Scale fiber access without compromising service continuity. The UISP Fiber OLT XGS delivers 10 Gbps XGS-PON capacity across 8 ports, supporting up to 2,048 clients from a compact 1U rack-mount chassis. With 4 x 25G SFP28 uplink ports, it is built to move traffic efficiently into the aggregation layer while preserving room for growth. This model is designed for operators who need more than basic access hardware. AC/DC power module redundancy support helps maintain service during power events, while SNMP support fits into established network management workflows. The result is a platform suited to dense subscriber environments where uptime, port density, and uplink capacity directly affect operating margin. Compared with lower-capacity OLTs, the UISP Fiber OLT XGS is positioned for deployments that expect rapid subscriber expansion and higher per-site traffic demand. It gives infrastructure teams a practical way to extend fiber service at scale while keeping the footprint small and the architecture straightforward.
