G.fast ONU HN5124D G.fast ONU
GPON Uplink


G.fast is a new technology based on VDSL2 which uses telephone lines to support Internet service up to 1Gbps.


Some old buildings are not able to be serviced with Giga Internet access because of deployed cable infrastructure or lack of lines. In those cases, G.fast can service Giga Internet access even without extra Optic cables or newly added UTP cables.


HN5124D is a Layer 2 switch for workgroups that transmits traffic from personal PCs or web servers on the network to the backbone equipment. HN5124D provides a 10 / 100 / 1000BASE-T service port supporting wire speed in the form of optional modules. According to the user s environment, the uplink port can be installed by selecting 1000BASE-X (SFP) or 100BASE-Fx or 1G-PON port to create various network environments.



HN5124D is a member of the cost-effective and highly scalable Broadband Access
