Slimline SAS SFF8654 8i cable splitting to dual SFF8654 4i connectors, .8m length

SMUGDESK

SMUGDESK Slimline SAS SFF8654 8i to Dual SFF8654 4i Cable 0.8M

SKU CH-TCB9-070SR

Splits one SFF8654 8i port into two SFF8654 4i connections with anti-misplug design, 10 ohm impedance and 12 Gbps NVMe bandwidth over .8 m

  • One cable splits an 8i port into dual 4i ports for multi‑drive expansion
  • Anti‑misplug design stops reverse insertion and protects hardware
  • 10 ohm impedance matching keeps signals clean at 12 Gbps
  • 32 AWG low‑loss copper delivers reliable 12 Gbps throughput for NVMe SSDs
  • 8 m length fits tight rack servers and compact workstations

Slimline SAS SFF8654 Breakout Cable

This cable splits a single SFF8654 8i port into two independent SFF8654 4i interfaces for multi-drive expansion. It is designed for server and workstation builders who need to connect multiple NVMe SSDs or RAID controllers from one controller port. The compact 0.8 meter length supports tidy routing inside high-density chassis.

Thermals Noise and Power Draw

As a passive copper cable, it generates no heat and requires no external power supply. Operation is completely silent with zero fan noise or active cooling requirements. The 32AWG low-loss conductors minimise signal attenuation while drawing negligible power from the connected controller.

12Gbps Bandwidth with 10ohm Impedance

Strict 10ohm impedance matching and heavy-duty shielding maintain stable 12Gbps signal integrity for enterprise-grade storage systems. The built-in anti-misplug design prevents reverse insertion that could damage hardware during installation. This cable is not suited for links requiring longer reach or different connector form factors.

Highlights

Questions about this item

How do I install the SMUGDESK Slimline SAS SFF8654 8i to Dual SFF8654 4i Cable and what is the common mistake?

Align the built-in anti-misplug key on each SFF8654 4i connector with the port notch before pushing straight in; the step people get wrong is forcing the plug upside-down, which the key prevents but can damage pins if ignored.

What maintenance or replacement will this 0.8M 32AWG cable need later?

No scheduled maintenance is required; inspect the 10ohm impedance-matched conductors and heavy-duty shielding during routine server checks and replace the cable only if the latch tabs break or signal errors appear on the 12Gbps SAS links.

What limit shows up first under sustained 12Gbps NVMe RAID workloads?

The 0.8metre length and 32AWG gauge set the practical reach; in dense chassis the fixed 10ohm impedance and connector latch clearance become the limiting factors before the copper itself degrades.
