JH-DN***6 is a D-node device which integratesCMTS 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-DN***6 adopts JH- DOCSIS 3.0 CMTS core. It has as much as *6 QAM downstream channels with 1.1Gbps data rate and 4 QPSK/QAM upstream channels with a maximum of **0Mbps data rate. The data interfaces of CMTS module include ***0Mbps port (RJ*5) and ***0Mbps 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 ***0MHz bandwidth , added with the use of CNC equilibrium regulation technology and attenuation make it easy to realize remote control
