Ubiquiti SFP28 Direct Attach Cable
Ubiquiti 25G Direct Attach Cable (SFP28 to SFP28)
The Ubiquiti 25G Direct Attach Cable is a copper cable with an SFP28 connector at each end, for linking two ports at up to 25 Gbps without separate optical modules. Ubiquiti lists supported data rates of 25 / 10 / 1 Gbps and compatibility with SFP28, SFP+ and SFP interfaces. It is sold as a single unit in three lengths - 0.5 m, 1 m and 3 m - for short runs in the same rack or the next one.
Quick Glance
Key Features
25 Gbps over SFP28, with 10 and 1 Gbps support
Ubiquiti gives the cable a 25 Gbps max data rate and lists supported data rates of 25 / 10 / 1 Gbps. It has an SFP28 connector at both ends and is compatible with SFP28, SFP+ and SFP interfaces.
Copper cable with connectors built on
The SFP28 connectors are part of the cable, so a link needs no separate SFP28 modules and no fibre patch lead. Ubiquiti lists the wire as copper, with a black PVC jacket.
Three lengths for in-rack cabling
Choose 0.5 m (1.6 ft), 1 m (3.3 ft) or 3 m (9.8 ft). The jacket is 4.5 mm across on the 0.5 m and 1 m cables, with a minimum bend radius of 24 mm; the 3 m cable is 5.6 mm across, with a 31 mm minimum bend radius.
Detailed Specifications
Specifications are from Ubiquiti's technical specifications page and official store listing for the 25G Direct Attach Cable. Ubiquiti does not publish a weight for this cable.
Need-to-Know
One cable, three lengths. The 0.5 m and 1 m cables share the same jacket; the 3 m cable has a thicker jacket and a larger minimum bend radius.
- A direct attach cable replaces two modules and a patch lead: plug one end into each port. Both ports must be SFP28, SFP+ or SFP cages, not standard copper Ethernet sockets.
- Ubiquiti's spec gives the data rates as 25 Gbps, 10 Gbps and 1 Gbps. A link runs at a rate both connected ports support.
- Keep bends no tighter than Ubiquiti's minimum bend radius: 24 mm for the 0.5 m and 1 m cables, 31 mm for the 3 m cable.
- Each part number is one cable (Ubiquiti's pack option is Single Unit). Ubiquiti does not publish a weight for this cable.
| Part Number | Length | Jacket Outer Diameter | Minimum Bend Radius |
|---|---|---|---|
| UACC-DAC-SFP28-0.5M | 0.5 m (1.6 ft) | 4.5 mm (0.18") | 24 mm (0.94") |
| UACC-DAC-SFP28-1M | 1 m (3.3 ft) | 4.5 mm (0.18") | 24 mm (0.94") |
| UACC-DAC-SFP28-3M | 3 m (9.8 ft) | 5.6 mm (0.22") | 31 mm (1.22") |
Every length supports 25, 10 and 1 Gbps and is sold as a single unit.

Customer Benefits
- One cable instead of two SFP28 modules and a fibre patch lead for each short link.
- Three lengths, so the run fits the rack without excess cable to coil.
- Runs at 25, 10 or 1 Gbps and works with SFP28, SFP+ and SFP ports, per Ubiquiti.
- Supplied with a VAT invoice for business purchasing.

Frequently Asked Questions
Ubiquiti lists supported data rates of 25 Gbps, 10 Gbps and 1 Gbps, with a 25 Gbps max data rate. The cable has an SFP28 connector at each end, and Ubiquiti states it is compatible with SFP28, SFP+ and SFP interfaces.
The cable comes in 0.5 m (UACC-DAC-SFP28-0.5M), 1 m (UACC-DAC-SFP28-1M) and 3 m (UACC-DAC-SFP28-3M). The 0.5 m and 1 m lengths suit connections within one rack; the 3 m length reaches further, for example to an adjacent rack. Measure the route including bends, keeping to the minimum bend radius.
No. The SFP28 connectors are part of the cable, so it plugs straight into an SFP28, SFP+ or SFP port at each end. Ubiquiti lists the wire as copper.
The connectors, data rates, PVC jacket and black colour are the same. The 3 m cable has a thicker jacket (5.6 mm against 4.5 mm) and a larger minimum bend radius (31 mm against 24 mm) than the 0.5 m and 1 m cables.
