JH-DN3416 is a D-node device which integrates CMTS module ,CATV optical receiver and ONU module (optional). Its two optical ports are respectively connected CATV fiber and IP fiber trunk while its four RF port with high output level directly connect coaxial distributive network. Since D-node achieves CATV O/E conversion, IP data O/E conversion and transmission of mixed data and television signal, it is in fact a full service optical node.
JH-DN3416 simplifies HFC network and is fully available to replace the existing optical node device. Its superior transmission capacity meets all the requirements of NGB and, therefore, could be chosen as the most appropriate equipment of triple - play bundling.
