Product Information
Full details
The Ubiquiti UACC-UPLINK-SFP28-0.3M is a high-speed direct attach cable designed for network administrators and home lab enthusiasts looking to establish robust, short-range connections between UniFi switches, gateways, and high-performance servers. Its primary benefit is the built-in auto link optimization, which allows it to negotiate seamlessly between 1G SFP, 10G SFP+, and 25G SFP28 standards. One notable caveat is the 0.3-meter length, which limits usage exclusively to devices located within the same rack or adjacent stackable units.

Extended Product Information
FAQs
Can I use this cable with non-Ubiquiti hardware?
While it uses standard SFP28 connectors, it is optimized specifically for the UniFi ecosystem and performance may vary or be unsupported on third-party hardware.
Does this cable require extra configuration?
No, the cable utilizes auto link optimization, allowing it to negotiate speeds automatically without manual intervention.
Is this a fiber optic or copper cable?
This is a passive direct attach copper cable, not fiber optic.
What is the maximum speed supported?
The cable supports data transfer rates up to 25 Gbit/s.
What should I do if the cable is too short for my rack?
If 0.3 meters is insufficient, you will need to source a longer DAC cable or utilize fiber optic transceivers with separate LC-to-LC patch cables.
Is the cable plenum-rated?
The jacket is made of Polyvinyl chloride (PVC). Please check your local building codes to ensure it meets your specific installation requirements.
Troubleshooting
Link not established
Check that the cable is fully seated in the port and verify that the switch port is enabled in the UniFi controller.
Intermittent connectivity
Inspect the cable for any signs of physical damage or sharp bends exceeding the 2cm radius limit.
Device not recognizing the cable
Ensure the firmware on your UniFi device is up to date, as newer firmware versions provide improved compatibility for SFP28 modules.
