PCIe Gen 4 Oculink 4i to U.2 Cable - 150cm

Technical Description

This cable provides a high-speed physical interconnect between an OCuLink 4i (SFF-8611) host connector—typically found on motherboards, HBAs, or servers—and a U.2 (SFF-8639) device connector used by enterprise and high-performance NVMe SSDs. It carries a native PCIe x4 signal path (4 lanes) rated for Gen 4 speeds, supporting up to 16 GT/s per lane (roughly 64 Gbps / 8 GB/s aggregate bidirectional throughput). At 150cm, it's designed for longer routing runs such as connecting a motherboard OCuLink port to a drive bay, hot-swap backplane, or external enclosure in a case where the SSD isn't mounted close to the host connector.

Top 10 Characteristics

1. PCIe Gen 4 certified — supports up to 16 GT/s per lane, backward-compatible with Gen 3/Gen 2 speeds
2. x4 lane configuration — full 4-lane PCIe signal path for maximum NVMe bandwidth
3. OCuLink 4i (SFF-8611) connector — compact host-side connector standard for internal PCIe routing
4. U.2 (SFF-8639) connector — industry-standard connector for enterprise/data-center NVMe SSDs
5. 150cm length — extended reach for flexible case routing, backplane connections, or rack-mount setups
6. High-quality shielded construction — typically uses twinaxial or shielded conductors to minimize signal loss/EMI at high frequencies
7. Low-latency, direct PCIe passthrough — no protocol conversion chip needed (native PCIe electrical signaling)
8. NVMe SSD compatibility — works with U.2 enterprise/data center drives (Intel, Samsung, Micron, etc.)
9. Hot-swap support — compatible with U.2 backplanes that allow drive hot-plugging (backplane-dependent)
10. Motherboard/HBA agnostic — works with any OCuLink 4i-equipped host port (consumer boards, workstation boards, HBAs/RAID cards)
