networking cable ROLINE 21.15.2749 Blue 20 m Cat6a U/UTP

The ROLINE 21.15.2749 is a 20 m networking cable in blue, built to Cat6a U/UTP specifications for reliable high-speed data transmission. It is intended for connecting network equipment such as routers, switches and computers in home or office environments and provides shield-free paired conductors to support gigabit and higher-speed Ethernet links.

Advantages

This Cat6a U/UTP cable offers a standardized 20 m length and RJ-45 connectors on both ends for easy plug-and-play installation. The U/UTP construction reduces external interference in typical LAN setups, while the Cat6a rating supports higher bandwidth and improved performance compared with lower-category cables. The blue jacket helps with cable identification in structured cabling.

Suitable for

• Connecting routers, switches and desktop computers
• Patch panel to switch links in offices and data closets
• Home network high-speed Ethernet connections
• Temporary or permanent horizontal LAN cabling runs up to 20 m

Key specifications

• Length: 20 m
• Cable standard: Cat6a
• Cable shielding: U/UTP (unshielded twisted pair)
• Connectors: RJ-45 to RJ-45
• Colour: Blue
• Manufacturer: ROLINE, MPN: 21.15.2749, EAN: 7611990138838

How to use

Plug each RJ-45 connector into the corresponding network ports of your devices (for example, router to switch or switch to PC). Ensure connectors are fully inserted until the latch clicks. Route the cable to avoid sharp bends and sources of strong electromagnetic interference. Test the connection after installation using network diagnostic tools or the device link/activity indicators.

Recommendations

For optimal performance, use this Cat6a U/UTP cable for links up to 20 m in standard Ethernet environments; avoid running parallel to high-voltage power lines and keep bend radius consistent with manufacturer guidance to prevent signal degradation.
