SKU CH-W6WP-BDTXK MPN UC-DAC-SFP28

Passive SFP28 direct-attach copper cable supports 25Gbps over .5m with 4.5mm ultra-thin 30AWG construction

  • Passive design needs no power for simple deployment
  • SFP28 connectors deliver 25 Gbps throughput for high-speed links
  • Ultra-thin 4.5 mm diameter eases routing in dense racks
  • 30 AWG copper construction keeps the cable light and flexible
  • Half-metre length suits adjacent-port connections in switches and servers

Direct Attach Copper Cable SFP28 25Gbps

The UniFi UC-DAC-SFP28 is a passive Direct Attach Copper cable with male SFP28 connectors on both ends. It carries 25Gbps over a 0.5m link using ultra-thin 30AWG conductors with a 4.5mm outer diameter. The assembly requires no external power and is designed for short rack connections.

Suits adjacent SFP28 ports; not for longer runs

This cable fits deployments where two SFP28 ports sit side by side in the same rack or shelf. Builders needing reach beyond half a metre, or links that require active optics for signal conditioning, should select a different cable type.

0.5 metre length decides fit

The fixed 0.5 metre length is the single specification that determines whether this part matches the physical port spacing in your installation. Measure the exact connector-to-connector distance before ordering.

Questions about this item

Will the 0.5 m SFP28 DAC reach between adjacent rack-mounted switches with existing SFP28 ports?

Yes, the half-metre length suits side-by-side or neighbouring rack units and the male SFP28 connectors mate directly with standard SFP28 cages.

How can I confirm the link is running at 25 Gbps after I plug it in?

Check the switch port statistics or LED indicators — a negotiated 25 Gbps rate and clean error counters show the passive DAC is operating correctly.

Does the box include transceivers or only the cable with integrated SFP28 ends?

The cable has SFP28 connectors permanently attached at both ends, so no separate transceivers are required or supplied.
