Ubiquiti U-Fiber 4-Port GPON Optical Line Terminal OLT [UF-OLT-4]

The Ubiquiti U-Fiber 4 Optical Line Terminal (OLT) offers internet and telecom service providers a cost‑effective fiber optic delivery system for Triple Play Services (data, voice, IPTV/VoD) with speeds of up to 2.488Gbps downstream and 1.244Gbps upstream. The Ubiquiti U-Fiber 4 OLT also boasts flexible layer 2/3 management features and one 1G/10G SFP+ Ethernet port.

The Ubiquiti UFiber network is intelligently managed using the included UISP application. Ubiquiti UFiber devices consist of either the UFiber OLT or OLT-4 (deployed at the provider premises) and the UFiber Nano G, loco, or UF-WiFi clients, which function as ONU CPEs (Customer Premises Equipment).
