PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Female Up R/A

The PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Female Up R/A is a specialized high-performance interface solution designed for unique connectivity scenarios requiring signal crossover between transmission (Tx) and reception (Rx) lanes with upward right-angle orientation. This cable features a PCIe 3.0 x1 male connector on one end and an upward right-angle (Up R/A) PCIe 3.0 x1 female connector on the other end, with internal wiring that crosses Tx and Rx pairs to enable specific testing, debugging, or custom configuration requirements. Engineered for exceptional signal integrity, this cable utilizes 85? low-impedance twin-axial cable technology (e.g., 31 AWG signal wires, as utilized in premium designs) to minimize signal degradation and ensure high-speed data transfer. It is ideal for advanced testing environments, development setups, and specialized applications where conventional straight-through cables cannot meet specific signal routing needs.

Compatibility Notes  

This cable is designed for specialized applications requiring Tx/Rx crossover. The upward right-angle female connector is ideal for environments where vertical space is limited and cable routing must avoid obstruction (e.g., above PCB trays). Ensure the host system's PCIe slot supports PCIe 3.0 or earlier versions (2.0/1.0) for backward compatibility. Note: This is not a standard extension cable and should only be used in specific scenarios where signal crossover is explicitly required.
