FOM-5A ( FOM-5A/F/ST, FOM-5A/M/ST)  asynchronous fiber optic modems

FOM-5A  ( FOM-5A/F/ST, FOM-5A/M/ST )

FOM-5A  modems ( FOM-5A/F/ST, FOM-5A/M/ST )  are asynchronous fiber optic modems that are used for local data distribution to connect full or half-duplex async computers and terminals. A pair of modems ensures integrity of data transmission over fiber optic cable at distances of up to 3 km (1.8 mi).

FOM-5A is only 78 mm (3.1 in) by 18 mm (0.7 in) 

FOM-5A ( FOM-5A/F/ST, FOM-5A/M/ST) features a switch-selectable DTE/DCE option. This allows operation as DTE for connection to a DCE, such as a multiplexer port, eliminating the need for a cross-cable. To transfer a control signal end-to-end, the carrier can be strapped for either continuous or switched operation and controlled by the RTS signal. A LED indicator lights whenever data transmission takes place.

The delay between Request-to-Send and Clear-to-Send can be set to 2 or 15 msec. FOM-5A  operates without connection to the mains supply, by using ultra-low power from the data and control signals.

FOM-5A ( FOM-5A/F/ST, FOM-5A/M/ST )  provides all the advantages of a fiber optic system:
- Lower attenuation than copper wire
- Immunity to EMI/RFI and noise eliminates the cost of expensive and heavy shielding and complex error checking routines
- High data security reduces costs of data encryption. Negligible power radiation from the fiber makes eavesdropping virtually impossible
- Safety and electrical isolation: no spark hazard and no ground-loop noise problems.
Note: Attenuation is not related to frequency.
