## Long description

The EFB Elektronik K5515.40 Black 40 m Cat6 S/FTP networking cable is a shielded twisted-pair cable designed for structured ethernet installations. It combines Cat6 performance with S/FTP shielding to reduce electromagnetic interference and maintain reliable throughput over a 40 metre run. The cable terminates in RJ-45 plugs with gold-plated contacts to ensure consistent connection and corrosion resistance, supporting data transfer rates up to 1000 Mbit/s for typical gigabit networks.
Advantages
S/FTP shielding—an overall foil shield combined with individually screened pairs—provides improved protection against crosstalk and external interference compared with unshielded cables. Gold-plated RJ-45 contacts improve contact reliability and reduce oxidation over time. The 40 m length offers flexibility for connecting devices across rooms or within office racks without additional patch panels. The black jacket delivers a neutral, professional appearance suitable for visible installations.
Suitable for
 Wired gigabit Ethernet connections in home or small office networks
 Connecting switches, routers and desktop computers across moderate distances
 Installation in environments with potential electromagnetic interference
 Temporary or semi-permanent cabling where a 40 m run is required
Key specifications
 Category: Cat6
 Shielding: S/FTP (overall foil + individually screened pairs)
 Length: 40 m
 Connectors: RJ-45 to RJ-45
 Contacts: gold-plated
 Maximum supported data rate: up to 1000 Mbit/s (gigabit)
 Colour: black
How to use
Route the cable avoiding sharp bends and sources of strong electromagnetic noise such as large transformers or heavy machinery. Insert each RJ-45 connector firmly into the corresponding network port until the latch clicks. For best performance, ensure both endpoints support gigabit speeds and that patch panels or switches are properly grounded when used in shielded installations. Trim excess cable length only when necessary and avoid kinking the jacket during installation.
Usage recommendations
For optimal signal quality, use this Cat6 S/FTP cable in shielded network environments and maintain proper grounding of connected equipment. When running cables alongside power lines, maintain separation distances and follow local installation standards. Test connections with a cable tester after installation to verify continuity, pairing and shielding integrity.
