This industrial-grade active OCuLink storage cable strictly complies with PCIe 4.0 and SFF-9402 OCuLink industry standards, equipped with built-in signal retimer circuits to compensate signal loss, delivering consistent high-speed performance at full 100cm length that passive cables cannot support.
It converts one 8-lane SFF-8611 OCuLink host port to two separate SFF-8643 Mini SAS HD 4x interfaces, supporting simultaneous connection of two NVMe or SAS SSD backplanes. Each lane runs up to 16GT/s PCIe 4.0 bandwidth and maintains full backward compatibility with PCIe 3.0 hardware, ideal for RAID storage, high-performance computing, AI workstations and data center all-flash servers.
Double-layer aluminum foil + braided shielding structure effectively suppresses electromagnetic crosstalk in crowded cabinet environments. Compact slim cable body reduces internal wiring clutter and optimizes heat dissipation efficiency. All connectors adopt thick gold plating and auto-lock latches to guarantee stable plug-in connection under long-term continuous operation.
Compatible with mainstream server brands including Supermicro, Dell, HPE, Lenovo and ASUS. Plug-and-play design without extra driver installation, supporting Windows, Linux and enterprise NAS operating systems. Perfect for OCuLink controller card to SFF-8643 backplane interconnection, video editing storage expansion and multi-drive JBOD array deployment.
