In high-density AI servers, enterprise NVMe all-flash arrays, and high-speed storage R&D testing environments, rigid backplane connections often face physical space constraints and connector wear from frequent mating cycles. To solve these challenges, we engineered the SFF-8639 (U.2/U.3) 68-Pin Male to Female High-Speed Extension Cable (Part No.: T1070E9682603-X).
Fully compliant with SFF-8639 specifications, this assembly provides a 1:1 full-pinout pass-through for high-speed differential pairs, sideband signals, and 12V/5V power delivery. Built with UL20744 32AWG silver-plated copper twinax wire and enclosed in high-density nylon braided sleeving, it maintains strict 85Ω differential impedance and low insertion loss—delivering reliable physical interconnectivity for flexible U.2/U.3 NVMe SSD placement and high-cycle production test benches.
