PCIe 3.0 x4 Male to x4 Female Extension Cable

The PCIe 3.0 x4 Male to x4 Female Extension Cable is a passive interconnect solution designed to extend the reach of PCIe devices in systems where direct motherboard slot access is limited or unavailable. This cable maintains the full x4 lane configuration, supporting a total bandwidth of approximately 3.94 GB/s (at PCIe 3.0 speeds of 8.0 GT/s per lane) while ensuring compatibility with PCIe 3.0/2.0/1.0 devices. Constructed with impedance-controlled wiring (targeting 85 ohms differential) and multi-layer shielding, it minimizes signal degradation over extended distances. Ideal for test benches, mining rigs, custom workstations, and space-constrained enclosures, this cable enables flexible placement of add-in cards such as SSDs, NICs, or specialized controllers without sacrificing performance .
