EPON ONU 4GE PORTS GDONU100-4GE

Overview    GDONU100-4GE is an ONU device designed by Lootom based on mixing and multi-service network. This series of products follow the international standard IEEE 802.3 ah, the communications industry standard of China (YD/T 1475-2006), and the EPON equipment technical requirements of China Telecom. It possesses good interoperability and maneuverability and it can realize interconnection with the mainstream OLT equipment manufacturers. Features         ● By using point to multipoint network topology, it can effectively collect scattered ethernet business users and convergence, fast ethernet interface on the user side to provide a standard RJ45 to smooth interconnection with the existing network.
        ● Dynamic bandwidth allocation mechanism ensures that all users can more reasonably share 1 Gbps bandwidth and realizing the reliable quality of service (QOS) and ensuring different business service quality in the same network.
        ● It supports IGMP multicast and makes good use of broadband.
        ● It supports ports isolation.
        ● It supports?ethernet loop detection, can automatically judge whether there is a ethernet device network loop blocking .When loop disappears, it can automatically recover.
        ● It supports multicast VLAN.
        ● It supports remote loopback and remote diagnosis of network status.
        ● It possesses rich OAM functional design, including configuration, alarm, performance monitoring, fault isolation and safety management, etc. It can provide the OLT remote management, and support local management. Technical Specifications
