This solution implements bidirectional network transformation based at HFC netowrk. As the EPON network structure is similar to HFC network structure, no need to greatly change the exixting HFC network. Just set the headend equpment OLT at the control center, connect to a preserved fiber, then connect to the splitter. IP signals split to the terminal equipment ONU at optic node. Then IP signal is access to the optic nodes.
Access user home network adopts EOC technology to implement "last mile" access. EOC master at the optic node integrates the CATV signal and IP signal, then transmit to EOC slave through coxial distribution network. Then EOC slave devides the CATV signal and IP signal. EOC salve offers one cable output port for CATV and two 100M output ports for internet and VOIP, so to implement triply play services access.
