Black round cable with MCIO 8i connector splitting to dual SFF8654 4i ends

SMUGDESK

SMUGDESK Gen5 MCIO 8X Slimline SAS 8i to Dual SFF8654 4i Cable .8m 24Gbps 85Ohm

SKU CH-1BYW-KSY90

Converts a single MCIO 8X Slimline SAS 8i port into two SFF8654 4i ports for 24Gbps NVMe storage expansion with 85Ohm impedance

  • Converts MCIO 8X to dual SFF8654 4i ports
  • 85 Ohm impedance enables 24 Gbps stable throughput
  • PCIe 5.0 compliant for NVMe and RAID arrays
  • .8 m length fits tidy internal server routing
  • Heavy shielding cuts crosstalk for reliable operation

Server Storage Expansion

This PCIe Gen5 interconnect cable converts a single MCIO 8X Slimline SAS 8i port into two independent SFF8654 4i ports. It enables highdensity NVMe storage expansion inside rackmount servers and workstations. The design targets administrators building multichannel enterprise arrays.

Thermals and Signal Integrity

Strict 85Ohm impedancematched conductors deliver ultralowloss 24Gbps signal transmission with minimal attenuation. Precisionengineered shielding minimizes crosstalk for reliable longterm operation. The fully PCIe 5.0 compliant construction ensures stable highspeed data transfer under sustained server workloads.

Upgrade Path and Limits

This cable replaces older lowerbandwidth interconnects when moving to 24Gbps SAS or NVMe backplanes. The jump is worth it for deployments requiring Gen5 throughput density. It does not suit builds needing longer reach than .8m or connectivity beyond dual 4i breakout.

Questions about this item

How do I connect the MCIO 8X Slimline SAS 8i end and the dual SFF8654 4i ends inside a server?

Insert the single MCIO 8X connector into the motherboard or controller port until the latch clicks, then plug each SFF8654 4i connector into its matching backplane or drive bay; the .8m length is sized for standard internal routing so avoid sharp bends that could stress the 85Ohm impedance-controlled conductors.

What upkeep does this cable require after installation?

No scheduled maintenance is needed; inspect the connectors and shielding only if you reseat hardware, and replace the cable if the latch mechanism wears or the heavy-duty anti-interference shielding shows physical damage.

What performance limit appears first during sustained 24Gbps transfers?

The cable is built to PCIe 5.0 compliance with strict 85Ohm impedance matching, so the practical ceiling under continuous load is the 24Gbps signal rate the conductors and shielding are engineered to sustain without attenuation.
