EPON ONU with 4 ports 10/100 Fast Ethernet & 2 FXS phone ports, 1 uplink PON port.


4 ports  Fast  Ethernet  & 2 FXS voice type EPON ONU is one of the most popular ONU's used in FTTH deployments till now. It has 4 Ethernet ports and 2 FXS ports  and can be used for example for 1 port connecting whole customers LAN, for example, connecting home wifi router, or directly to PC, and another ports can be used to connect IPTV set top box, network storage, or more PC's. Most important here - you can start providing a phone access to your FTTx customers just merely installing this ONU at CPE premises, and connecting regular POTS phone to any of 2 FXS ports. ONU serves as VoIP client gateway. So, 4 port and 2 voice EPON ONU can be used in:

  • Small and mid sized and big ISP's;

  • Regional level carriers who want to organize fast development of FTTH access

  • Hotels and resorts who want to establish triple play over a fiber

  • Local Area Networks;

  • CCTV IP camera surveillance

Modern networks rarely rely on pure topologies like bus, ring, or star. Most common solutions use hybrid topologies, which are combinations of features from those three.   Star-Wired Ring As it is clear from the name, star-wired ring topology has features of star and ring topologies. You can see example of this topology ...
