Product Description

This SFF-8654 8i to SFF-8654 8i high-density connector cable is designed for next-generation high-speed storage and PCIe applications inside compact electronic systems. Both ends are equipped with Mini SAS HD male connectors using precision crimp terminals and secure latching shells, providing a reliable mating interface to host and backplane PCB headers.

The 30/32AWG copper twinax wire cable is engineered for an 85-ohm differential impedance, supporting clean digital signal transmission for SAS, NVMe, and other high-bandwidth protocols. Each pair is foil-shielded with an overall braided screen to minimize crosstalk and EMI in dense server and industrial control enclosures. A black PET braided sleeve improves abrasion resistance, airflow and cable management while keeping the harness flexible.

With full OEM/ODM customization capability, the assembly can be adapted to different pin-outs, lengths, labeling, or combined with auxiliary power and control lines, giving system integrators a complete high-speed interconnect solution.

Applications 

Internal connection between Mini SAS HD host ports and SAS-8087 backplanes in 1U/2U/4U rackmount servers

Expansion links in JBOD/JBOF enclosures, DAS/NAS devices and enterprise storage arrays

High-density RAID subsystems in data centers and GPU/AI servers where compact, shielded cables are required

Industrial computers and embedded systems using SAS-based SSD/HDD modules on customized PCB backplanes
