Ubiquiti UACC-DAC-QSFP28-3M — 100G QSFP28 DAC, 3 m
100G / 40GQSFP283 mCopper
The Ubiquiti UACC-DAC-QSFP28-3M is a 3 m direct attach copper cable with a QSFP28 plug moulded onto each end, carrying 100G or 40G between two ports. It is the simplest way to join UniFi aggregation switches, gateways and servers that sit in the same rack or the next one, with no optics to buy and nothing to clean. In practice, a DAC is the cheapest way to join two switches that sit next to each other.
Compatibility — check before buying:
It fits QSFP28 and QSFP+ ports only — not SFP+ or SFP28 ports — and it is a straight QSFP28-to-QSFP28 cable, not a breakout to four SFP ports. Both ends must run the same speed. At 3 m the cable is 8.9 mm thick with a 47 mm minimum bend radius, so plan cable management in tight racks. Not sure? Send us your device model and the cable run and we check it before you order.
Best For
✓ 100G links between UniFi switches in one rack
✓ Aggregation to core switch links
✓ Server-to-switch 100G links
✓ 40G links on QSFP+ ports
✓ Adjacent racks up to 3 m
✓ Replacing optics on short runs
Key Features
100G at the lowest cost
For links up to 3 m a DAC replaces two optics and a fibre, and uses less power.
Cable and optics in one
A direct attach cable has the plugs moulded onto the cable, so there is nothing to clean, pair or buy separately.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.
Plan both ends together
A link only comes up when both ends use the same standard, speed and media. Order the far-end module, the cable and any spares in one go and the link works on day one.

Frequently Asked Questions
Singular Expert Insight
We fit the 3 m UACC-DAC-QSFP28 between UniFi aggregation switches and servers in the same or the next rack. Measure the route including the cable manager; for shorter hops the 0.5 m and 1 m versions keep the rack tidy, and for runs beyond 3 m use optics or an AOC. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 100G or 40G link of up to 3 m between QSFP28/QSFP+ ports.
Skip it if
The run is longer than 3 m, the ports are SFP+/SFP28, or you need a breakout cable.
