Wentronic Goobay CAT 8.1 Patch Cable, S/FTP (PiMF), Black, 3 m - LSZH Halogen-Free, Copper AWG 24 (66723)

For high-speed networks where every millisecond counts, this Goobay CAT 8.1 patch cable delivers 40 Gbit/s over 3 metres without compromise. Unlike standard Cat6a or Cat7 cables that top out at 10 Gbit/s, the S/FTP (PiMF) shielding with individually foiled pairs and an overall braid eliminates alien crosstalk, making it the reliable backbone for 25G/40GBase-T data centres and enterprise server rooms. The LSZH jacket means no toxic smoke or corrosive halogens in case of fire, so it is safe for enclosed spaces. With gold-plated RJ45 connectors and stranded AWG 24 copper conductors, this cable combines durability, flexibility, and signal integrity in one black, halogen-free design.

Highlights

• Category 8.1 performance: 2000 MHz bandwidth, 40 Gbit/s data rate
• S/FTP (PiMF) shielding: each pair in metal foil plus overall braid for maximum noise immunity
• LSZH (Low Smoke Zero Halogen) jacket: fire-safe, low smoke, no corrosive gases
• Gold-plated RJ45 connectors: corrosion-resistant, reliable contact
• Stranded AWG 24 copper conductors: flexible yet high-performance
• PoE support up to 4PPoE: power and data over one cable
• 3 m length: ideal for patch panels, servers, and workstation connections

In daily use

This cable is built for high-density environments. The slim, black LSZH jacket is easy to route through cable managers, and the stranded conductors make it flexible enough for tight bends behind racks. Because it is halogen-free, it meets strict fire safety regulations for public buildings, hospitals, and data centres. The gold-plated contacts maintain a stable connection even after hundreds of mating cycles, and the robust strain relief protects the cable at the connector. Whether you are upgrading a server rack or connecting a high-performance workstation, this patch cable ensures your network runs at full speed without interference.
