The FAB‑G125X is a micro-sized, energy-efficient XPON ONU designed for high-performance FTTH single-user deployments. With a transmission capacity of 1.244 Gbps upstream / 2.488 Gbps downstream, this ONU ensures stable access to high-speed internet over GPON/EPON networks.
Equipped with 1× 10/100/1000 Mbps RJ45 port, the device supports bridge and router modes, with PPPoE, DHCP, and static IP configuration. Designed with a Type-C 5V power input, its ultra-low power consumption (<2.3 W) makes it ideal for cost-sensitive deployments requiring compact form factor and excellent thermal efficiency.
Built for advanced ISP infrastructure, the FAB‑G125X includes VLAN tagging and conversion, broadcast storm control, dynamic bandwidth allocation (DBA), port-based speed limitation, and priority classification. It supports IPv4/IPv6, remote management via OMCI, Telnet, HTTP, and EMS platforms, with full status, configuration, and alarm monitoring features.
