Cavo di rete ROLINE 21.15.3951 nero 0,3 m Cat6a U/UTP

The ROLINE 21.15.3951 Black 0.3 m Cat6a U/UTP networking cable is a short patch cable engineered for high-speed data transmission in local area networks. It complies with Cat6a performance expectations and uses U/UTP construction with RJ-45 connectors on both ends. The 0.3 m length and black jacket make it suitable for close connections between switches, patch panels and networked devices where space is limited and a discreet appearance is preferred.

Advantages

This Cat6a U/UTP cable provides enhanced bandwidth and reduced crosstalk compared with lower-category cables, supporting faster data rates and more reliable connections. The RJ-45 terminated ends ensure compatibility with standard Ethernet ports without additional adapters. Its short 0.3 m length reduces cable clutter and helps maintain tidy, organized rack or desktop setups. The black outer jacket offers a neutral aesthetic that blends into most professional environments.

Suitable for

• Patching between switch ports and patch panels in rack cabinets
• Connecting nearby devices such as PCs, IP phones or network printers
• Short runs in office desks, server rooms or home networking installations

Key specifications

• Category: Cat6a
• Shielding: U/UTP (unshielded overall, unshielded pairs)
• Connectors: RJ-45 to RJ-45
• Length: 0.3 m
• Colour: Black

How to use

Insert each RJ-45 connector firmly into the Ethernet ports of the devices you wish to connect until a click is felt. Use the cable for short connections where 0.3 m provides adequate reach; avoid stretching the cable beyond its length. Ensure connectors are fully seated and devices are powered on; the network interface will negotiate speed and duplex according to the connected equipment and network configuration.

Recommendations

For best performance, avoid tightly coiling the cable or routing it parallel to strong electrical sources. Use this short Cat6a cable for clean patching in racks or desktop arrangements; if you need longer runs or additional protection against external interference, consider a shielded or longer cable that matches the installation environment.
