Model SpecificationModelDescriptionM88AAPCIe 4.0 x8 to x8, male edge to male edge, straight signal routing extension cableM88ABPCIe 4.0 x8 to x8, male edge to male edge, Tx-Rx cross signal routing extension cableK88VSPCIe 4.0 x8 to x8, male edge to male edge, straight signal routing extension cableK88NSPCIe 4.0 x8 to x8, male edge to male edge, Tx-Rx cross signal routing extension cableProduct Advantages- Shielded High-Speed Flat CableADT self-developed 4th-generation EMI-shielded high-speed cable with premium connectors, stable PCIe 4.0 high-frequency signal transmission.
- Customizable Cable LengthCustom lengths available from 3cm up to 100cm. Low impedance cable design maintains full-speed PCIe 4.0 performance stably within 60cm.
- Via-less Differential Signal PCB DesignEliminates signal attenuation and interference caused by parasitic capacitance and inductance. Prevents CAF conductive anodic filament micro-short faults for extended service life.
- High-Grade High Frequency PCBAdopts high-TG, low-loss high-frequency PCB substrate with 1oz thick copper plating. Gold-plated edge fingers deliver excellent conductivity. Reduces system crash and signal distortion caused by oxidation and rising contact impedance.
- Robust Mechanical Reinforcement3mm thick PCB reinforcement pads at soldering joints, secured with screws and hex nuts. Tear-resistant and anti-interference construction, prevents broken conductors and lifted pins.
- Optimized PCB ProfileLow-profile PCB avoids GPU collision. Widened & lengthened PCB improves installation simplicity and reduces damage risk.
Cable Quality & ShieldingThe flat cable is fully shielded with advanced EMI conductive polymer shielding material. Each flat conductor is fully wrapped by conductive polymer shielding to block incoming and outgoing electromagnetic radiation. It minimizes EMI interference, reduces signal degradation, and lowers overall cable weight.
Important Notes- Correct Orientation RequiredVerify connector direction before plugging in. Reversed or offset insertion may permanently damage your hardware. Hold the socket firmly during installation, do not apply excessive force to avoid pin breakage.Do NOT bend or pull the cable within 2cm of the soldering joints on both cable ends.
- Signal Loss DisclaimerMotherboards and host devices vary in signal driving capability. Our internal test results cannot guarantee identical performance on your hardware. Signal loss is unavoidable when using extension cables. Do not purchase if you require zero-signal-loss performance.
- Hardware Age CompatibilityGPUs and motherboards degrade and oxidize over time. Adding an extension cable will further reduce stability. Not compatible with hardware older than 4 years.
- Usage RestrictionFor professional engineers and lab testing purposes only. Not permitted for other applications.
