Fibre Ethernet Converter Single Mode Multimode Bi-di WDM

Fibre Ethernet Converter (ENTU763) FE and GE are so-called Ethernet Access Devices (EAD), Ethernet Media Data Converter (MDC) or Ethernet Fiber-optic Modem (FOM). It is a manageable type of media converter that is interoperable with Ethernet Access Chassis (iEAC-16). The customer premise allows the operator to reach customers over fibre, while still providing a standard Ethernet copper connection.
