Optical Media Converter - BRUMIL 451 OMC

Optical Media Converter - BRUMIL 451 OMC

The Optical Media Converter is a media converter for easy conversion from fiber based to copper based Ethernet and opposite. A hardened device designed for indoor and outdoor applications in rough environments. Two media converters can expand an Ethernet link over long distances.


•Temporary long distance Ethernet-data-links e.g. between military checkpoints, command posts and headquarters in harsh environmental conditions

•Expanding an Ethernet connection over long distance with tactical fiber optical cable

•For tactical fiber-optic cable e.g. with military lens connectors.

•For indoor and outdoor use

•Easy integration & operation


•The OMC is equipped to cover FO/electrical-media- converter function for TCP/IP protocols. The function is used to extend the data transmission of an Ethernet channel by fiber optical lines. The OMC is especially designed for the use in harsh environmental conditions. At the front panel there are MIL-grade connectors available to interface with tactical optical-fiber-cable, copper-data-cable and power connections (AC or DC or both).

•The standard configuration includes one HMA compatible optical interface and one electrical MIL-grade-RJ-45- interface (10/100/1000BaseT) for bit rates up to 1 Gb/s, with automatic sensing. Crossed or uncrossed wire cables are detected automatically by the OMC. The FO- interface is fixed to 1Gb/s bit rate

•The maximal cable length at the optical single mode interfaces is 10km (depending on the number of connectors in the line) and 100m at the Cu-data- interfaces
