Networking Cable EFB Elektronik K8104BL.20 RJ-45 Cat6 20 m Blue

The EFB Elektronik K8104BL.20 RJ-45 Cat6 20 m Blue networking cable is designed for wired Ethernet connections at home or in the office. It conforms to the Cat6 standard and uses U/UTP construction to deliver reliable signal transmission over a 20 meter length. Both ends feature RJ-45 connectors with gold plating to support stable contact and reduced corrosion, and the cable supports data transfer rates up to 5000 Mbit/s. The blue jacket provides clear visual identification in structured cabling runs.

Advantages

This Cat6 cable offers balanced performance and compatibility with Gigabit and faster Ethernet equipment. The U/UTP design keeps the cable flexible while maintaining signal integrity for typical LAN applications. Gold-plated RJ-45 connectors improve conductivity and long-term reliability at connection points. The 20 m length reduces the need for intermediate patch panels in small to medium installations and the colored jacket simplifies cable management.

Suitable for

• Wired Ethernet connections for desktop computers and workstations
• Connecting switches, routers and patch panels within local networks
• Home networks, small office setups and media streaming
• Temporary or semi-permanent installations requiring a visible cable colour

Key specifications

• Category: Cat6
• Shielding: U/UTP (unshielded overall, unshielded pairs)
• Connector type: RJ-45 to RJ-45
• Connector plating: gold-plated contacts
• Cable length: 20 m
• Maximum practical data rate: up to 5000 Mbit/s
• Colour: blue

How to use

Route the cable from one network device to another, ensuring the RJ-45 connectors are fully inserted into the device ports until they click. Avoid tight bends and sharp kinks; maintain a bend radius at least four times the cable diameter for optimal performance. Keep the cable run separated from high-voltage power lines and strong electromagnetic sources to reduce potential interference. If used in a rack or patch panel, label both ends for easier identification and future maintenance.

Recommendations

For consistent performance, test wired links after installation using network diagnostic tools or cable testers and avoid exceeding the cable’s recommended length for the intended application. Use the blue jacket to organize and distinguish this link from other network runs.
