Ubiquiti UF-OLT-4 - 4-Port GPON OLT, 512 ONUs, 2.488 Gbps Downstream

Ubiquiti UF-OLT-4 – 4-Port GPON Optical Line Terminal

The Ubiquiti UF-OLT-4 is a 4-port GPON Optical Line Terminal for fiber access networks. It supports up to 512 concurrent ONU clients (128 per GPON port) at fiber distances up to 20 km, and delivers 2.488 Gbps downstream and 1.244 Gbps upstream per port. The unit runs as both a GPON OLT core and a Layer 2 Ethernet switch, with universal AC input (100–240VAC, 50/60 Hz) and an optional 24VDC secondary power input.

Management runs through UNMS (Ubiquiti Network Management System), a graphical controller that centralizes configuration and monitoring across multiple sites and ONU clients. UNMS is included at no additional licensing cost and installs on Linux.
