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

The PCIe 3.0 x16 Male to x16 Female Up R/A Extension Cable is a passive interconnect solution engineered for full-bandwidth PCIe 3.0 extension with optimized spatial efficiency. This cable preserves 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 maintains backward compatibility with PCIe 2.0/1.0 devices. The design incorporates an Up Right-Angle (Up R/A) female connector that directs the cable upward relative to the motherboard plane, significantly reducing mechanical obstruction and cable stress in vertical GPU installations or compact chassis. Utilizing advanced twin-axial cable technology, such as 3M's Twin Axial Cable which allows for high-performance signal integrity even when folded or bent, this cable ensures minimal signal degradation. The construction features multi-layer EMI shielding and robust materials for reliable performance in demanding environments.

Features

• Full x16 Lane Support: Preserves all 16 PCIe lanes, ensuring maximum bandwidth utilization of approximately 15.75 GB/s for high-end devices like GPUs.
• Up Right-Angle Connector: The Up R/A female connector (90-degree design) facilitates upward cable routing, minimizing interference and improving airflow management in cramped enclosures.
• PCIe 3.0 Compliance: Supports PCIe 3.0 specifications with 8.0 GT/s per lane data transfer, leveraging 128b/130b encoding for efficient transmission.
• Enhanced Signal Integrity: Employs twin-axial cable technology (e.g., 3M Twin Axial Cable) and multi-layer 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 precise impedance control for plug-and-play operation.
• Durable Construction: Incorporates reinforced connector housings and strain relief to withstand mechanical stress, with a typical durability rating of 500 insertion cycles.
