Achieve 40GBase-T Throughput with Low Latency
This cable supports 40GBase-T networking standards. The 2000MHz frequency enables up to four times higher throughput than Cat6a. You can connect 25G or 40G switches and NAS devices reliably. The S/FTP shielding minimises signal loss and EMI. So, your critical data transfers remain stable.
Ensure Safety with LSZH Jacket Material
The Low Smoke Zero Halogen jacket reduces toxic fumes during fire exposure. This makes it suitable for confined UK industrial settings and trains. It also meets building code considerations for residential installs. Because the jacket is flexible, it routes well in tight spaces. You get safer compliance without sacrificing durability.
Support PoE++ Devices with Pure Copper Conductors
This cable supports PoE++ (4PPoE) with a 100 W budget. The 26AWG pure bare copper wire improves conductivity and lowers resistance. You can power switches, access points, and IP cameras directly. Gold-plated connectors ensure a precise fit for over 750 mating cycles. In practice, this reduces connection wear over time.
Integrate Seamlessly with Existing Networks
The cable is backward compatible with Cat 6/6a and Cat 5/5e standards. You can upgrade specific links without replacing your entire infrastructure. Each cable is Fluke® DSX2-8000 tested for Cat8 performance. However, always verify your switch ports support 25G/40G speeds. Also, confirm your rack layout fits a 0.5m patch length.
