The defence industry was one of the first industries to embrace fibre optic technology. This was originally for communications however, the uses are broadening. The fibre optic network is utilised from communications, performance, sensing but it is its overall easy and reliability. The total electrical isolation of fibre makes it a safer, spark free media for use in hazardous environments where volatile gasses may be present. Fibre Optic networks can transmit a mind boggling quantity of data and up to 150 times the data carrying capacity of bulkier copper cable and run longer distances.
