PCIe 3.0 x1 Tx to Tx Straight Through Jumper Cable, Male to Male

The PCIe 3.0 x1 Tx to Tx Straight Through Jumper Cable, Male to Male, is a specialized passive interconnect solution designed for advanced hardware debugging, signal integrity validation, and custom point-to-point applications. This cable features a non-standard pinout where the Transmit (Tx) lanes on one end are directly connected to the Transmit (Tx) lanes on the opposite end, deviating from the typical PCIe communication protocol (which requires Tx to connect to Rx). 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 jumper is intended for use in controlled test environments, prototype development, or specialized computing setups where a direct Tx-to-Tx link is explicitly required. The straight-through male-to-male design ensures a simple, rigid connection between two PCIe ports.

Features

• Tx-to-Tx Direct Pinout: Features a non-standard straight-through pin mapping that directly connects the Transmit (Tx) channels of one PCIe port to the Transmit (Tx) channels of another, essential for specific testing and debugging scenarios.
• PCIe 3.0 Compliance: Supports PCIe 3.0 specifications with a data transfer rate of 8.0 GT/s per lane while maintaining electrical compatibility with PCIe 2.0/1.0 devices.
• High-Frequency Shielding: Incorporates multi-layer foil and braid shielding to minimize crosstalk, attenuation, and electromagnetic interference (EMI), preserving signal integrity for high-speed data transfers.
• Male Straight Connectors: Utilizes standard PCIe male connectors with a straight orientation on both ends for a direct port-to-port connection.
• Passive Design: Requires no external power or active components, relying on high-quality copper conductors and precise construction for signal transmission.
• Durable Construction: Built with gold-plated contacts (e.g., min. 0.76µm thickness) and reinforced connector housings to withstand repeated mating cycles in a lab or test bench environment.
