Networking Cable EFB Elektronik K8051.40 40m Cat6a S/FTP Grey

The EFB Elektronik K8051.40 40m Cat6a S/FTP Grey networking cable provides a shielded, high-performance wired connection for local networks. Designed to support data transfer rates up to 10000 Mbit/s and the Cat6a standard, this cable is intended for applications requiring stable Gigabit and 10 Gigabit Ethernet connections. The cable has RJ-45 connectors with gold-plated contacts that reduce corrosion and help maintain consistent signal transmission over repeated insertions. The grey outer sheath offers a neutral appearance suitable for both home and professional installations.

Advantages

S/FTP shielding reduces electromagnetic interference by combining overall foil shielding with individually shielded pairs, improving signal integrity in environments with electrical noise. Cat6a specification ensures support for higher bandwidth and longer distances at 10 Gbps compared with lower category cables. Gold-plated RJ-45 connectors provide durable contact surfaces for reliable connectivity and minimized contact resistance. The 40 m length covers longer cable runs without the need for additional patching or couplers, simplifying network layout.

Suitable for

• 10 Gigabit Ethernet links in server rooms and data closets
• High-speed home networking for media streaming and large file transfers
• Office workstations and networked printers requiring stable wired connections
• Structured cabling runs where reduced EMI is necessary (near power lines or electrical equipment)

Key specifications

• Category: Cat6a (augmented Category 6)
• Shielding: S/FTP — overall foil with individually shielded twisted pairs
• Length: 40 metres
• Maximum supported data rate: up to 10000 Mbit/s (10 Gbit/s)
• Connectors: RJ-45 with gold-plated contacts
• Color: grey outer sheath
• Suitable frequency range: Cat6a standard (up to 500 MHz)

How to use

Uncoil the cable carefully to avoid kinks and run it along cable trays, under floor channels, or along walls as required by your installation. Terminate both ends into compatible RJ-45 ports on networking equipment such as switches, routers, or network interface cards. Ensure connector locking tabs are not obstructed and that connectors are fully seated to establish a reliable link. For optimal performance, avoid sharp bends (maintain the manufacturer’s minimum bend radius) and keep the cable separated from high-voltage power lines to reduce potential interference.

Recommendations

Use this Cat6a S/FTP cable for runs where consistent 10 Gbit/s performance and immunity to electromagnetic interference are important. If routing through tight conduit or around multiple tight corners, verify the bend radius and consider shorter cable paths or additional cable management to prevent signal degradation.
