Networking Cable EFB Elektronik K5547SW.0,5 RJ-45 Cat6a 0.5m Black

The EFB Elektronik K5547SW.0,5 is a Cat6a networking cable with a 0.5 m length and RJ-45 connectors on both ends. Designed for 10GBase-T applications, it supports data transfer rates up to 10000 Mbit/s. The cable uses U/FTP (STP) shielding to reduce electromagnetic interference and features gold-plated contacts for reliable signal transmission and improved durability. Its black jacket offers a discrete appearance suitable for professional and home network setups.

Advantages

This Cat6a cable provides high bandwidth suitable for 10GBase-T networks while maintaining a compact 0.5 m form factor for tidy connections in patch panels, switches and desktop equipment. The U/FTP (STP) shielding limits crosstalk and external interference, which helps preserve signal integrity in dense cabling environments. Gold-plated RJ-45 contacts ensure consistent contact quality and resistance to corrosion, supporting long-term performance.

Suitable for

• Connecting network switches, routers and patch panels at short distances
• Linking desktop PCs or servers to nearby network ports
• 10GBase-T segments and high-bandwidth workstation links
• Environments requiring shielded cabling to reduce interference

Key specifications

• Category: Cat6a (supports 10GBase-T)
• Length: 0.5 m
• Connectors: RJ-45 to RJ-45
• Shielding: U/FTP (screened foiled twisted pair)
• Contacts: Gold-plated
• Colour: Black
• Maximum data rate: up to 10000 Mbit/s

How to use

Plug each RJ-45 connector into the corresponding network port on your devices, ensuring the connectors click into place. Use the 0.5 m length for short runs between adjacent equipment such as switch-to-switch ports, switch-to-server, or workstation patch connections. For shielded performance, verify that connected ports or patch panels are grounded appropriately to take full advantage of the U/FTP shielding. Avoid sharp bends and excessive tension in the cable to maintain signal performance.

Recommendations

Choose this short Cat6a cable when you need reliable, shielded 10GBase-T links in confined spaces. For longer runs or in installations without proper grounding, consider alternative cable lengths or check grounding of shielded connectors to ensure optimal interference protection.
