Measuring device with an optical connecting fiber and a measuring instrument for the instrumentation of an aeronautical system, as well as an aeronautical system containing such a measuring instrument.

Abstract

The invention relates to a measuring device (10) comprising an item of measuring equipment (30) that is configured to be optically interrogated by a measuring instrument (20) by means of first optical signals in a first wavelength range, and a connecting optical fibre (100) for optically connecting an item of measuring equipment (30) to a measuring instrument (20). The connecting optical fibre (100) comprises at least a first optical core (111) that is multimode in the first wavelength range and a second optical core (112) that is single-mode in a second wavelength range. The connecting optical fibre (100) comprises at least one first segment of functionalised optical fibre (120) that is such as to exhibit, at the second wavelength, an optical property that varies with an environmental parameter of the connecting optical fibre (100). The invention also relates to a measuring assembly and to an apparatus that comprises such a measuring assembly.
