Oculink 4i Angled Connector to 4 X SATA 7 Pin Cable - 400mm

OCuLink 4i (SFF-8611) Angled Connector to 4x SATA 7-Pin Breakout Cable – 400mm

Technical Description

This cable is a signal breakout adapter that converts a single OCuLink 4i (SFF-8611) connector into four independent SATA 7-pin data connectors. It is designed to let a single OCuLink port on a motherboard, HBA (Host Bus Adapter), or RAID controller distribute PCIe/SATA lane signaling out to four separate SATA drives (HDDs or SSDs) using standard SATA data cabling at the drive end.

• Host connector: OCuLink 4i (SFF-8611), right-angled form factor for low-profile clearance in tight case builds
• Device connectors: 4x SATA 7-pin (data only, not power)
• Cable length: 400mm (~15.7 inches)
• Lane configuration: Each OCuLink 4i port carries 4 lanes; this breakout splits those into 4 discrete single-lane SATA data paths
• Signal type: SATA III (6 Gbps) compliant per channel
• Shielding: Typically foil + braid shielded twisted-pair construction to reduce crosstalk/EMI at high data rates
• Connector orientation: Angled OCuLink head reduces strain and vertical clearance requirements near backplanes or crowded chassis
• Compatibility: Requires a host with a native OCuLink port wired for SATA breakout mode (common on server motherboards, storage backplanes, and some enterprise HBAs) — not universally compatible with all OCuLink ports, some of which are PCIe-only

Top 10 Characteristics

1. OCuLink 4i (SFF-8611) interface for high-density, high-speed connectivity from a single compact port
2. 1-to-4 SATA breakout design, replacing four discrete data cables with one consolidated run
3. Right-angle connector head for improved routing in space-constrained server/NAS chassis
4. 400mm length, suited for mid-tower to full-tower cases and 2U/3U server backplane distances
5. SATA III (6 Gbps) per-channel bandwidth support
6. Shielded cable construction to maintain signal integrity at high transfer speeds
7. Data-only design — SATA power must be supplied separately via a standard SATA power cable/PSU
8. Server/storage-grade application, commonly used in NAS units, RAID arrays, and hot-swap backplanes
9. Reduced cable clutter compared to running four individual SATA data cables from the motherboard
10. Passive cable (no signal conversion chipset) — relies on the host port's native OCuLink-to-SATA lane mapping
