Cabo Areca SlimSAS x8 STR SFF8654 para 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.
