The PFM920I-6U-C is a UTP CAT6 network cable from Dahua, built for installers who need reliable, high-bandwidth cabling for IP camera systems, network switches, and structured Ethernet installations. Supplied at 305 metres per carton, it’s designed for large-scale projects where consistent cable quality across long runs matters.
At its core, the PFM920I-6U-C uses high-purity oxygen-free copper conductors at 99.97% purity, rated at 23AWG, a slightly thicker gauge than some CAT6 alternatives, which helps reduce DC resistance and supports stronger signal transmission over distance. The four colour-coded twisted pairs make termination and troubleshooting straightforward on site.
Performance is rated to standard CAT6 specifications, with a characteristic impedance of 100 ± 15Ω and near-end crosstalk of at least 39.3 dB per 100 metres at 250 MHz. These figures support Gigabit Ethernet and Power over Ethernet applications, including PoE-powered IP camera runs carried over the same cable.
Construction includes HDPE-insulated conductors and a customized PVC outer sheath rated CE CPR Eca for flame retardancy, giving installers added assurance around fire safety compliance in commercial and residential buildings. A built-in rip cord speeds up stripping and termination during installation.
The PFM920I-6U-C is tested to ISO/IEC 11801-1-2017 and IEC 61156-5-2009 standards, and passes low-temperature bending and heat shock tests without cracking. Operating temperature ranges from –20°C to +60°C, with installation temperature rated between 0°C and +50°C, suiting a wide range of climates and job sites.
Each carton ships with 305 metres (1000 ft) of cable, packaged with two inner cartons inside one outer carton for easier handling and storage. Backed by a 10-year warranty, the PFM920I-6U-C is built for installers who want dependable, long-lasting cabling performance.
For PoE-powered camera deployments, network switch wiring, or any structured cabling project that needs consistent CAT6 performance at scale, the PFM920I-6U-C is a dependable choice.
