eoc (ethernet over coax) is mainly used in catv bidirectional network transformation. eoc system consists of ha3200 series eoc master, ha300 series eoc salve and coaxial distribution network.
catv signal from the catv optical transmitter and ip signal from ip transmitting equipment in the control center, transmit to ha3200w eoc master at the optic node, ha3200w integrates the two signals and then output from the hybrid rf port to coaxial network. if there are one way rf amplifiers connected in the distribution network, ip signal can’t return from user end eoc slave to eoc master, bridge needed to implement bidirectonal communication.
ha302 eoc slave at user end devides the ip signal and catv signal, offers two 10/100m rj45 output ports and one rf cable port. ethernet ports for pc and voip, and cable port for catv.
