4-port GPON OLT for ISPs

The Ubiquiti UF-OLT-4 is a managed rackmount Optical Line Terminal built for internet and telecom providers deploying GPON fibre networks. It delivers up to 2.488 Gbps downstream and 1.244 Gbps upstream to support Triple Play services. The unit is managed through the included UNMS controller for simplified configuration.

Check rack space and power input

Verify that a standard 19-inch rack can accommodate the 299.80 x 258.95 x 42.55 mm chassis and the 2.13 kg weight with brackets fitted. Confirm the site supply matches the 100240VAC 5060 Hz universal input before installation. Ensure SFP and SFP+ transceivers are sourced separately as none are included.

UNMS controller removes licence fees

The bundled UNMS controller provides a graphical interface that replaces command-line configuration and eliminates recurring support licence costs. It enables central management of up to 512 ONUs across the three GPON ports at 128 clients each. The single SFP+ uplink handles aggregated traffic from all connected endpoints.

Questions about this item

Does the UF-OLT-4 ship with the GPON SFP modules and SFP+ transceiver, or must they be purchased separately?

The unit provides four GPON SFP ports and one 1G/10G SFP+ port; the SFP and SFP+ transceivers are not included and must be sourced separately.

How do I decide between using one, two, three or all four GPON ports for my deployment?

Each GPON port supports up to 128 ONUs, so the total 512-client capacity scales linearly with the number of ports you populate — activate only the ports your subscriber count requires.

What do the 2.488 Gbps downstream and 1.244 Gbps upstream rates mean for actual subscriber throughput?

Those are the GPON line-rate limits shared across the 128 ONUs on a single PON port; real-world per-user speeds depend on the split ratio, traffic mix and QoS policies you configure in UNMS.
