PCIe 4.0 SFF-8654 74Pin 8i Slimline SAS Breakout Cable 50cm, Ultraport Slim SAS 8i to Dual SFF-8643 4i Mini SAS HD Splitter Cable for Server Storage Backplane

This 50cm Slimline SAS breakout cable features a single 74Pin SFF-8654 Ultraport Slim SAS 8i male connector that splits to two separate SFF-8643 Mini SAS HD 4i ports, following official SFF-TA-1016 industry specification for internal server storage expansion. It converts one 8-lane SlimSAS host interface into dual independent 4-lane Mini SAS HD signal groups, allowing simultaneous connection of two storage backplanes from one motherboard or HBA SlimSAS port.

Fully compatible with PCIe 4.0 specification, the cable maintains excellent signal integrity under sustained heavy I/O workloads. Impedance-matched pure copper differential pairs and double aluminum foil composite shielding effectively isolate electromagnetic interference to avoid data packet loss and transmission errors during round-the-clock server running. All contact pins on SFF-8654 and dual SFF-8643 terminals are gold-plated to boost electrical conductivity and resist long-term oxidation; built-in snap latches lock connectors tightly to prevent signal interruption caused by rack vibration.

The compact 50-centimeter length balances wiring flexibility and bandwidth stability, perfect for high-density rack servers, tower workstations and compact NAS enclosures. Widely compatible with mainstream server motherboards and RAID adapters equipped with SFF-8654 SlimSAS ports, including Supermicro, Dell, HPE, Lenovo and Inspur hardware. Backward compatible with PCIe 3.0 storage devices, ideal for NVMe SSD array deployment, internal storage breakout upgrades and enterprise computing storage cluster construction. The flexible outer jacket supports tidy internal cable management without obstructing chassis cooling airflow.
