Slimline SAS 8i cable splitting to dual SFF8654 4i connectors, 0.8M length

Fervit

Fervit MCIO 8X Slimline SAS 8i to Dual SFF8654 4i Cable 0.8M

SKU CH-WAA6-2J83E

Connects an MCIO 8i port to two SFF8654 4i ports for 24Gbps NVMe storage expansion in servers

  • Enables multichannel high-density storage expansion with PCIe Gen5 MCIO 8X breakout to dual SFF8654 4i ports
  • Delivers ultralow-loss 24Gbps stable high-speed signal transmission via strict 85 Ohm impedance-matched wire
  • Supports tidy internal routing in rackmount servers and workstations with optimized 0.8M length
  • Ensures compatibility with NVMe SSDs and RAID controllers through full PCIe 5.0 compliance
  • Provides reliable long-term high-performance operation with precision-engineered shielding minimizing crosstalk

PCIe Gen5 MCIO 8X Breakout Cable

This 0.8 metre cable converts a single PCIe Gen5 MCIO 8X (8i) connector into two independent SFF8654 4i ports. It supports multichannel, high-density storage expansion in rackmount servers, NVMe backplanes and workstations. The assembly is fully PCIe 5.0 compliant for use with NVMe SSDs and RAID controllers.

Suited For Dense Server Storage

Builders expanding NVMe capacity in 1U or 2U chassis where a single MCIO uplink must feed two backplane ports will find the dual SFF8654 layout efficient. Buyers needing longer reach for full-height tower cases or external JBOD enclosures should look elsewhere, as the fixed 0.8 metre length limits routing flexibility.

Straightforward Internal Routing

The slim profile and matched 85 Ohm impedance allow clean installation through tight server mid-planes without sharp bends. Care is required to seat each high-density SFF8654 latch fully; incomplete insertion is the most common cause of link errors at 24 Gbps.

Questions about this item

What host interface is required for this MCIO 8X cable to operate at PCIe 5.0 speeds?

A PCIe Gen5 MCIO 8i connector on the motherboard or RAID controller is required for full 24Gbps throughput.

Does the 85 Ohm impedance match standard SAS signalling for legacy drive shelves?

The cable uses 85 Ohm impedance-matched wire tuned for PCIe 5.0 signalling, not traditional SAS voltage levels.

How can I verify the link is running at the rated 24Gbps after installation?

Check the controller BIOS or OS tool for a PCIe 5.0 x8 link width and 24 GT/s speed on each SFF8654 4i port.
