The PFM920I-6UN-CN is a UTP CAT6 network cable from Dahua, built for installers who need dependable, high-bandwidth cabling for IP camera systems, network switches, and structured Ethernet infrastructure. Supplied at 305 metres per carton, it’s suited to large-scale installations where consistent quality across long cable runs matters most.
At its core, the PFM920I-6UN-CN uses oxygen-free copper conductors at 99.95% purity, rated at 24AWG, which helps maintain signal integrity and minimise transmission loss over distance. The four twisted pairs are individually colour-coded for fast, accurate termination on site.
Performance is rated to standard CAT6 specifications, supporting a characteristic impedance of 100Ω ± 15Ω across the 4–250 MHz range, making the cable suitable for Gigabit Ethernet and Power over Ethernet applications, including IP camera deployments powered over the same cable run.
Construction includes HDPE-insulated conductors and a customized PVC outer sheath rated CE CPR Eca for flame retardancy, giving installers added confidence around fire safety compliance in commercial and residential settings. The cable is offered in grey, white, or orange sheath colours for easy identification across different installations.
One standout feature of the PFM920I-6UN-CN is its extended operating temperature range of –20°C to +75°C, wider than many standard CAT6 cables, making it a strong fit for installations in hotter climates or areas with elevated ambient heat, such as rooftop or industrial cable runs.
Each carton ships with 305 metres (1000 ft) of cable, and the cable passes low-temperature bending and heat shock testing without cracking, along with insulation shrinkage limits of 5% or less. Backed by a 10-year warranty, the PFM920I-6UN-CN is built for installers who want long-term, reliable performance.
For PoE-powered camera runs, network switch wiring, or structured cabling projects operating in demanding thermal environments, the PFM920I-6UN-CN is a dependable choice.
