PCIe 4.0 x16 Male to x1 Female Up R/A Extension Cable

The PCIe 4.0 x16 Male to x1 Female Up R/A Extension Cable is a high-performance passive interconnect solution engineered for next-generation systems requiring adaptive connectivity between different PCIe slot sizes while maintaining PCIe 4.0 compliance and optimized spatial efficiency. This cable converts a larger PCIe x16 slot interface into a smaller PCIe x1 interface, supporting a data transfer rate of 16.0 GT/s per lane and delivering a bandwidth of approximately 2 GB/s for the x1 interface, with backward compatibility to PCIe 3.0/2.0/1.0 devices. The design incorporates an Up Right-Angle (Up R/A) female connector that optimizes vertical clearance by directing the cable upward relative to the motherboard plane, reducing mechanical obstruction in dense configurations such as compact workstations or servers requiring vertical space optimization. Constructed with 85-ohm impedance-matched wiring and multi-layer shielding, this cable minimizes signal degradation while addressing mechanical routing challenges in high-speed applications.

Features

• Form Factor Adaptation: Enables physical and electrical compatibility between PCIe x16 and x1 interfaces, allowing x1 devices to be installed in x16 slots while operating at x1 lane speeds.
• Up Right-Angle Connector Optimization: The Up R/A female connector facilitates upward cable routing, minimizing interference with adjacent components and improving airflow management in cramped enclosures.
• PCIe 4.0 Compliance: Supports PCIe 4.0 specifications with a data transfer rate of 16.0 GT/s per lane, providing approximately 2 GB/s bandwidth for the x1 interface.
• 85-Ohm Impedance Matching: Precisely controlled differential impedance reduces signal reflections and ensures signal integrity at 16.0 GT/s data rates.
• Enhanced Signal Integrity: Utilizes low-loss twin-axial cables with multi-layer foil and braid shielding to minimize insertion loss, crosstalk, and electromagnetic interference.
• Passive Design: Requires no external power or active components, relying on high-quality copper conductors and robust construction for reliable operation.
• Durable Construction: Incorporates gold-plated contacts and reinforced housings with strain relief to withstand mechanical stress in demanding environments.
