Networking cable EFB Elektronik K8048PUI40 — Cat6a S/FTP (S‑STP), RJ-45 to RJ-45, 40 m, black/red

The EFB Elektronik K8048PUI40 is a 40 m Cat6a S/FTP (S-STP) RJ45 patch cable designed for 10 Gigabit Ethernet connections. Manufactured using Draka UC900 SS27 Cat.7 PUR raw cable and Hirose TM21 connectors, the cable combines Cat6a performance with high-quality components and a robust outer sheath resistant to abrasion, mineral oil and ASTM oil.

Advantages

The cable supports data transfer rates up to 10,000 Mbit/s and meets Cat6a shielding requirements with S/FTP (S-STP) construction for reduced crosstalk. Gold-plated RJ45 contacts improve signal reliability and corrosion resistance. The PUR jacket increases mechanical durability and provides resistance to mineral and ASTM oils, extending service life in industrial or harsh environments.

Suitable for

• 10 Gigabit Ethernet network connections
• Server rooms and network racks
• Industrial environments with exposure to oils or abrasion
• Cable runs requiring screened S/FTP (S-STP) performance

How to use

Install the patch cable between RJ45 ports of network devices such as switches, routers, patch panels or servers. Route the cable to avoid sharp bends and excessive tensile stress; maintain bend radii recommended for Ethernet cables. Ensure connectors are fully inserted and locked into RJ45 sockets to secure a reliable connection.

Recommendations

For optimal performance, use the cable in network segments requiring Cat6a shielding and 10 Gigabit throughput. Avoid prolonged exposure to temperatures outside the cable's specified operating range and prevent mechanical damage from crushing or repeated sharp bending.
