Networking cable EFB Elektronik K5525FSW.3 RJ-45 Cat6a 3 m Black

The EFB Elektronik K5525FSW.3 RJ-45 Cat6a 3 m Black is a network patch cable designed for high-speed Ethernet connections. It follows the Cat6a standard and uses S/FTP shielding to reduce electromagnetic interference and crosstalk. The cable is fitted with RJ-45 connectors and gold-plated contacts to maintain reliable signal transmission and corrosion resistance. With a 3 m length and a black jacket, it is suitable for structured cabling in offices, server rooms, and home networks that require stable Gigabit and 10 Gigabit connectivity.

Advantages

The S/FTP shielding construction combines an overall foil with individually braided shields for each twisted pair, improving noise immunity in electrically noisy environments. Gold-plated RJ-45 contacts provide consistent contact quality and minimize oxidation over time. Cat6a specification supports higher frequencies and provides headroom for 10 Gbit/s Ethernet at shorter distances, while the 3 m length offers flexibility for desktop and rack connections without excess cable slack.

Suitable for

• 10 Gigabit Ethernet links in data centers and network closets
• Gigabit connections for office workstations and switches
• Connecting routers, switches, patch panels and network appliances
• Home network setups where reduced interference and tidy cabling are required

Key specifications

• Category: Cat6a
• Shielding: S/FTP (overall foil with individually shielded pairs)
• Connectors: RJ-45 to RJ-45 with gold-plated contacts
• Maximum supported data rate: up to 10000 Mbit/s (10 Gbit/s)
• Length: 3 m
• Colour: Black

How to use

Plug each RJ-45 connector into the corresponding network ports on your devices, such as switches, routers, patch panels or network interface cards. Ensure connectors click into place to confirm a secure mechanical connection. Route the cable to avoid sharp bends and sources of strong electromagnetic interference; maintain bend radii appropriate for Ethernet cables to preserve performance. For best results in rack or structured environments, use cable management accessories to keep runs neat and reduce strain on connectors.

Usage recommendations

For sustained 10 Gbit/s performance, keep cable runs within recommended distances for Cat6a and avoid bundling large numbers of cables with power lines. Inspect connector ends for dirt before insertion and avoid repeated flexing at the connector strain relief to extend cable life.
