PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Male

The PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Male, is a specialized passive interconnect cable designed for direct port-to-port connections in test, development, and diagnostic applications. This cable implements the standard PCIe communication protocol by crossing the Transmit (Tx) lanes from one end to the Receive (Rx) lanes on the opposite end, enabling two PCIe ports to communicate directly as if they were connected through a standard motherboard slot. Engineered for PCIe 3.0 systems, it supports a data rate of 8.0 GT/s per lane, providing a bandwidth of ~985 MB/s for x1 configurations. Constructed with low-loss materials and robust multi-layer shielding, this crossover jumper is ideal for benchtop testing, prototyping, and creating direct links between PCIe-based systems without requiring a motherboard host. The male-to-male design ensures a secure connection between two PCIe ports.

Features

• Standard Tx-to-Rx Cross Pinout: Implements the correct PCIe standard pin mapping by connecting the Transmit (Tx) channels of one port to the Receive (Rx) channels of the opposite port, enabling proper communication between two PCIe endpoints.
• PCIe 3.0 Compliance: Fully supports PCIe 3.0 specifications with a data transfer rate of 8.0 GT/s per lane while maintaining backward compatibility with PCIe 2.0/1.0 devices.
• Enhanced Signal Integrity: Utilizes multi-layer foil and braid shielding with low-loss dielectric materials to minimize insertion loss, crosstalk, and electromagnetic interference (EMI), ensuring stable performance at high speeds.
• Male Straight Connectors: Features standard PCIe male connectors with a straight orientation on both ends for direct mating with PCIe ports.
• Passive Design: Requires no external power or active components, utilizing high-quality copper conductors and precise impedance control for reliable signal transmission.
• Durable Construction: Built with gold-plated contacts (min. 0.76µm thickness) and reinforced connector housings to withstand repeated mating cycles in development and test environments.
