PCIe 3.0 x16 Male to x1 Female Extension Cable

The PCIe 3.0 x16 Male to x1 Female Extension Cable is a specialized passive interconnect solution designed for scenarios requiring physical and electrical adaptation between significantly different PCIe slot sizes. This cable converts a larger PCIe x16 slot interface into a smaller PCIe x1 interface, supporting a data transfer rate of 8.0 GT/s per lane while delivering a bandwidth of approximately 985 MB/s for the x1 interface. The cable maintains backward compatibility with PCIe 2.0/1.0 devices and is constructed with impedance-controlled wiring targeting 85-ohm differential characteristics with multi-layer shielding. This solution addresses form-factor adaptation challenges in space-constrained environments such as test benches, custom workstations, or specialized computing setups where flexible card placement is essential.

Features

• Form Factor Adaptation: Enables physical compatibility between PCIe x16 and x1 interfaces, allowing x1 devices to be installed in x16 slots while operating at x1 lane speeds.
• PCIe 3.0 Compliance: Supports PCIe 3.0 specifications with a data transfer rate of 8.0 GT/s per lane, providing approximately 985 MB/s bandwidth for the x1 interface.
• Enhanced Signal Integrity: Utilizes multi-layer foil and braid shielding to minimize crosstalk and electromagnetic interference, ensuring stable performance in various operating environments.
• Passive Design: Requires no external power or active components, relying on high-quality copper conductors and precise impedance control for reliable signal transmission.
• Durable Construction: Incorporates robust materials including gold-plated contacts and reinforced connector housings rated for multiple insertion cycles in commercial environments.
• Space-Efficient Solution: Facilitates flexible installation in cramped enclosures where standard x1 slots may be unavailable or obstructed.
