PCIe 3.0 x4 Male to x4 Female Up R/A Extension Cable

The PCIe 3.0 x4 Male to x4 Female Up R/A Extension Cable is a high-speed passive interconnect solution designed to extend the reach of PCIe devices in systems where direct motherboard slot access is limited or requires spatial reconfiguration. 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 backward compatibility with PCIe 2.0/1.0 devices. The incorporation of an Up Right-Angle (Up R/A) connector optimizes vertical clearance, facilitating efficient cable routing in densely packed enclosures such as servers, test benches, or custom workstations. Engineered with impedance-controlled wiring (targeting 85 ohms differential) and multi-layer shielding, it minimizes signal degradation over extended distances. Ideal for applications demanding flexible card placement without sacrificing electrical performance, this cable enables reliable connections for add-in cards like NVMe SSDs, network adapters, or specialized controllers.

Features

• Full x4 Lane Support: Preserves all four PCIe lanes, ensuring maximum bandwidth utilization (~3.94 GB/s for PCIe 3.0) for devices requiring x4 electrical interfaces.
• Up Right-Angle Connector: The Up R/A design (typically on the female end) directs the cable upward relative to the motherboard plane, reducing mechanical obstruction and improving airflow in space-constrained configurations.
• 85-Ohm Impedance Control: Precisely engineered to meet PCIe 3.0/4.0 specifications for differential impedance, reducing signal reflections and ensuring integrity at high data rates.
• Enhanced Shielding: Utilizes multi-layer foil and braid shielding to minimize crosstalk and electromagnetic interference (EMI), critical for stable operation in electrically noisy environments.
• Passive Design: Requires no external power or active components, leveraging high-quality copper conductors (e.g., 31–32 AWG) for reliable signal transmission.
• Durable Construction: Features gold-plated contacts (e.g., ?0.76µm thickness) and reinforced connectors rated for ?500 insertion cycles, suitable for frequent reconfigurations in development or industrial settings.
