1. Double-layer shielding, more anti-interference Aluminum foil Mylar + magnesium wire braiding Shielding protection 1: Each two cores are wrapped with aluminum foil Mylar to reduce the environmental magnetic field. Shielding protection 2: Magnesium wire braided mesh densely wrapped to reduce signal interference. 2. Thickened wire core oxygen-free pure copper Using oxygen-free pure copper, it has good conductivity, small attenuation during transmission, stable transmission resistance, and fast transmission speed. 3. Eight-core twisted pair technology The four pairs of network cables will be twisted counterclockwise, and the distance between them is called "twist pitch". The twisted wire distances between the four pairs are different, but the twist pitch of each pair of wires is very uniform 4. -new environmentally friendly PVC/PE Using flexible PVC/PE materials, safe and flame-retardant, with certain wear resistance and oil-proof effects, it can adapt to various harsh outdoor environments 5. Three-pronged chip, pure copper gold-plated Using a three-pronged structure chip, the contact and the wire core are closely connected Thequartz head contact uses thickened gold-plated terminals, which are wear-resistant and anti-oxidation, with strong conductivity to reduce impedance, enhance contact conductivity, and ensure the stability of data transmission Product name: Category 8 double-layer shielded network cable / CAT8 Wire core: 4N-level OFC oxygen-free copper Shielding material: copper core + ground wire + aluminum foil multi-layer shielding Transmission rate: 40GBpS Transmission bandwidth: 2000Mhz Interface type: RJ-45 Wiring standard: EIA/TIA-568B Cable structure: four pairs 8 cores + double shielding structure Color: black Material: OFC oxygen-free copper Single set weight: 800g Packing method: bagged Single set contains: CAT8*1 Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-dadangjia
