PL20-4A RFoG MDU with xPON

PL20-4A rfog optical node (RFoG MDU) ( can set as OBI Free RFoG Node) is the ideal platform for use in FTTH and FTTB networks. It can deliver upstream and downstream DOCSIS, voice, video and high speed data service over FTTX applications. PL20-4A mini node ( can set as OBI Free RFoG Node) is designed to EPON/GPON network to expend CATV service.
