Networking cable ROLINE 21.15.2520 RJ-45 Cat6 0.5 m Yellow

The ROLINE 21.15.2520 RJ-45 Cat6 0.5 m Yellow networking cable is a short patch cable designed for reliable Ethernet connections in environments where space is limited or where a visible cable color is required. It conforms to the Cat6 specification and uses RJ-45 connectors on both ends, offering support for typical gigabit network speeds over short distances. The cable features U/UTP construction to reduce external interference and is finished in yellow for easy identification in cabling bundles and patch panels.

Advantages

This Cat6 patch cable provides a compact, easy-to-install solution for linking network devices where a half-meter length is sufficient. The U/UTP shielding helps minimize crosstalk and electromagnetic interference from nearby cables and equipment. RJ-45 connectors on both ends ensure compatibility with standard Ethernet ports, while the yellow jacket improves visibility for maintenance and cable management. The cable’s short length reduces clutter and signal degradation associated with longer runs in patch environments.

Suitable for

• Patching between network switches and wall outlets in server rooms and communication cabinets
• Connecting network devices in cramped workstations or behind AV equipment
• Identifying and separating specific connections using color-coded cabling
• Temporary setups or test benches where short, reliable links are required

Key specifications

• Category: Cat6
• Length: 0.5 m
• Connector type: RJ-45 to RJ-45
• Shielding: U/UTP (unshielded twisted pair with overall braid absent, pair-level or overall interference reduction design)
• Color: Yellow

How to use

Insert each RJ-45 connector into the Ethernet ports of the devices you wish to connect, ensuring a firm click indicates a secure connection. Use the cable for short-distance links between patch panels, switches, routers, network interface cards or wall sockets. Route the cable to avoid tight bends and strain on the connectors; maintain gentle curves and secure the cable with cable ties or management clips if needed. For best performance, avoid running the cable parallel to high-voltage power lines and sources of strong electromagnetic interference.

Usage recommendations

For reliable gigabit performance, use this half-meter Cat6 cable for short patch connections within racks or between nearby devices. Keep connector contacts clean and avoid excessive bending or tension. Use color-coded cables like the yellow jacket to simplify identification and reduce downtime during maintenance.
