## Summary description

EFB Elektronik K5539WS.5 is a 5 m networking cable meeting Cat6a standard with S/FTP (S‑STP) shielding. Both ends use RJ‑45 connectors with gold‑plated contacts for reliable signal transfer and corrosion resistance. Designed for high‑speed Ethernet and structured cabling, it suits LAN installations, switches, routers and patch panels where reduced crosstalk and improved noise immunity are required.

## Long description

EFB Elektronik K5539WS.5 Cat6a S/FTP (S‑STP) RJ‑45 — 5 m is a 5‑metre network patch cable engineered to meet the Cat6a standard. The cable features S/FTP (S‑STP) shielding construction and RJ‑45 connectors with gold‑plated contacts to ensure stable signal transmission and corrosion resistance. It is intended for high‑speed Ethernet and structured cabling environments where reduced crosstalk and better immunity to electromagnetic interference are required.
Advantages
The S/FTP (S‑STP) shielding combines an overall foil with individually shielded pairs to minimize alien crosstalk and protect data integrity in dense cabling installations. Gold‑plated contacts on both RJ‑45 plugs provide reliable mating and lower contact resistance over time. The cable is manufactured to Cat6a specifications, supporting the higher bandwidth and reduced return loss necessary for 10 Gigabit Ethernet links at shorter to medium distances within LAN environments.
Suitable for
10 Gigabit Ethernet links in office and data centre LANs
Patch panels, switches and routers requiring shielded cabling
Structured cabling where reduced electromagnetic interference is needed
High‑density cabling runs near power lines or other potential noise sources
Key specifications
Category: Cat6a
Shielding: S/FTP (overall foil with individually shielded pairs)
Connector type: RJ‑45 on both ends
Contact plating: gold‑plated contacts
Length: 5 m
Application: Ethernet, structured cabling, patching
How to use
Connect one RJ‑45 plug to the network device (switch, router, network card) and the other plug to the corresponding port on the patch panel or endpoint device. Ensure connectors are fully inserted until the latch engages and verify link status on network devices. For optimal performance, avoid excessive bending radii and keep the cable routed away from strong EMI sources where possible.
Usage recommendations
For reliable 10 Gigabit performance, use within typical horizontal link lengths and adhere to installation practices for shielded cables: maintain proper grounding at patch panels or shielded connectors, avoid sharp bends, and separate from power cabling to reduce interference.
