Sieťový kábel EFB Elektronik K8580SW.20 RJ-45 Cat6a 20 m čierny

The EFB Elektronik K8580SW.20 RJ-45 Cat6a 20 m Black networking cable is designed for high-speed wired connections in professional and home environments. Compliant with Cat6a standard and using S/FTP shielding, this 20-meter cable supports data transfer rates up to 10000 Mbit/s and provides reliable transmission for bandwidth-intensive applications. Gold-plated RJ-45 connectors are fitted at both ends for stable contact and reduced signal loss, while the black outer sheath offers a discreet appearance for rack, office or residential installations.

Advantages

S/FTP shielding around the conductors reduces electromagnetic interference and crosstalk, improving signal integrity over longer runs. The Cat6a specification ensures support for 10 Gigabit Ethernet and greater bandwidth headroom compared with lower category cables. Gold-plated RJ-45 connectors enhance durability and provide consistent contact resistance for sustained performance. The 20 m length provides flexibility for equipment placement without the need for additional patching or intermediate switches.

Suitable for

• 10 Gigabit Ethernet connections in server rooms and data centers
• High-bandwidth LAN connections for office workstations and meeting rooms
• Home networking for streaming, gaming and media servers
• Structured cabling runs between network switches and patch panels

Key specifications

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

How to use

Connect one RJ-45 plug to the network port of your device (switch, router, network card) and the other plug to the corresponding port on the remote device. Ensure connectors are fully inserted until the latch clicks to secure the connection. Route the cable to avoid tight bends, sharp edges and sources of strong electromagnetic interference. For best performance, avoid running the cable parallel and close to power lines or large electrical equipment.

Recommendations

Use the cable for direct Ethernet links up to 20 m without intermediate patch panels when maintaining 10 Gbps speeds. For permanent installation in walls or ceilings, verify local building codes and consider using plenum-rated alternatives if required. Periodically inspect connectors for corrosion or damage and replace if contact quality deteriorates.
