SlimSAS SFF-8654 4i to U.2 SFF-8639 with 15P Power Cable

The SlimSAS SFF-8654 4i to U.2 SFF-8639 with 15P Power Cable is a high-performance integrated internal cable solution designed for modern data center and enterprise storage environments. This cable provides a complete interface conversion from the SlimSAS (SFF-8654) 4-lane host interface to a U.2 (SFF-8639) device connector while integrating essential 15-pin SATA power delivery. Engineered to support high-speed data transfer protocols including PCIe and SAS, this all-in-one solution enables reliable connectivity from modern host systems to U.2 NVMe SSDs, combining both data and power transmission in a single cable assembly for simplified deployment and optimized cabinet management.

Features

• Hybrid Interface Solution: Bridges the modern SlimSAS SFF-8654 4i interface with the U.2 SFF-8639 connector, providing seamless connectivity between current host systems and U.2 NVMe SSDs.
• Integrated Power and Data Delivery: The built-in 15-pin SATA power connector delivers necessary power to the connected U.2 SSD, eliminating the need for separate power cables and simplifying cabinet management.
• High-Speed Data Support: Supports high-speed data transfer protocols including PCIe 4.0 (16 GT/s) and SAS 4.0 (24 Gbps), ensuring efficient performance for enterprise storage applications.
• Enhanced Signal Integrity: Utilizes precision-engineered cables (typically 30-32 AWG) with multi-layer shielding to minimize signal degradation, crosstalk, and electromagnetic interference (EMI), maintaining data integrity.
• Space-Efficient Design: The SlimSAS connector's compact form factor (0.6mm pitch) allows for high-density configurations on host boards, while the integrated design reduces cable clutter.
• Secure Connection System: Features robust connectors with positive latching mechanisms to ensure stable connections in vibration-prone environments.
