ADT factory direct sales, product performance is excellent, product with super good reputation, 100% fully inspected and energized for delivery. Brand: ADT-LINK Product model: R51JF 4.0 Product name: M.2-AE key to PCIE4.0 X1 adapter board extension cable Wire length: 3-100cm (support wire length customization) Speed bandwidth: PCIe4.0x1 gen4 8G/bps Product function: M.2 NVME SSD is connected to the M.2 WiFi interface of the motherboard through an extension cable Purchase restriction: only designated by professional engineers for purchase, general purpose is not suitable and cannot be used, ordinary buyers do not purchase. Procurement Tips: Be sure to buy 1~2 samples first, and then buy them in bulk after testing and verifying that they are correct. Product advantages: 1. Wire advantage, using German patented imported wire, using Taiwan imported connector, supporting PCIe 3.0 full-speed stable transfer 2. Cable length advantage, from 3 cm to 1 meter can be customized, the adapter sold in our shop, the cable impedance is low, the cable length within 60 cm supports PCIe3.0 full speed. 3. Differential signal has no via hole design, there is no signal attenuation interference problem of parasitic capacitance and parasitic inductance, and there will be no CAF micro short circuit phenomenon, and the product is durable 4. The product is made of high-quality materials, the PCB is made of precision, the thickness of the copper material is thickened to 1oz, the gold plated content is sufficient, and the gold plated foot has good electrical conductivity, which can reduce the blue screen of crash caused by the increase of oxidation and rust resistance. Stable at full speed, no speed reduction required, and no compatibility issues. 5. The wire used in the product is very durable. Use PCB gaskets with a thickness of 3mm at the metal welding points, and lock the screws and hexagonal nuts to fasten it. The product is strong and reliable, resistant to pulling, anti-interference, and will not break the wire. The nail drop problem. The wire can be bent or folded without affecting the use. 6. The PCB is designed with short and fattening, which will not get stuck on the graphics card. The fattening and long design makes the board easier to install and reduces the chance of damage.
