Networking cable ROLINE 21.15.2555 RJ-45 Cat6 5 m Black

The ROLINE 21.15.2555 RJ-45 Cat6 5 m Black networking cable is a 5-metre Ethernet patch cable designed for Cat6 performance. It uses standard RJ-45 connectors at both ends and follows U/UTP construction to provide reliable data transfer with reduced external interference. The black jacket offers a neutral appearance suitable for visible installations in home or office environments and for organizing network setups in racks, desks, or behind equipment.

Advantages

This Cat6 cable supports higher bandwidth and improved signal integrity compared with lower-category cables, making it suitable for gigabit Ethernet and many modern network applications. The U/UTP shielding reduces crosstalk and susceptibility to external electromagnetic interference without adding bulk. Standard RJ-45 terminations ensure compatibility with switches, routers, patch panels and network interface cards. The 5 m length balances reach and manageability for typical desk-to-wall or cabinet-to-equipment connections.

Suitable for

• Connecting PCs, laptops or printers to wall outlets, switches or routers
• Patching between network switches, patch panels and rack equipment
• Home networking where a 5 m cable run is required
• Office workstations and small server or network closets

Key specifications

• Cable category: Cat6
• Length: 5 m
• Connector type: RJ-45 to RJ-45
• Shielding: U/UTP (unshielded twisted pairs with overall jacket)
• Colour: Black

How to use

Plug one RJ-45 connector into the Ethernet port of your device and the other into the port of a switch, router or wall outlet. Ensure connectors are fully inserted until the RJ-45 clip latches to provide a secure electrical and mechanical connection. Route the cable to avoid sharp bends and keep it away from sources of strong electromagnetic interference such as large transformers or heavy-duty electrical wiring. For tidy installations, use cable ties or cable management panels to secure excess length.

Usage recommendations

For best performance, avoid tightly coiling the cable and maintain bend radii larger than the cable diameter. When installing in structured cabling environments, label both ends for easier maintenance and keep runs within recommended length limits for Ethernet standards. If the environment has high electromagnetic interference, consider using shielded cabling systems end-to-end and grounding where appropriate.
