The vSOL V2804-4GL-PSE is a high-performance XPON ONU designed for fiber optic broadband access networks. It supports GPON and EPON standards in dual mode, ensuring seamless integration with existing infrastructure. The device provides connectivity over a single fiber optic line up to 20 km and offers four Gigabit Ethernet ports on the subscriber side. All ports support the IEEE 802.3af/at PoE+ standard, delivering data and power over a single cable. The standout technical feature is that all four Gigabit Ethernet ports are PoE+ enabled, allowing direct powering of end devices such as IP cameras, access points, or VoIP phones without requiring a separate power source. With an optical receiver sensitivity of -27 dBm and transmission power between 0 and +4 dBm, it ensures stable fiber connections even under challenging line conditions. Its compact metal casing (205x125x28 mm) and wide operating temperature range (-10°C to +55°C) make it suitable for both office and industrial environments. This ONU is ideal for security camera systems and wireless network infrastructures. Installed in an apartment building entrance or office cabinet, the V2804-4GL-PSE can receive the fiber line and simultaneously power and connect up to four PoE-enabled IP cameras or WiFi access points. This eliminates the need for a separate PoE switch, reducing installation costs and cable clutter. For operators, it offers remote monitoring and configuration convenience through OMCI and OAM protocols allowing centralized management.
