UniFi – USW: Which SFP Modules Can be Used

The Ubiquiti UFiber modules are officially supported and compatible with all EdgeSwitch, EdgeRouter, UniFi Switch, UniFi Dream Machine Pro and UniFi Security Gateway models that have SFP or SFP+ ports. Multi-mode and single-mode SFP and SFP+ models are available, including single-mode BiDi models.

SKU (Model)1G (SFP)10G (SFP+)25G
UDC-1 (1m)UDC-2 (2m)UDC-3 (3m)* 
UC-DAC-SFP+ (0.5m)* 
UC-DAC-SFP28 (0.5m)  **

*Ports can be set manually to 1000mbps for compatibility between SFP+ and SFP ports. |  ***SFP28 to SFP28 (max data rate 25Gbps)

The list below includes third-party SFP/SFP+ transceivers that have been tested by community members. Please note that these should work, but we cannot assure that they will. Some modules will have multiple hardware revisions, and while one revision may work (i.e. 1.0), it’s possible that a newer revision (i.e. 1.1, 1.2, etc.) of the same module may not work.

We do, however, offer direct support for our own modules.

    • This is a 10g DAC that appears to link up at 1g when both ends are plugged into the two SFP slots of the ES-24-250W
    • I haven’t tested sending traffic over this cable, as I only have one ES-24-250W, and Juniper equipment wants to link up at 10g when using this DAC

The following SFP/SFP+ transceivers have been tested by community members, but may not work reliably. They are not recommended for use with UniFi switch.

  • TP-LINK┬áTL-SM311LS ** may not work on newer firmware, may also depend on module version
  • TP-LINK┬áTL-SM311LM ** may not work on newer firmware, may also depend on module version
