Areca Cable SlimSAS x8 STR SFF8654 a 2x OCuLink x4 SFF8611

Unlock the full potential of PCIe Gen4 with this Areca internal data cable, engineered to deliver an astonishing 16 GT/s per lane across eight host lanes split into two x4 OCuLink connections. Built for high-performance NVMe storage arrays, it ensures your data moves at the speed of your SSDs.

Overview

The Areca SlimSAS x8 (SFF-8654) to dual OCuLink x4 (SFF-8611) cable is a precision-engineered interconnect for modern servers and workstations. It converts a single SlimSAS x8 host port into two independent OCuLink x4 channels, enabling direct attachment of up to two NVMe SSDs or other PCIe devices. With a straight host connector orientation, it fits neatly into tight spaces while maintaining signal integrity.

What stands out

• Supports PCIe Gen4 speeds up to 16 GT/s per lane for maximum throughput.
• Dual OCuLink x4 outputs allow connection of two NVMe drives from one host port.
• Premium materials: tinned copper conductors, foamed polyethylene insulation, and gold-plated contacts ensure reliable, long-lasting performance.
• 85 Ohm differential impedance precisely tuned for high-speed differential signaling.
• Wide operating temperature range from -20°C to 85°C for demanding environments.
• Compliant with RoHS and REACH, meeting strict environmental standards.
