System Requirements

Before You Begin

Designing your first GPON deployment requires specific knowledge and planning. For information on GPON network design and installation, including important considerations and best practices, refer to:

For details on configuring UFiber devices for the first time to allow ONU LAN ports to provide connectivity, refer to: ubnt.link/UFiber-Initial-Configuration

Hardware Overview

PON Port

SC/APC GPON port supports WAN connections of 2.488 Gbps downstream and 1.244 Gbps upstream.

LAN (Ports 1 - 4)

RJ45 Ethernet LAN ports support 10/100/1000 Mbps connections. Port 1 also supports 24V Passive PoE to power the device.

Reset Button

The Reset button serves two functions for the UF-WIFI:

  • Restart Press and release the Reset button quickly. The three signal LEDs will flash amber.
  • Restore to Factory Default Settings Press and hold the Reset button for more than five seconds.

Power Port

The Power Adapter connects to this port to provide power.

Signal LEDs



Signal strength: low

≥ -28 dBm

Signal strength: good

≥ -25 dBm

Signal strength: strong

≥ -11 dBm

Signal strength: too low

< -28 dBm

Check the quality of the fiber connection, and calculate the total optical loss of the optical splitters.

Signal strength: too strong

≥ -8 dBm

Add an optical splitter, or add a 5 or 10 dB optical attenuator.

No signal

Check the fiber cables and connectors, and ensure that the OLT functions properly.

No authority

The UF-WIFI has not been authorized or cannot communicate with the OLT. Check passwords and OLT settings.

Connecting Fiber

WARNING: Never look directly into the ends of fiber or modules. The emitted light could cause damage to the eye.

WARNING: Until ready for use, keep modules and fiber patch cables covered using the included protective caps to ensure the connections stay clean.

WARNING: Do NOT connect the device directly to a UFiber GPON module (UF-GP-B+ or UF-GP-C+). Doing so will damage the device optics. Ensure that the device’s received signal level never exceeds -8 dBm. Use a UFiber PLC Splitter to add attenuation as needed.

Connecting Power


Note: 24V Passive PoE is required to power the device.

WARNING: The PoE switch must comply with the power specifications listed in the Specifications section of this Quick Start Guide.

Accessing the Configuration Interface

  1. Ensure that your computer (or other host system) is connected to the device.
  2. Configure the Ethernet adapter on your host system with a static IP address on the 192.168.1.x subnet.
  3. Launch your web browser. Type in the address field. Press enter (PC) or return (Mac).

  4. Enter ubnt in the Username and Password fields. Click Login.

Customize settings as needed. For more information, refer to the UFiber resources, which are available at: http://ubnt.link/UFiber-Support
