## Summary description

The ROLINE 21.15.2550 is a 0.5 m black networking cable that meets Cat6 standards. It features U/UTP shielding and RJ-45 connectors on both ends, ensuring reliable data transmission and minimal interference. Ideal for connecting devices in home or office networks.

## Long description

The ROLINE 21.15.2550 Black 0.5m Cat6 U/UTP is a short patch cable designed for Ethernet connections that require Cat6 performance. With a 0.5 m length, black jacket and RJ-45 connectors on both ends, this cable supports standard Gigabit Ethernet speeds and is suitable for linking network devices where a short, reliable connection is needed. The U/UTP construction provides an unshielded twisted pair core with an overall unshielded jacket, offering predictable signal transmission and reduced crosstalk compared with older cable categories.
Advantages
The cable’s Cat6 specification ensures improved frequency handling and lower crosstalk compared to Cat5e, supporting higher data rates and more reliable connections in local networks. Its short 0.5 m length reduces excess cable clutter and signal degradation in patching scenarios. Standard RJ-45 connectors on both ends guarantee compatibility with switches, routers, NICs and patch panels. The black outer jacket offers discreet installation in visible areas and easy visual matching with other equipment.
Suitable for
Connecting a PC or laptop to a nearby switch or router
Patching between ports in a rack or patch panel
Short-distance connections in home or small office networks
Replacing or extending existing short Ethernet links
Key specifications
Cable category: Cat6
Shielding type: U/UTP (overall unshielded, twisted pairs)
Length: 0.5 m
Connectors: RJ-45 to RJ-45
Colour: Black
How to use
Insert each RJ-45 connector firmly into the corresponding Ethernet ports of the devices you want to link until the connector latch clicks. Verify the network interfaces recognize the connection and check link/activity LEDs on the devices for proper negotiation. For best performance, avoid tightly bending the cable near the connectors; maintain gentle curves to preserve pair integrity. Use the 0.5 m length for direct point-to-point links or short patching within racks and workstations.
Usage recommendations
For stable Gigabit performance, keep the cable run within its intended short-distance use and avoid running it parallel to high-voltage power lines. Inspect connectors for secure seating and replace the cable if the jacket or connector shows visible damage. When organizing multiple cables, label both ends for easier maintenance and to prevent accidental disconnection.
