Ubiquiti UISP-FIBER-OLT-XGS Optical Line Terminal
Overview
The UISP-FIBER-OLT-XGS is an eight-port optical line terminal (OLT) designed as the central access point for fiber-to-the-home (FTTH) and fiber-to-the-business (FTTB) networks. Each of the eight ports delivers 10 Gbps XGS-PON bi-directional capacity, supporting up to 2,048 subscriber endpoints per unit. The device ships as a 1U rack-mount unit with four 25G SFP28 uplink ports and AC/DC power module redundancy support — the right choice when you need to aggregate hundreds of fiber subscribers into a single termination point without overwhelming your core network.
Compatibility
The UISP-FIBER-OLT-XGS integrates natively with Ubiquiti's UISP Fiber product family and UISP management platform. It functions as the carrier-grade access aggregation point for fiber-fed neighborhoods, metropolitan FTTH deployments, and regional ISP rollouts. The device supports XGS-PON technology, which is the standard passive optical network protocol for 10G fiber subscriber delivery. Compatible with UISP provisioning, monitoring, and service orchestration systems for centralized subscriber billing and performance metrics across fiber distribution terminals.
Installation Notes
The UISP-FIBER-OLT-XGS mounts in standard 19-inch telecom racks at 1U of vertical space. Gross weight is 11.7 lb, typical for rack-mount fiber aggregation hardware. The device accepts both AC and DC power inputs via redundant modules, allowing dual-feed configurations in NOC and data-center environments where power loss cannot be tolerated. Four 25G SFP28 uplink ports require compatible transceiver modules (sold separately) for core network backhaul — verify transceiver compatibility with your upstream aggregation switch or router before deployment. Eight subscriber ports terminate fiber runs from ONT devices; ensure all fiber patch cables meet XGS-PON standard specifications and loss budgets before splicing or terminating to avoid signal degradation.
