Fiber Optic Modems

The FOM-IP/1 integrates the MD1272/G and IP/1 10/100 Mbps fiber optic modems that provide a ruggedized optical link between mobile shelter equipment and remote sites for tactical communications. This unit provides electrical to optical conversion of IP (Internet Protocol) data and electro-optical conversion for full duplex transmission of digital communications signals between tactical shelters using multimode tactical fiber optic cable assemblies and is designed for use in harsh environments.

The interface at each end of the multimode optical cable converts between electronic and optical transmission modes for repeaterless communication at distances of up to 2 kilometers. The FOM IP/1 automatically configures itself for 10 or 100 Mbps operation and is available with various tactical fiber optic connectors, including *TFOCA-II® and Expanded Beam.
