EPON ONU with 4 ports 10/100 Fast Ethernet, 1 uplink PON port. Can be used in semi-FTTB or FTTH dense urban household connections when up to 2 users can be connected using same ONU without a switch.


4 ports  Fast  Ethernet  CATV ONU is one of the most popular ONU's used in FTTH deployments till now. It has 4 Ethernet ports and 1 CATV port 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. 4 port and 1 CATV 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 ...
