, avoid running the cable in parallel with mains power lines.

Recommendations

Use the cable within its specified length and environment; avoid excessive twisting or crushing. For permanent installations, test link speed and signal quality after installation to confirm expected Cat6a performance.
