Networking cable ROLINE 21.15.3952 RJ-45 Cat6a 0.5 m Black

The ROLINE 21.15.3952 RJ-45 Cat6a 0.5 m networking cable is a short patch cable designed for high-speed Ethernet connections where space is limited. Built to Cat6a specifications with U/UTP shielding and standard RJ-45 connectors on both ends, this black 0.5 m cable supports reliable data transmission for modern network equipment and eliminates excess cable length in dense rack or desktop setups.

Advantages

This Cat6a U/UTP cable delivers improved performance compared with lower-category patch cords, offering higher bandwidth capacity and better alien crosstalk control for demanding network environments. The compact 0.5 m length reduces cable clutter and signal loss associated with longer runs while RJ-45 terminations ensure compatibility with switches, routers, patch panels and network interface cards. The black jacket provides a neutral appearance suitable for visible installations.

Suitable for

• Connecting switch ports to patch panels in data cabinets
• Linking network devices on crowded desktops or behind equipment racks
• Short uplinks between network appliances and servers
• Temporary test setups and lab environments

Key specifications

• Cable type: Cat6a, U/UTP (unshielded twisted pair with overall shielding scheme)
• Connectors: RJ-45 to RJ-45
• Length: 0.5 m
• Colour: Black
• Application: Ethernet networking up to Cat6a performance levels

How to use

Insert each RJ-45 connector firmly into the corresponding port until the latch clicks to secure the connection. Use the 0.5 m cable to create short links between adjacent ports on switches, patch panels, routers or servers. Avoid sharp bends and excessive pulling force on the cable or connectors to maintain performance. When routing inside racks, keep the cable away from sources of strong electromagnetic interference when possible.

Recommendations

For optimal results, use this short Cat6a cable for interconnections where distance is minimal and high bandwidth is required. Maintain bend radii recommended for twisted-pair cables and inspect connectors for secure seating. Replace the cable if the jacket or connector shows visible damage.
