PCIe 3.0 x16 Male to x16 Female Down R/A Extension Cable

The PCIe 3.0 x16 Male to x16 Female Down R/A Extension Cable is a passive interconnect solution designed for full-bandwidth PCIe 3.0 extension with optimized spatial efficiency in low-clearance environments. This cable maintains all 16 PCIe lanes, supporting a data transfer rate of 8.0 GT/s per lane and delivering a total bandwidth of approximately 15.75 GB/s without lane reduction. It features backward compatibility with PCIe 2.0/1.0 devices. The design incorporates a Down Right-Angle (Down R/A) female connector that directs the cable downward relative to the motherboard plane, minimizing vertical profile and mechanical obstruction in space-constrained systems such as 1U/2U servers or compact workstations. Constructed with impedance-controlled wiring and multi-layer EMI shielding, this cable ensures reliable signal integrity while addressing challenging routing requirements in high-density configurations.
