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. Key Features 4-Port GPON OLT: Provides four GPON OLT SFP interfaces for building and managing fibre access networks. Up to 512 Clients: Supports up to 512 registered ONUs/ONTs, with up to 128 clients per GPON port. 10Gbps SFP+ Uplink: Dedicated SFP+ interface provides high-speed uplink connectivity. GPON Performance: Provides a nominal 2.488Gbps downstream and 1.244Gbps upstream optical interface bit rate. 20km Physical Reach: Supports fibre links with a physical reach of up to 20km, subject to optical network design. OLT & Layer 2 Switch: Operates as a GPON OLT core and Layer 2 Ethernet switch. 4062 VLANs: Extensive VLAN support enables network segmentation across large subscriber deployments. Advanced QoS: Supports eight priority queues per user port and traffic classification for effective bandwidth and service management. Dedicated Management: Includes an Ethernet out-of-band management interface and RJ45 serial console port. UISP Integration: Supports management through the Ubiquiti UISP ecosystem and UISP mobile application. Flexible Power: Supports universal 100-240V AC input as well as compatible 16-25V DC input.

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. The Ubiquiti UISP Fiber OLT 4 (UF-OLT-4) provides a compact GPON access platform for service-provider fibre deployments, combining four GPON interfaces, support for up to 512 registered ONUs/ONTs, a 10Gbps SFP+ uplink, Layer 2 switching, extensive VLAN and QoS capabilities and integrated UISP management.
