This 50-centimeter Ultraport Slimline SAS 4.0 breakout cable follows SFF SlimSAS industrial specifications, featuring one SFF-8654 8i 74Pin male host connector and two separate SFF-8611 OCuLink male target ports. It converts a single high-density SlimSAS x8 storage channel into dual independent OCuLink 4i interfaces, ideal for next-gen OCP open compute, cloud and high-density enterprise server storage expansion.
Constructed with high-quality shielded twinax conductors and precise impedance control, the cable effectively blocks electromagnetic interference and long-distance signal loss, maintaining full PCIe 4.0 bandwidth without thermal throttling. The slim flexible outer jacket saves internal chassis space and improves heat dissipation.
Each OCuLink connector comes with integrated locking latches to avoid loose connection failures caused by rack vibration, perfectly matching OCuLink HBA cards, NVMe backplanes and external OCuLink JBOD arrays. No driver installation required, widely used for multi-drive NVMe RAID deployment, server high-speed cache upgrade and mass data center storage array construction projects.
