Networking cable ROLINE 21.15.3945 RJ-45 Cat6a 2 m Blue

The ROLINE 21.15.3945 RJ-45 Cat6a 2 m Blue networking cable is a shielded U/UTP Ethernet lead designed for high-speed wired connections. It follows the Cat6a specification and is fitted with RJ-45 connectors on both ends, offering a reliable physical link between network devices. The 2 m length and blue jacket make it suitable for desk-to-switch connections, patch panels or short links within server racks and office environments.

Advantages

This Cat6a cable provides enhanced bandwidth and reduced crosstalk compared with lower-category cables thanks to its support for higher frequencies and U/UTP shielding. The RJ-45 connectors ensure compatibility with standard network ports, and the 2 m length balances reach and cable management in compact setups. The blue PVC jacket makes the cable easy to identify in mixed-cable installations and helps maintain an organized network layout.

Suitable for

• Connecting PCs, switches and routers over short to medium distances
• Patch panel to switch connections in office or data cabinet
• Workstation cabling where Cat6a performance is required
• Environments requiring reduced electromagnetic interference

Key specifications

• Category: Cat6a
• Shielding: U/UTP
• Connectors: RJ-45 to RJ-45
• Length: 2 m
• Outer colour: Blue

How to use

Insert the RJ-45 connectors into the corresponding Ethernet ports on your devices until they click. Route the 2 m cable to avoid sharp bends and excessive tension; maintain gentle curves and secure the cable with cable ties or clips if needed. Ensure both ends are fully seated to establish a stable link; check link/activity LEDs on connected devices to confirm connectivity.

Recommendations

For optimal performance, avoid running the cable parallel to power lines or near sources of strong electromagnetic noise. Use this Cat6a cable for Gigabit and 10 Gigabit Ethernet links over short distances and replace if connectors show visible damage or if signal errors persist.
