Networking cable EFB Elektronik K5546SW.5 RJ-45 Cat6a 5 m Black

The EFB Elektronik K5546SW.5 is a shielded RJ45 patch cable extension Cat.6A designed for data transmissions up to 10 Gbit/s according to ISO11801. With a length of 5 m and black S/FTP jacket, this networking cable extends an existing RJ45 connection without needing to replace permanently installed cabling. It is compatible with any device that has an RJ45 port, including computers, notebooks, DSL modems, routers, switches, game consoles and televisions.

Advantages

This Cat6A extension provides S/FTP shielding that reduces electromagnetic interference and supports stable high-speed transfers up to 10 Gbit/s. Gold-plated RJ45 connectors ensure reliable contact and corrosion resistance. Using an extension cable avoids costly reinstallation of fixed cabling and can protect device sockets from wear by acting as a sacrificial connection point in frequently connected devices such as laptops.

Suitable for

• Extending an existing Ethernet connection without replacing installed cabling
• Home office setups where devices are frequently connected and disconnected
• Connecting computers, routers, switches, consoles and smart TVs
• Environments requiring reduced electromagnetic interference

Key specifications

• Standard: Cat.6A (ISO11801, supports up to 10 Gbit/s)
• Length: 5 m
• Shielding: S/FTP (overall foil + individually foil‑shielded pairs)
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Colour: Black

How to use

Connect one RJ45 plug of the extension to the existing wall or patch panel cable and the other plug to the end device’s RJ45 port. Ensure connectors are fully inserted until they click. Route the cable to avoid sharp bends and sources of strong interference. For best performance, keep cable runs within recommended lengths and avoid tight coils or kinks.

Recommendations

For stable 10 Gbit/s performance, use the cable in a compatible Cat6A environment and minimize nearby sources of electromagnetic interference. When used as a protective intermediary for laptop sockets, inspect the extension’s connectors periodically for wear and replace the extension if contact becomes unreliable.
