JH-DN3416 is a D-node which has built-in CMTS module and CATV optical receiving module and ONU module (optional), those two optical input port connects upwards to CATV fiber and IP trunk fiber and the four high level output RF ports can connect to cable distribution network directly. D-node could finish CATV photovoltaic conversion, IP data photovoltaic conversion and mixture transmission of data and TV signals, actually, it is an “Integrated Service workstation”.
The built-in CMTS module in JH-DN3416 adapts the Jinghong D3 series CMTS core which accord with DOCSIS 3.0 standard, there are 16 QAM channels which has 1.1Gbps data rate; for upstream, there are 4 QPSK/QAM channels which could reach up to 160Mbps.For data port, there are 1000Mbps power port (RJ45) and 1000Mbps optical port (SFP). There is also built-in ONU module (optional) for choice, it can work not only with Ethernet but also connect to EPON. There are also built-in CATV optical receiver and 1000 MHz bandwidth RF amplification module. It adapts CNC equilibrium and attenuation adjustment, can be operated via remote control.
JH-DN3416 can completely replace the current optical node equipment which could simplify the HFC network structure. Its excellent transmission capability can meet the NGB requirements completely which enable itself to be the core equipment of triple play projects.
