PCIe 4.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Male

The PCIe 4.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Male is a specialized high-performance interface solution designed for unique connectivity scenarios requiring precise signal crossover between transmission (Tx) and reception (Rx) lanes. This cable features PCIe 4.0 x1 male connectors on both ends, 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 3M™ 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, particularly in enterprise equipment and data center computing devices.
