DDS / DNC-LSZHBC305 / UTP LSZH 23AWG ( Pass FLUKE Test ) 305M Cat6 Roll

Premium LSZH Cat6 Cable for Safe, High-Performance Networks

The DDS / DNC-LSZHBC305 / UTP LSZH 23AWG ( Pass FLUKE Test ) 305M Cat6 Roll is a premium-grade, fire-safe structured cabling solution from DDS — engineered for high-performance LAN installations in offices, hospitals, schools, data centres, and public buildings where Low Smoke Zero Halogen (LSZH) compliance is mandatory. Built on a 23 AWG solid bare copper conductor with high-density PE insulation, this cable fully complies with Cat6 specifications and exceeds the requirements of both ANSI/TIA-568-C.2 and ISO/IEC 11801 standards. Furthermore, every roll carries a verified FLUKE test pass certificate, giving installers and end clients absolute confidence in the cable’s electrical performance before a single patch cord is terminated. Consequently, project sign-off and compliance documentation become straightforward on any structured cabling installation.

LSZH Jacket — Fire Safety Where It Matters Most

The DDS / DNC-LSZHBC305 uses a Low Smoke Zero Halogen (LSZH) outer jacket — the critical difference between this roll and standard PVC-jacketed Cat6 cable. In the event of a fire, LSZH compounds emit minimal smoke and release no toxic halogen gases, protecting building occupants and first responders from dangerous fumes in enclosed spaces such as corridors, ceiling voids, and cable risers. Additionally, the jacket thickness of 0.55±0.05 mm and outer diameter of 6.3±0.4 mm keep the cable profile compact for clean installation through conduit, cable trays, and containment systems. Moreover, the included rip cord simplifies jacket stripping during termination, saving time on every connection point across large-scale deployments.

Electrical Performance Built for Gigabit & Beyond

This cable operates at a bandwidth of 250 MHz and supports Gigabit Ethernet (1000BASE-T) and all standard LAN protocols. The 23 AWG solid bare copper conductor delivers a DC resistance of 73 Ω/km nominal, with a maximum resistance unbalance of just 4% — ensuring consistent pair-to-pair performance across the full 305-metre roll. Furthermore, the impedance of 100 Ω ±15 Ω and capacitance unbalance of 3.3 pF/m maximum guarantee excellent signal integrity and minimal crosstalk throughout. Additionally, a propagation delay skew of 35 ns/100m maximum and velocity of propagation of 69% meet all Cat6 timing requirements for high-speed data applications. The colour code follows TIA/EIA 568-B standard across all 4 pairs for consistent, error-free termination every time.

Practical Packaging & Installation Features

The DDS / DNC-LSZHBC305 / UTP LSZH 23AWG ( Pass FLUKE Test ) 305M Cat6 Roll arrives packaged in a convenient reel-in-box format for easy, tangle-free cable pulling on site — reducing installation time and cable damage during deployment. The operating temperature range of -10°C to +65°C covers all standard indoor environments, while the storage temperature range of -30°C to +60°C ensures the cable retains its performance characteristics in warehouse or on-site storage conditions. Whether you are cabling a hospital ward, fitting out a school network, or completing a large commercial office installation, this cable delivers the fire safety, electrical performance, and verified compliance your project demands.
