PCIe 4.0 x1 to x1 Extension Cable, Male STR to Female STR

The PCIe 4.0 x1 to x1 Extension Cable, Male STR to Female STR is a high-performance passive extension cable designed for next-generation computing systems, data centers, and high-speed applications. This cable provides a reliable extension solution for PCIe 4.0 x1 interfaces using straight (STR) male and female connectors, enabling seamless data transmission between a host motherboard and PCIe devices (e.g., network cards, storage controllers, or specialized accelerators) while maintaining the enhanced bandwidth and signal integrity standards of PCIe 4.0. Engineered to support data rates up to 16.0 GT/s, this cable is ideal for applications requiring extended connectivity without compromising performance, such as high-density servers, test benches, or custom workstations.

Features

• PCIe 4.0 Compliance: Supports PCIe 4.0 specifications with a data transfer rate of 16.0 GT/s per lane, providing a bandwidth of ~1.969 GB/s for x1 configurations while ensuring backward compatibility with PCIe 3.0/2.0/1.0 devices.
• Straight Connector Design: Features straight (STR) male and female connectors with a standard PCIe x1 form factor, facilitating easy insertion and removal in confined spaces and ensuring compatibility with mainstream motherboards and devices.
• Enhanced Signal Integrity: Utilizes precision-engineered twin-axial cables (e.g., 85-ohm impedance, as seen in PCIe 4.0-specific designs) with multi-layer shielding (foil and braid) to minimize insertion loss, crosstalk, and electromagnetic interference (EMI), ensuring stable performance at high speeds.
• Passive Extension: Requires no external power or active components, relying on high-quality copper conductors (e.g., 31 AWG, common for PCIe 4.0 applications) and impedance matching to maintain signal integrity over extended lengths.
• Durable Construction: Incorporates gold-plated contacts (e.g., 0.76µm min. thickness, per PCI-SIG standards) and robust insulation materials (e.g., PVC) for corrosion resistance and longevity in commercial and industrial environments.
• Plug-and-Play Installation: Requires no drivers or software configuration, supporting hot-plug functionality (where enabled by the host system) for seamless integration.
