    The GRG-4260u is an advanced GPON ONT router-gateway with 1 GPON WAN port, 4 Gigabit Ethernet LAN ports, 2 FXS ports, 1 USB2.0 Host and Wi-Fi. The Wi-Fi not only provides an 802.11n 2x2 2.4GHz Band which is backward compatible with 802.11g/b but also supports high performance 802.11ac with 3x3 design at 5GHz band. GRG-4260us provides powerful functions which telephone companies have applied on the xDSL CPE IAD device, and remote management utilities (such as TR-069) for network management and maintenance.
