Networking cable EFB Elektronik K8050.20 RJ-45 Cat6a 20 m Black

The EFB Elektronik K8050.20 RJ-45 Cat6a networking cable in black is a 20 m Ethernet cable designed for high-speed wired connections. Compliant with Cat6a performance, it supports data transfer rates up to 10000 Mbit/s and uses S/FTP (S-STP) shielding to reduce electromagnetic interference and crosstalk. Gold-plated RJ-45 connectors ensure reliable contact and stable signal transmission across the cable length, making it suitable for demanding network environments.

Advantages

This Cat6a cable provides enhanced bandwidth and improved noise immunity compared with lower-category cables, thanks to its S/FTP (S-STP) shielding. The gold-plated RJ-45 connectors minimize contact resistance and corrosion risk, ensuring consistent throughput over time. With a 20 m length and a black outer jacket, the cable offers both practical reach and a discreet aesthetic for office or home installations.

Suitable for

• Wired LAN connections in offices and homes
• High-speed data transfer between switches, routers, and servers
• Streaming 4K/8K media and online gaming with reduced latency
• Structured cabling runs where Cat6a performance is required

Key specifications

• Category: Cat6a (augmented Category 6)
• Length: 20 m
• Connector type: RJ-45 to RJ-45
• Shielding: S/FTP (S-STP) — overall braid with individually shielded pairs
• Maximum supported data rate: up to 10000 Mbit/s
• Outer colour: Black
• Connector plating: Gold-plated contacts

How to use

Connect one RJ-45 connector to your network device (router, switch, or modem) and the other to the target device (PC, NAS, or server). Ensure connectors are fully inserted until the latch clicks to secure the connection. Route the cable away from strong electrical sources or unshielded power lines to maintain shielding effectiveness. For wall or ceiling installations, use appropriate cable clips or conduit to prevent sharp bends and reduce mechanical stress.

Recommendations

For optimal performance, avoid tight bends with a radius smaller than the cable diameter, maintain separation from high-power electrical cables, and verify both connected devices support the desired network speeds. Replace or test connectors if you observe intermittent connectivity or reduced throughput.
