Fervit MiniSASHD 4X to OCuLink 4X Cable SFF8643 36Pin to SFF8611 42Pin 57CM

SKU CH-TFNB-SZJCB

Connects MiniSAS HD 4X to OCuLink 4X for NVMe SSDs, RAID controllers and storage arrays with 57CM server-grade shielded cable

  • Connects MiniSASHD 4X to OCuLink 4X for server storage
  • Matches part CBLSAST0929 for direct hardware compatibility
  • 57CM length enables tidy routing in standard chassis
  • 36-pin to 42-pin layout supports NVMe SSDs and RAID arrays
  • Anti-interference design reduces signal loss and crosstalk

Server Storage Connectivity

The Fervit MiniSASHD 4X to OCuLink 4X cable bridges SFF8643 36Pin and SFF8611 42Pin interfaces for enterprise server storage deployments. It targets system integrators and administrators who need to link NVMe SSDs or RAID controllers across dissimilar backplane and controller ports.

Interface Conversion Limits

Crossinterface conversion between MiniSASHD and OCuLink 4X lanes enables highbandwidth data paths, but the cable does not translate protocol differences between SATA and NVMe endpoints. Signal integrity relies on the host controller and backplane supporting the same electrical standard across the SFF8643 to SFF8611 link.

Replaces Custom Harnesses

This 57CM assembly replaces custom length harnesses and mismatched adapter chains that clutter standard size server chassis. The jump is worth it when a direct SFF8643 to SFF8611 connection eliminates signal loss points and reduces cable management complexity for part number CBLSAST0929 compatibility.

Questions about this item

What length should I choose for a standard server chassis?

The 57CM cable is optimised for neat internal routing in standard‑size server chassis.

What does the 4X lane count mean once the cable is installed?

Four lanes carry PCIe traffic between the MiniSASHD and OCuLink ends, giving NVMe SSDs and RAID controllers full‑speed bandwidth.

How do the SFF8643 and SFF8611 connectors differ in practice?

SFF8643 is a 36‑pin MiniSASHD 4X plug; SFF8611 is a 42‑pin OCuLink 4X plug. They connect different enterprise backplanes and controllers.
