PCIe 4.0 Ultraport Slimline SAS Breakout Cable 100cm, SFF-8654 8i 74Pin Male to Dual SFF-8643 4i Mini SAS HD Splitter Cable for Server NVMe RAID Backplane Storage Expansion

This 100cm Ultraport Slimline SAS passive breakout cable follows official SFF-TA-1016 industrial specification, featuring one SFF-8654 8i 74Pin male host connector that splits to two separate SFF-8643 Mini SAS HD 4i male terminals. It converts a single PCIe x8 SlimSAS port on motherboard or HBA card into two standalone PCIe x4 signal paths, supporting simultaneous connection of two independent storage backplanes, NVMe SSD arrays or RAID modules.

Constructed with oxygen-free copper differential pairs with precise 85-ohm impedance control and dual-layer foil shielding, the cable eliminates crosstalk and electromagnetic interference, retaining full native PCIe 4.0 bandwidth without throttling during sustained high read-write workloads. All pins of SFF-8654 and dual SFF-8643 connectors adopt thick gold plating to lower contact resistance and resist long-term oxidation; integrated snap latches lock each connector tightly to avoid signal dropouts caused by cabinet vibration.

The 1-meter extended length provides sufficient wiring distance for large 2U/4U rack servers and full-tower workstations. Slim flat braided outer jacket enables tidy internal cable management and maintains unobstructed chassis cooling airflow. Widely compatible with mainstream server brands equipped with SFF-8654 SlimSAS interfaces, including Supermicro, Dell, HPE, Lenovo and Inspur.

Plug-and-play design requires no extra drivers, compatible with Windows Server, Linux and mainstream workstation operating systems. Ideal for high-density NVMe storage cluster deployment, dual backplane breakout upgrades, AI computing storage and cloud datacenter server hardware modification.
