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

This 100cm passive Slimline SAS breakout cable complies with SFF-TA-1016 industry standards, built with one SFF-8654 8i 74Pin male Ultraport Slim SAS host connector that fans out to two separate SFF-8643 4i Mini SAS HD male terminals. It converts one PCIe x8 SlimSAS interface on server motherboards or RAID HBA cards into two independent x4 signal paths, allowing simultaneous connection of two storage backplanes, U.2 NVMe SSD arrays or multi-drive RAID modules.

Manufactured with oxygen-free copper differential conductors and precise 85-ohm impedance matching, paired with dual-layer aluminum foil shielding, the cable effectively suppresses crosstalk and electromagnetic interference, delivering full unthrottled PCIe 4.0 bandwidth under continuous high read-write workloads. All contact pins of SFF-8654 and dual SFF-8643 connectors feature thick gold plating to cut contact resistance and resist oxidation over years of round-the-clock running. Built-in snap latches firmly lock each connector to avoid unexpected signal disconnection caused by rack vibration.

The 1-meter long flexible cable meets long-distance wiring demands in 2U/4U rack servers and full-size tower workstations. Slim lightweight outer jacket supports neat internal cable routing without blocking chassis cooling airflow. Compatible with mainstream server hardware with SFF-8654 SlimSAS ports, including Supermicro, Dell, HPE, Lenovo and Inspur.

Driver-free plug-and-play design works seamlessly with Windows Server, Linux and regular workstation operating systems. Perfect for high-density NVMe storage cluster setup, dual backplane expansion upgrades, AI high-performance computing storage and cloud datacenter server hardware replacement.
