PCIe 4.0 x16 Male to x16 Female Extension Cable

The PCIe 4.0 x16 Male to x16 Female Extension Cable is a high-performance passive interconnect solution designed for full-bandwidth PCIe 4.0 extension applications. This cable maintains all 16 PCIe lanes while supporting the doubled data transfer rate of 16.0 GT/s per lane compared to PCIe 3.0, delivering a total theoretical bandwidth of approximately 31.5 GB/s. It features precision-engineered connectors with advanced signal integrity preservation techniques to handle the increased speed requirements of the PCIe 4.0 specification. The cable utilizes specialized low-loss dielectric materials and controlled impedance pathways to minimize signal degradation and maintain timing accuracy. Constructed with multi-layer EMI/RFI shielding, this extension solution ensures reliable operation in electrically noisy environments while providing flexible physical placement of PCIe devices. It is backward compatible with PCIe 3.0/2.0/1.0 devices.
