Networking Cable EFB Elektronik K5525FGE.20 RJ-45 Cat6a 20 m Yellow

The EFB Elektronik K5525FGE.20 RJ-45 Cat6a 20 m Yellow is a high-performance network cable designed for reliable wired connections in home and office environments. Compliant with Cat6a cabling standards and featuring S/FTP shielding, this 20-metre cable supports 10GBase-T transmission and data rates up to 10000 Mbit/s while maintaining signal integrity over longer distances. Gold-plated RJ-45 contacts improve contact reliability and reduce corrosion, and the bright yellow jacket increases visibility in crowded cabling runs.

Advantages

Shielded S/FTP construction provides protection against electromagnetic interference and crosstalk, which helps sustain high transfer speeds and low error rates. Cat6a specification allows for 10 Gbps Ethernet performance at typical installation lengths. Gold-plated connectors offer stable electrical contact and resistance to oxidation. The 20 m length covers many desktop-to-switch and room-to-room connections without requiring intermediate patch panels. The yellow outer sheath improves identification and routing in multi-cable installations.

Suitable for

• 10 Gigabit Ethernet connections between switches, servers and workstations
• Structured cabling runs in small offices and home networks
• Data-intensive applications such as video streaming, backups and large file transfers
• Temporary or permanent connections in server rooms, media rooms and AV setups

Key specifications

• Transmission standard: 10GBase-T
• Maximum data rate: up to 10000 Mbit/s
• Connector type: RJ-45 to RJ-45 with gold-plated contacts
• Cable length: 20 m
• Outer colour: Yellow

How to use

Uncoil the cable carefully to avoid kinks and route it along cable management paths or through cable trays where possible. Insert the RJ-45 connectors into the corresponding Ethernet ports on network devices until they click, ensuring secure engagement. For best performance, avoid tight bends (maintain bend radius recommended by Cat6a standards), keep the cable away from strong EMI sources where possible, and use proper strain relief near connectors. When connecting to patch panels or keystones, verify polarity and test the link with a network tester to confirm gigabit or 10G connectivity.

Recommendations

Use this Cat6a S/FTP cable for critical links that require consistent 10 Gbps performance or increased immunity to interference. For permanent installations, label both ends and secure the cable with Velcro straps rather than metal ties to prevent damage. If running alongside power lines or noisy equipment, increase separation or route in separate conduits to preserve signal integrity.
