RAD M-EFC Miniature Ethernet-to-Fiber Optic Converters 


  • M-EFC is a Miniature Ethernet Fiber Optic Converter/Transceiver. It converts the IEEE 802.3 electrical signals into optical signals for transmission over fiber optic cable, and is fully compatible with IEEE 802.3 10BaseFL and FOIRL standards.
  • Two switch-selectable operating modes are available. Half duplex mode is used when connecting hub ports and other half duplex devices. Full duplex mode is used when connecting full duplex ports of switches, routers or workstations. In this mode, M-EFC takes advantage of the unlimited range available on full duplex links (limited only by media attenuation).
  • M-EFC supports 62.5/125 micron multimode fibers and 9/125 micron single mode fibers.
  • The unit plugs directly into the DB-15 AUI interface or connects via an AUI cable and is powered via the AUI interface (12V).
  • The fiber optic cable used by M-EFC increases range, improves network performance and achieves greater reliability. It also reduces susceptibility to electrical noise and radio interference, and increases communication security by providing immunity to tapping and eavesdropping along exposed cable segments.


  • Provides fiber optic connection for any Ethernet device
  • Supports workstations, routers, hubs and switches
  • Supports 10BaseFL and FOIRL IEEE 802.3 standards
  • Supports half/full duplex Ethernet
