Networking cable EFB Elektronik Cat6a S/FTP (S‑STP) Red 40 m RJ-45 to RJ-45

The EFB Elektronik Cat6a S/FTP (S-STP) RJ45 patch cable, 40 m, is designed for high-speed networks including 10 Gigabit Ethernet. Manufactured in Europe using Draka Cat.7 UC900 SS27 raw cable and Hirose TM21 connectors, this red networking cable features gold-plated RJ45 contacts and full-pair shielding for stable data transmission up to 10,000 Mbit/s.

Advantages

The cable combines Cat6a standard performance with enhanced shielding (S/FTP) to reduce crosstalk and electromagnetic interference. European manufacturing and quality components—Draka cable core and Hirose connectors—ensure consistent electrical characteristics. Gold-plated contacts improve contact reliability and corrosion resistance, while the 40 m length supports longer runs without intermediate patching.

Suitable for

• 10 Gigabit Ethernet networks
• High-density wiring in data centres and server rooms
• Office LAN connections and backbone links
• Applications requiring reduced electromagnetic interference

How to use

Route the 40 m Cat6a S/FTP patch cable between network devices such as switches, servers and patch panels. Plug RJ45 connectors fully into the corresponding ports until the retention latch clicks. Avoid tight bends and kinks; maintain recommended bend radius for Cat6a cables. Ensure both ends are connected to compatible Ethernet ports rated for the intended data rate.

Recommendations

For best performance, keep the cable away from strong electromagnetic sources (large motors, fluorescent ballast, power cables). Use cable management (trays or cable ties) to prevent strain and maintain the shielding integrity; test links after installation to verify 10 Gigabit operation if required.
