40cm PCIe 4.0 Ultraport Slimline SAS Splitter Cable, SFF-8654 8I 74Pin to Dual SFF-8654 4I 38Pin Server Internal Interconnect Cord for NVMe SSD Backplane Storage Controller Expansion

This 40-centimeter enterprise-grade Slimline SAS splitter cable follows PCIe 4.0 and SAS 4.0 industrial specifications, designed for internal high-density storage interconnection of rack servers, NAS arrays and high-performance workstations. One end adopts 74Pin SFF-8654 8I Ultraport Slimline SAS male connector, which splits the 8-lane bandwidth into two separate 4-lane channels via the cable body, outputting to two independent 38Pin SFF-8654 4I male connectors respectively, perfectly connecting a single storage controller port to two hard disk backplanes or NVMe U.3 SSD expansion modules.

Constructed with high-purity silver-plated copper conductors and full-wrap braided electromagnetic shielding sleeve, the cable effectively reduces signal attenuation, high-frequency interference and data bit errors under long-term heavy-load operation, fully meeting strict transmission requirements of high-speed NVMe storage systems. All terminals are equipped with built-in locking buckles and gold-plated contact pins, resisting oxidation, abrasion and accidental disconnection caused by cabinet vibration, greatly improving reliability in data center continuous running scenarios.

The compact 40cm reserved length simplifies internal chassis cable management, optimizes airflow layout and enhances overall heat dissipation efficiency of the server. Widely applied in enterprise storage backplane expansion, high-density disk cage wiring, AI computing host storage deployment, cloud server hardware integration and IT equipment maintenance upgrading, it is a professional dedicated internal splitter cable for system integrators and server engineers.
