The H645G is mini Optical Network Terminal (ONT) compliant with ITU-T G.984 standard. DASAN Networks has developed H645G for all clients on the basis of Gigabit Passive Optical Network (GPON) technology. GPON technology supports upstream 1.25Gbps and downstream 2.5Gbps data transmission rate. With DASAN?s leading-edge GPON technology, users can enjoy bandwidth-consuming multimedia services such as real-time video, audio and gaming much easier and faster than ever before. The H645G is comprised of one GPON uplink and Gigabit Ethernet downlink supporting 10/100/1000Base-T (RJ45). It helps service providers to extend their core optical network all the way to their subscribers, eliminating bandwidth bottlenecks in the last mile. With the GbE service interface, it delivers data at the speed of 1000Mbps to the connected subscriber equipment. The H645G utilizes technology for intelligent IP-based access allowing reliability of network deployment models and management system.
