Ethernet cmts docsis 3.0 /docsis2.01.Built-in CMTS module,CATV optical receiving module and ONU module;
2.high integration.
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.
The CMTS module inside JH-DN3416 adopts JH- DOCSIS 3.0 CMTS core. It has as much as 16 QAM downstream channels with 1.1Gbps data rate and 4 QPSK/QAM upstream channels with a maximum of 160Mbps data rate. The data interfaces of CMTS module include 1000Mbps port (RJ45) and 1000Mbps SFP. D-node also has an optional ONU module for choice so that it can connect to EPON as well as the Ethernet. The CATV optical receiver and the amplifier module with 1000MHz bandwidth , added with the use of CNC equilibrium regulation technology and attenuation make it easy to realize remote control
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
