The FOCI is a powerful Ethernet or Gigabit Ethernet media converter which is used to carry Ethernet link over fibre and to control distant access. This device is used as a CPE for the Media Converter Center, AMS-MEDIA16-SNMP populated with FOCIR slide-in cards. This solution is particularly appreciated in large infrastructures to control all links including the distant UTP interfaces connected to the customer equipment. All functions, Ethernet statistics, rate, protection and test of loop are SNMP controlled from the Media Converter Center. The management between card and distant modules is operating in-band of the fibre.
