• The FOM-6AV, Asynchronous Fiber Optic Modem, is used for local data distribution connecting full or half duplex async DTEs. A pair of modems ensures integrity of data transmission over fiber optic cable at data rates up to 64 kbps.

• FOM-6AV features switch-selectable DTE/DCE. This allows operation as DTE, for connection to another DCE such as a multiplexer port, eliminating the need for a cross-cable. The carrier can be strapped for either continuous operation or switched operation, controlled by the RTS signal, for transfer of a control signal end-to-end. A LED indicator lights whenever data transmission takes place.

• Innovative circuitry allows FOM-6AV to operate without connection to the mains supply, by using ultra-low power from the data and control signals. FOM-6AV operates even if only Transmit Data is connected, i.e. no control signals or any other source of power are required.

• FOM-6AV is furnished in a miniature plastic enclosure.

• FOM-6AV incorporates all the advantages of a fiber optic system, providing:
  • Lower attenuation than with copper wire;
  • EMI/RFI immunity, saving the cost of expensive and heavy shielding, and complex error checking routines;
  • Almost absolute security and reduction in the cost of data encryption;
  • Eavesdropping is virtually impossible as negligible power is radiated from the fiber;
  • Safety and electrical isolation: no spark hazard and no ground-loop noise problems.
