Single Channel FOMs


The single channel FOM is currently available in four standards based communications interfaces: The standard U.S. Army FOM MD-1272/G, Eurocom D/1 Interface B, E3 and DS3. These modems transmit up to 16 km without a repeater. The single channel FOM’s are designed to mount on the Signal Entry Panel (SEP) of the tactical communication shelters or they can be installed in a rack mount panel. FOM’s are available with various tactical fiber optic connectors, including TFOCA, *TFOCA-II® and Expanded Beam.
