Cavo di rete EFB Elektronik K5525FSW.20 RJ-45 Cat6a 20 m nero

The EFB Elektronik K5525FSW.20 RJ-45 Cat6a 20 m Black is a 20-meter network cable designed for high-speed wired connections in professional and home environments. With S/FTP shielding and Cat6a classification, the cable supports data rates up to 10,000 Mbit/s and is suited for demanding Ethernet applications where stable throughput and reduced electromagnetic interference are required. The black jacket provides a neutral appearance that integrates easily into office racks and AV installations.

Advantages

S/FTP shielding around the conductor pairs provides improved protection against crosstalk and external electromagnetic interference, helping to maintain signal integrity over the 20 m run. Gold-plated RJ-45 connectors offer reliable contact corrosion resistance and consistent connectivity. The Cat6a specification supports higher bandwidth and better performance for 10 Gigabit Ethernet over copper. The cable’s flexible yet durable outer sheath simplifies routing and installation while preserving mechanical robustness.

Suitable for

• 10 Gigabit Ethernet connections in small offices and data closets
• High-bandwidth wired links for servers, switches, and NAS devices
• Structured cabling runs where interference resistance is important
• AV and media installations requiring long, reliable network runs

Key specifications

• Cable type: Cat6a, S/FTP (shielded foiled twisted pair)
• Length: 20 m
• Connectors: RJ-45 on both ends with gold-plated contacts
• Maximum data rate: up to 10000 Mbit/s (10 Gbit/s)
• Colour: Black

How to use

Route the cable between network devices ensuring bends do not exceed the manufacturer’s recommended radius to avoid degrading performance. Insert the RJ-45 connector firmly into the Ethernet ports of switches, routers, or network interface cards until the latch clicks. For optimal results keep the cable separated from high-voltage power lines and sources of strong electromagnetic interference. Terminate and secure the cable at patch panels or wall outlets as required for structured installations.

Recommendations

For sustained 10 Gbit/s performance, avoid excessive bundling with multiple cables over long distances and maintain adequate separation from power cabling. Inspect connectors for dust or damage before use and replace the cable if mechanical damage to the sheath or connectors is present.
