Networking Cable EFB Elektronik K8580BL.25 RJ-45 Cat6a 25 m Blue

The EFB Elektronik K8580BL.25 RJ-45 Cat6a 25 m Blue is a shielded Ethernet cable designed for high-speed wired networks. This Cat6a cable supports data transfer rates up to 10000 Mbit/s and is fitted with RJ-45 connectors on both ends. The S/FTP shielding reduces electromagnetic interference and crosstalk, while gold-plated contacts improve contact reliability and corrosion resistance. The 25 m length provides flexibility for connecting devices across rooms or within server cabinets, and the blue jacket allows easy visual identification in structured cabling installations.

Advantages

The S/FTP construction combines an overall foil shield with individually shielded pairs to minimize external noise and internal pair-to-pair interference. Cat6a specification ensures stable performance at higher frequencies and supports 10 Gigabit Ethernet over the full 25 m length. Gold-plated RJ-45 contacts offer improved conductivity and a lower risk of connection faults over time. The cable’s flexible jacket and consistent impedance make it suitable for permanent installations and temporary setups where reliable throughput is required.

Suitable for

• 10 Gigabit Ethernet connections in offices and data centers
• Patch cabling between switches, routers and network devices
• High-bandwidth applications such as video streaming, virtualization and large file transfers
• Structured cabling where color-coded cables help organization

Key specifications

• Standard: Cat6a
• Connector type: RJ-45 to RJ-45
• Cable shielding: S/FTP (overall foil + individually shielded pairs)
• Maximum data rate: up to 10000 Mbit/s
• Length: 25 m
• Contact plating: gold-plated contacts
• Colour: blue

How to use

Route the cable between network devices, avoiding sharp bends and tight coils to maintain impedance and shielding effectiveness. Insert the RJ-45 connectors firmly into the compatible ports on switches, routers or network interface cards until the latch clicks. For permanent installations, secure the cable with appropriate clips or cable management accessories and maintain separation from power lines to reduce interference. Test the connection with a network tester or by verifying link speed on connected equipment.

Usage recommendations

For optimal performance, keep cable runs within recommended lengths for Cat6a environments and avoid running parallel to high-current power cables. Use proper cable management to prevent physical stress, and verify termination and link speeds after installation to ensure 10 Gigabit operation where required.
