Product Advantages
✅ ADT Self-developed 4th Generation Shielded High-Speed CablePremium connectors are adopted, supporting stable PCIe 4.0 x1 transmission at high frequency.
✅ Custom Cable Length AvailableCustom lengths from 3cm to 100cm. Low cable impedance. Stable full-speed PCIe4.0 performance within 60cm length.
✅ Differential Signal Via-Free DesignEliminates parasitic capacitance & inductance signal attenuation and interference. No CAF micro-short issues for long service life.
✅ High-frequency Low-impedance PCBPrecision PCB made of high TG substrate with 1oz thick copper. Gold-plated fingers with sufficient gold content deliver great conductivity. Reduce risk of crash or audio distortion caused by oxidation and rising impedance.
✅ Solid & Durable Structure3mm thick PCB gaskets protect metal solder joints, fastened with screws and hex lock nuts. Tear-resistant, anti-interference, prevents wire breakage and pin drop.
✅ Low-profile & Reinforced PCB DesignLow-profile design avoids GPU blocking. Extended reinforced PCB for easier installation and lower damage risk.
FAQ
Q: What about cable quality? Is it shielded?A: It comes with metal layer shielding. Adopts advanced EMI shielding conductive polymer material for flat cable. The conductive polymer fully covers each cable for EMI protection, blocks incoming & outgoing electromagnetic frequency radiation, minimizes interference and performance degradation while reducing cable weight.
Q: Cable thickness? Flexible? Bendable?A: Cable thickness only 1.3mm. The flat cable is soft and bendable. Normal bending will not affect performance.
Important Purchase Notice
⚠️ This item is intended for purchase by professional engineers only. NOT for general consumer use. General buyers please DO NOT buy.
- Confirm the connector direction before plugging in. Reverse or offset insertion may burn your device. Hold the device socket firmly during plug-in; do not apply excessive force to avoid pin breakage. Do NOT bend or pull the cable within 2cm of soldering points on both ends.
- Motherboards and hardware have different signal driving capability. Our in-house test results may differ from your environment. Signal loss is inevitable with extension cables. Do NOT purchase if you require absolutely zero signal loss.
- GPUs and motherboards degrade and oxidize over time. Adding extension cables will further reduce stability. NOT compatible with hardware older than 4 years.
- For engineering test purposes only. Not for other applications.
- Sample test recommended: Please order 1~2 samples first for verification before bulk purchase.
- Compatibility issues are common. Improper assembly or operation may damage your hardware. This is a custom product, non-returnable & non-refundable. Please fully confirm before checkout.
Length Explanation
The listed cable length refers only to the flat cable body, excluding PCB and connectors. PCB+connectors add approximately 3cm to the overall total length. For example, 5cm cable body gives total length around 8cm.
