Slimline SFF8654 8i cable splitting to dual SFF8639 U.2 with 15Pin power, .8m length

SMUGDESK

SMUGDESK SFF8654 8i to Dual SFF8639 U.2 15Pin Power Cable .8m

SKU CH-WTQC-QMTTH

Breakout cable converts a single SFF8654 8i Slimline port into dual SFF8639 U.2 NVMe interfaces with integrated 15pin power for 24Gbps enterprise storage expansion

  • Converts one SFF8654 8i port to dual SFF8639 U.2 drives
  • 15pin power integration merges data and power for cleaner server wiring
  • 24Gbps bandwidth supports highspeed NVMe SSDs and RAID arrays
  • 85ohm copper wiring reduces signal loss and EMI interference
  • .8m length fits tight routing in compact rackmount servers

Breakout Cable for Multi-Drive Expansion

This SMUGDESK breakout cable converts a single SFF8654 8i Slimline port into dual SFF8639 U.2 NVMe interfaces. It enables multidrive expansion for enterprise storage upgrades and highcapacity NAS systems. The design targets server administrators who need to connect multiple U.2 solidstate drives from one controller port. It is not for builders who require a single drive connection or lack a compatible Slimline host interface.

Signal Integrity and Power Delivery

Precisionmatched 85ohm copper conductors minimise signal attenuation, crosstalk and EMI interference during operation. The cable supports stable 24Gbps highbandwidth transmission for demanding storage arrays and RAID controllers. Integrated 15pin power connectors combine data and power delivery in one assembly. This reduces the number of separate power cables required inside the chassis.

Internal Routing and Build Quality

The .8metre length is optimised for neat internal routing in compact rackmount servers and highdensity workstations. Allinone datapluspower construction streamlines chassis wiring and simplifies cable management. Durable connectors ensure reliable mating cycles for missioncritical data center deployments. The fixed dual U.2 breakout does not suit installations needing variable port spacing or single drive connectivity.

Questions about this item

How do I connect the SFF8654 8i cable to the server backplane without bending the 85ohm copper wires?

Route the .8m cable along the chassis guides, plug the single SFF8654 8i end into the controller port, then attach each SFF8639 U.2 connector with its 15pin power lead to the drive bays, avoiding sharp bends that could deform the impedance-matched conductors.

What part of the cable will need replacement first if the 15pin power pins loosen from repeated drive swaps?

The integrated 15pin power connectors on each SFF8639 U.2 branch are the wear point; if pins spread or lose tension, the entire breakout assembly must be replaced because the power and data lines are moulded as one unit.

At what sustained throughput does the 24Gbps link hit its thermal limit inside a packed 1U rack?

The 85ohm copper construction is rated for continuous 24Gbps operation; the practical limit in a dense 1U enclosure is airflow around the cable bundle, not the interconnect itself, so maintain clear routing paths to prevent heat buildup.
