100cm PCIe 4.0 Slimline SAS to OCuLink Breakout Cable, SFF-8654 8i 74Pin Ultraport Slim SAS Male to Dual SFF-8611 OCuLink PCIe x4 Male Splitter Cable for Server External NVMe Storage & eGPU Expansion

This 100cm passive Ultraport Slimline SAS breakout cable follows SFF-TA-1016 industrial standards. It features one SFF-8654 8i 74Pin male SlimSAS host connector, which fans out to two separate SFF-8611 OCuLink male terminals. The cable converts a single PCIe x8 SlimSAS interface on server motherboards or RAID HBA adapters into two standalone PCIe x4 OCuLink signal paths, enabling simultaneous connection of dual external NVMe storage enclosures, OCuLink eGPU docks and portable high-speed drive modules.

Constructed with oxygen-free copper differential pairs with strict 85-ohm impedance matching and double aluminum foil composite shielding, the cable suppresses electromagnetic crosstalk and signal attenuation, delivering full unthrottled PCIe 4.0 bandwidth during prolonged high read-write tasks. All pins on SFF-8654 and dual SFF-8611 connectors adopt thick gold plating to cut contact resistance and resist oxidation after years of round-the-clock datacenter operation. Built-in snap latches secure every connector tightly to avoid signal dropouts caused by rack vibration or external device movement.

The slim flexible outer jacket enables tidy internal and external cable routing without obstructing chassis cooling airflow. Compatible with mainstream server hardware equipped with SFF-8654 SlimSAS ports, including Supermicro, Dell, HPE, Lenovo and Inspur. Driver-free plug-and-play design works perfectly with Windows Server, Linux and mainstream desktop operating systems. It is ideal for high-density external NVMe storage cluster construction, dual OCuLink eGPU expansion, AI workstation storage upgrades and cloud server external hardware modification.

Note: This cable transmits native PCIe signals only and is not compatible with SAS protocol storage devices.
