## Summary description

EFB Elektronik K5539WS.3 is a 3 m network patch cable compliant with Cat6a standard. It features S/FTP (S‑STP) shielding for improved protection against electromagnetic interference and gold‑plated RJ‑45 contacts for reliable connectivity. Designed for high‑speed Ethernet links, it is suitable for professional and home networks, switches, routers and patch panels.

## Long description

EFB Elektronik K5539WS.3 Cat6a S/FTP (S‑STP) 3 m patch cable in white is designed for high‑speed Ethernet connections in professional and home network environments. The cable meets Cat6a specifications for 10 Gigabit Ethernet over copper, and uses S/FTP shielding (overall braid with individually foil‑shielded pairs) to reduce crosstalk and external electromagnetic interference. Gold‑plated RJ‑45 terminations provide corrosion resistance and consistent contact performance for reliable data transmission in switches, routers, patch panels and network interfaces.
Advantages
The S/FTP (S‑STP) construction offers enhanced protection against near‑end crosstalk and external EMI compared with unshielded or partially shielded cables, improving signal integrity for demanding data rates. Gold‑plated RJ‑45 contacts increase durability and maintain low contact resistance over repeated insertions. The 3 m length provides flexible placement options in rack, desk or wall‑mounted installations while the white jacket supports discreet routing in modern interiors.
Suitable for
10 Gigabit Ethernet links within data centers, server rooms and office networks
Connections between switches, routers and patch panels
Home networking where EMI protection is required (near appliances or power wiring)
Workstation or AV installations requiring short to medium cable runs
Key specifications
Category: Cat6a, supports 10 Gbps Ethernet
Shielding: S/FTP (overall braid with individually foil‑shielded pairs)
Connectors: RJ‑45 to RJ‑45 with gold‑plated contacts
Length: 3 meters
Color: White
Conductor configuration: Twisted pair, 4 pairs
Bandwith: Suitable for frequencies up to 500 MHz (Cat6a specification)
How to use
Insert each RJ‑45 plug firmly into the corresponding port on network devices such as switches, routers or patch panels until the latch clicks. Route the cable avoiding sharp bends and excessive tension; maintain bend radius recommended for twisted pair cables to preserve performance. For installations where shielding continuity matters, ensure connectors and connected devices provide proper ground or shield termination. Test the link using a cable tester or network diagnostic tool to verify correct pair wiring and signal performance after installation.
Usage recommendations
Use this Cat6a S/FTP patch cable for short to medium runs where higher immunity to electromagnetic interference is required. For full shielding benefits in structured cabling, pair with shielded connectors and properly grounded patch panels or outlets. Avoid running the cable parallel and in close proximity to high‑voltage power lines for extended distances to minimize potential interference.
