Product Advantages

1. High-speed Shielded CableADT self-developed 4th generation shielded high-speed flat cable with premium connectors. Stable PCIe4.0 x1 transmission up to 16Gbps.
2. Customizable Length & Low ImpedanceCustom length available from 3cm to 100cm. Low impedance design. Full PCIe4.0 speed stable within 60cm cable length.
3. Differential Signal No Via DesignNo via holes for differential signal circuit. Eliminates signal attenuation and interference caused by parasitic capacitance & inductance. Prevent CAF micro-short circuit for long service life.
4. High-Quality PCB MaterialAdopts high-frequency low-resistance high TG PCB substrate. Copper thickness up to 1oz. Gold-plated fingers with sufficient gold content for excellent conductivity, preventing deadlock or audio issues caused by oxidation and rising impedance.
5. Robust Reinforced Structure3mm thick PCB gaskets protect metal soldering joints. Secured with screws and hex lock nuts. Anti-pull, anti-interference, avoids broken wires or pad drop-off.
6. Low-profile & Enlarged PCB DesignLow-profile PCB will not block graphics cards. Enlarged & lengthened PCB for easier installation and lower risk of damage.

Cable Specifications & Material

• Shielding: Full metal layer shielding, advanced EMI shielding conductive polymer flat cable. The conductive polymer fully covers the cable to block EMI ingress & emission, minimize signal interference and performance degradation while reducing cable weight.
• Cable Thickness: 1.3mm ultra-thin flat cable. Flexible and bendable without affecting performance.

Purchase & Operation Warnings

1. Installation Direction: Align connector direction correctly before plugging in. Reverse or offset insertion will burn your device. Hold the socket firmly when inserting, do not apply excessive force to avoid breaking pins.Do NOT bend or pull the cable within 2cm from soldering points on both ends.
2. Signal Loss Notice: Different motherboards and hardware have different signal driving capability. Signal loss is unavoidable with extension cables. Our internal test results may differ from your hardware environment. Not recommended for users requiring zero signal loss.
3. Hardware Compatibility: Older hardware will have worse stability after adding extension cables. NOT compatible with devices older than 4 years.
4. Application Scope: For professional engineer lab testing purpose only. Not for general consumer application.

Short FAQ

Q: What about cable quality and shielding?
A: It comes with full metal EMI shielding using conductive polymer material. Fully covered flat cable reduces electromagnetic interference and weight.

Q: Is the cable flexible and bendable?
A: Cable thickness is only 1.3mm. It is soft and bendable for installation without performance impact.
