UISP Fiber - Using the UFiber Instant SFP ONU (UF-Instant)

Readers will learn how to use and explore different use cases for deploying the UFiber Instant SFP ONU (UF-Instant). The UF-Instant is a high-performance GPON CPE in an SFP package that is compatible with various Ubiquiti devices that support SFP/SFP+ ports.

Using the UFiber Instant ONU

In this article, we have included a possible deployment scenarios where the UF-Instant is inserted into an EdgeRouter 4 (ER-4), allowing for GPON connectivity supported up to a maximum of 20km. The UF-Instant supports Bridge mode and multiple VLANs just like our other ONUs (UF-WIFI / UF-Nano / UF-LOCO).

ATTENTION: The UF-Instant only supports Bridge mode.

Deployment scenario where the UF-Instant is inserted into the SFP slot (Eth3) on the EdgeRouter 4 (ER-4). 

In the deployment scenario above, the UF-Instant ONU connects to the UFiber OLT 4 (UF-OLT-4) using several different UFiber accessories such as PLC splitters, SC/UPC to SC/APC feeder fiber cables and SC/APC to SC/APC drop fiber cables.

NOTE: See the Accessories article for more information on the different UFiber accessories.

The UF-Instant is inserted into the EdgeRouter 4 (ER-4) like any other SFP/SFP+ module, providing a Layer 2 connection to the device over which VLANs can optionally be tagged. After inserting the module into the device, verify that it has been successfully detected and negotiated at the appropriate speed/duplex values. The following UFiber help center articles have more information on setting up the UFiber GPON network:

See the Beginners Guide to EdgeRouter and the How to Configure an Interface articles for the EdgeRouter side of the configuration.
