Networking cable EFB Elektronik K8055.25 RJ-45 Cat6a 25 m Yellow

The EFB Elektronik K8055.25 RJ-45 Cat6a networking cable is a 25 m yellow S/FTP cable designed for reliable high-speed Ethernet connections. Built to Cat6a specifications, it supports data transfer rates up to 10 000 Mbit/s and is fitted with RJ-45 connectors on both ends. The S/FTP shielding reduces electromagnetic interference, improving signal integrity across longer runs and in environments with multiple cables or electronic equipment.

Advantages

The cable’s Cat6a construction ensures consistent performance at gigabit and 10-gigabit Ethernet speeds while S/FTP shielding provides improved protection against crosstalk and external noise. Its 25 m length covers longer distances without the need for additional patching, and the yellow jacket makes routing and identification straightforward in patch panels and cable trays. Standard RJ-45 connectors ensure compatibility with a wide range of network devices.

Suitable for

• 10 Gigabit Ethernet links in offices, data centers, and server rooms
• Structured cabling between network switches, patch panels and wall outlets
• Environments with multiple cable bundles or nearby electronic equipment where interference reduction is needed

Key specifications

• Cable type: Cat6a (augmented Category 6)
• Length: 25 m
• Connectors: RJ-45 to RJ-45
• Shielding: S/FTP (overall shield with individually shielded pairs)
• Nominal maximum data rate: up to 10 000 Mbit/s
• Colour: yellow

How to use

Route the cable between devices making sure the run length does not exceed 25 m and avoid sharp bends or tension that could damage the internal conductors and shielding. Terminate each end into standard RJ-45 ports on switches, routers, network interface cards, or patch panels. When installing in high-density bundles, maintain appropriate separation from power cables where possible and use cable management accessories to secure the cable and preserve its bend radius.

Recommendations

For best performance, test the installed link with a cable certifier or network tester supporting Cat6a parameters. Avoid running alongside high-voltage power lines and keep connector contacts free of dust. Use the cable’s bright yellow colour for clear identification when documenting or labelling network runs.
