The FOVC is a secure fibre optic communications system specifically designed for use in taxing test environments including high EMC and Lightning scenarios.
Aircraft have to be able to operate in very demanding environments, including very close proximity to high power RADAR and other transmitters. In order to ensure that the sophisticated electronics on board will work properly part of the design process demands that such aircraft and vehicles are “illuminated” by such RADAR systems at distances of just a view tens of feet. The essential communications required during such tests means that the use of copper conductors between the control centre and the aircraft or vehicle under test is simply not possible.
This problem has been solved with the FOVC a fibre optic communication system. The system is contained in two fully screened units, each equipment allows the use of up to four standard military headsets giving perfect clarity of communication in this very demanding area of testing thereby allowing DMST to play an important role in military vehicle development.
This compact system provides a secure voice communications net with fibre optic modem transmission; the system is fully multiplexed for up to eight users. Two interchangeable units are used as a secure medium distance communications system connected together via fibre optic cable. Built into the system is an aircraft interface that allows communications with most modern aircraft voice communication systems.
The system incorporates tone transmission via a dedicated internal modem. The design offers mains and battery operation. A 100-metre reel of multimode fibre optic cable is provided as standard. External connections can be made via the side panel when the unit is fully closed down
The FOVC has been used on various aircraft including the Merlin (Mk3), Apache, Sea King, Tornado, Phantom and Harrier.
