PCIe 4.0 x1 Tx to Tx Straight Through Jumper Cable, Female to Female

The PCIe 4.0 x1 Tx to Tx Straight Through Jumper Cable, Female to Female is a high-performance interface extension solution designed to provide seamless, unaltered signal transmission between two PCIe 4.0 x1 interfaces. This cable features identical PCIe 4.0 x1 female connectors on both ends, with a straight-through pinout that maintains Tx-to-Tx and Rx-to-Rx connections without crossover. Engineered for reliability and signal integrity, this cable utilizes 85? low-impedance twin-axial cable technology (e.g., 31 AWG signal wires, as seen in premium designs like 3M™ Twin Axial Cable) to minimize signal degradation and ensure high-speed data transfer. It is ideal for test benches, debugging setups, server upgrades, and applications requiring precise signal replication or extension between PCIe devices without signal re-routing.

Features  

• Straight-Through Signal Path: Maintains unaltered Tx-to-Tx and Rx-to-Rx connections between identical PCIe 4.0 x1 female interfaces, ensuring signal integrity without crossover.  
• High-Speed Performance: Supports PCIe 4.0 specifications with data transfer rates up to 16 GT/s (16 Gbps, 2 GB/s per lane for x1), ensuring full PCIe 4.0 bandwidth for expansion cards.  
• Low Impedance: Optimized 85? impedance matching (per PCIe 4.0 standards) ensures minimal signal degradation and superior signal integrity, utilizing technologies like 3M™ Low Loss Twin Axial Cable.  
• Enhanced Compatibility: Compatible with PCIe 4.0/3.0/2.0 protocols and works with both Intel and AMD motherboards. Compatible with Card Electromechanical (CEM) connectors.  
• Secure Connection: Precision-engineered female connectors ensure reliable mating and stable operation with standard PCIe x1 devices.  
• Durable Construction: High-quality materials (e.g., gold-plated contacts: min. 0.76µm gold thickness per premium specs, braided shielding) ensure longevity and repeated use. Features EMI shielding (e.g., conductive tape or absorbent materials) to reduce electromagnetic interference.  
• Flexible & Foldable Design: Utilizes thin, flat twin-axial cable (e.g., 3M™ Low Loss Twin Axial Cable with 31 AWG wires) that can be folded or bent (with an extremely small bend radius) without significantly affecting electrical performance, saving space and enabling unique packaging in dense servers.
