Networking cable ROLINE 21.15.3953 RJ-45 Cat6a 1 m Black

The ROLINE 21.15.3953 RJ-45 Cat6a 1 m Black is a 1-metre network patch cable designed for reliable wired Ethernet connections. Constructed to the Cat6a standard with U/UTP topology, this cable supports high-speed data transmission and reduces susceptibility to external electromagnetic interference. The cable features RJ-45 connectors on both ends and a black jacket that fits professional and home network environments.

Advantages

This Cat6a cable provides enhanced bandwidth and improved alien crosstalk performance compared with lower-category cables, making it suitable for 10 Gigabit Ethernet over shorter runs. The U/UTP construction offers a balance between flexibility and basic shielding performance, while the RJ-45 terminations ensure compatibility with standard network equipment. The 1 m length helps maintain tidy installations and reduces excess cable in racks, desktops, and patch panels.

Suitable for

• Connecting switches, routers and patch panels in small offices
• Linking desktop PCs, workstations and network printers
• Short 10 Gigabit Ethernet links in structured cabling
• Home network setups where a short, reliable patch cable is required

Key specifications

• Category: Cat6a
• Length: 1 m
• Connector type: RJ-45 to RJ-45
• Shielding: U/UTP (unshielded twisted pair with overall unshielded)
• Colour: Black
• Typical use: Patch cable for Ethernet networks

How to use

Route the cable between the two network devices you wish to connect, avoiding sharp bends and sources of strong electromagnetic interference where possible. Insert each RJ-45 connector fully into the device ports until the latch clicks. For structured cabling, use the cable for short patch connections within racks, wall plates or switch ports. Verify link activity and speed using the devices' network status indicators or network testing tools.

Recommendations

For optimal performance, keep the cable length short and avoid running it parallel to power lines. Use it for internal patching rather than long-distance backbone runs. Test connections after installation to confirm expected link speeds and consider using Cat6a-rated patch panels and keystone jacks for consistent performance.
