Product Parameters

Conductor	Class 5 or higher annealed copper conductor (ultra-fine copper wires, extremely flexible), with a small cross-section ranging from 0.5 mm² to 2.5 mm² (common), optimized specifically for signal transmission.
Pair Structure	Insulated cores are precisely twisted in pairs with a fixed pitch, forming the physical foundation for signal integrity.
Insulation Material	Cross-linked polyethylene (XLPE), meeting Class B1 requirements for halogen-free, low-smoke, and flame-retardant properties.
Pair Shielding	Typically, an aluminum-plastic composite tape is wrapped around each twisted pair as pair shielding to prevent alien crosstalk between pairs.
Overall Shielding	A braided copper mesh or aluminum-plastic composite tape with a drain wire is used as overall shielding around all pairs to resist external interference.
Sheath Material	Halogen-free, low-smoke, flame-retardant polyolefin sheath, meeting overall Class B1 performance criteria.
Rated Voltage	300/300V, clearly indicating its signal transmission attributes.
Long-Term Operating Temperature	90°C
Combustion Performance Rating	Class B1 – The entire cable must pass all tests specified in GB 31247.
Halogen-Free and Low-Smoke	The entire structure complies with GB/T 17650.2 and GB/T 17651.2 (light transmittance ≥ 80%).
Heat Release and Toxicity	Meets Class B1 limits for THR and pHRR, as well as Class t1 toxicity requirements.
Burning Droplets	None.
Characteristic Impedance	Stable values, such as 100Ω ±15%, suitable for high-speed differential transmission.
Minimum Bending Radius	≥ 15×D (due to its extremely complex structure, bending requirements are particularly strict).
Shielding Effectiveness	High shielding attenuation at high frequencies (e.g., >90 dB @ 1 GHz), with excellent near-end crosstalk (NEXT) and attenuation-to-crosstalk ratio (ACR) performance.
Transmission Bandwidth	High, capable of supporting digital signal transmission at rates such as 100 Mbps, 1 Gbps, and beyond.
WDZB1N-RYJYSP	Fire resistance
