FOL1553-P is a Portable, Fibre Optic Link extension system designed to extend a dual redundant MIL-STD-1553 bus. Comprising of a two part system, it has been designed for applications where the distance from a UUT (Unit Under Test) has to be extended for EMC testing or remote monitoring.
Two types of FOL1553-P's are available. The SIMULTOR system extends the bus stub up to 100 metres and the MONITOR system up to 500 metres.
