Specifications

OCuLink SFF-8611 (Straight) to SlimSAS 4i SFF-8654 (Right Angle) — 50cm

Technical Description

Connector A (Host/Source): OCuLink SFF-8611, straight plug, 4-lane (4i) PCIe configuration
Connector B (Device/Target): SlimSAS SFF-8654, right-angle plug, 4-lane (4i) configuration

Signal type: PCIe 3.0/4.0 (and often backward-compatible to earlier generations depending on cable quality), supporting 4 lanes of high-speed serial data plus sideband signals (SMBus/JTAG/side-band per spec).

Cable length: 50cm (~19.7 in)

Typical use case: Connects a motherboard, HBA, or backplane with an OCuLink port to a device (SSD, GPU riser, expansion card, or backplane) using a SlimSAS port — common in NVMe storage setups, server backplanes, and PCIe expansion for U.2/U.3 drives.

Construction: Shielded twinaxial or coax pairs per differential lane, foil + braid shielding for EMI suppression, typically 30–32 AWG internal conductors with a durable outer jacket (often UL-rated, low-smoke or PVC depending on grade).

Bandwidth: Supports up to PCIe Gen4 speeds (~16 GT/s per lane) if built to spec — verify the specific SKU's rated generation, as OCuLink/SlimSAS cables vary between Gen3 and Gen4 builds.

Right-angle design: The SFF-8654 end is angled 90° to accommodate tight chassis clearances, backplane routing, or low-profile builds where a straight connector wouldn't fit.

Top 10 Characteristics

  1. 4-lane (4i) PCIe signal support — full x4 bandwidth in a single cable
  2. PCIe Gen3/Gen4 compatible — high-speed NVMe/SSD data transfer
  3. Right-angle SlimSAS connector — saves space in tight enclosures
  4. Straight OCuLink connector — flexible routing on the host side
  5. 50cm length — ideal for mid-tower cases, server chassis, and backplane connections
  6. Shielded construction — reduces EMI/crosstalk for signal integrity at high speeds
  7. Low-latency, low-loss design — critical for maintaining PCIe signal timing
  8. Durable connector latches — secure locking clips prevent accidental disconnection
  9. Broad compatibility — works with NVMe SSD backplanes, HBAs, GPU docks, and PCIe expansion systems
  10. Hot-swap/enterprise-grade reliability — commonly used in server and workstation storage builds
