Ubiquiti UF-OLT-4 Fiber OLT 4 Optical Line Terminal

Ubiquiti UF-OLT-4 Fiber OLT 4 Optical Line Terminal

The Ubiquiti UISP Fiber OLT 4 (UF-OLT-4) is a compact four-port GPON Optical Line Terminal designed for internet service providers and fibre network deployments. Supporting up to 512 registered ONUs/ONTs across four GPON ports, with up to 128 clients per port, it provides a scalable platform for delivering high-speed fibre connectivity. The UF-OLT-4 combines four GPON OLT SFP interfaces with a 10Gbps SFP+ uplink, dedicated out-of-band Ethernet management and an RJ45 serial console interface, while UISP integration provides convenient network administration and monitoring.

Please Note: The UF-OLT-4 provides four GPON OLT SFP interfaces, but compatible GPON OLT SFP optical modules are accessories and should not be assumed to be included unless specifically stated by the supplier. Ubiquiti lists its GPON OLT SFP modules separately. Actual maximum fibre distance and subscriber deployment depend on the optical modules, split ratio, optical loss budget and overall passive optical network design.
