PCIe 4.0 Slimline SAS Breakout Cable 40cm, SFF-8654 8i 74Pin Male to Dual SFF-8654 4i 38Pin Male Ultraport Splitter Cable for Server NVMe Storage Backplane

This 40cm Ultraport Slimline SAS breakout cable is built per SFF-TA-1016 specification, featuring one SFF-8654 8i 74Pin male host connector splitting into two separate SFF-8654 4i 38Pin male target connectors. It converts a single PCIe x8 SlimSAS host port into two standalone PCIe x4 signal channels, enabling simultaneous connection of two NVMe backplanes or drive modules from one motherboard/HBA SlimSAS interface.

Fully compatible with PCIe 4.0 and backward compatible with PCIe 3.0, the cable delivers maximum native bandwidth without throttling during heavy continuous read-write operations. Oxygen-free copper differential conductors with precise 85-ohm impedance matching and composite double foil shielding eliminate crosstalk and electromagnetic interference, guaranteeing error-free data transmission in round-the-clock enterprise server environments.

All contact pins on both 74Pin and 38Pin terminals are gold-plated to reduce contact resistance and resist long-term oxidation. Built-in snap locking latches firmly lock each connector to avoid signal dropouts caused by rack vibration. The slim flexible outer jacket supports tidy internal cable arrangement in high-density rack servers, tower workstations and compact NAS enclosures.

Wide hardware compatibility covers mainstream server brands with SFF-8654 SlimSAS ports, including Supermicro, Dell, HPE, Lenovo and Inspur. Perfect for NVMe storage array expansion, internal backplane breakout upgrades and high-performance computing storage clusters. No extra drivers required, compatible with Windows Server, Linux and workstation operating systems.
