Abstract
A measuring device including a measuring equipment that is configured to be optically interrogated by a measuring instrument with first optical signals in a first wavelength range, and a connecting optical fibre for optically connecting a measuring equipment to a measuring instrument. The connecting optical fibre includes at least a first optical core that is multimode in the first wavelength range and a second optical core that is single-mode in a second wavelength range. The connecting optical fibre includes at least one first segment of functionalised optical fibre that is such as to exhibit, at the second wavelength, and optical property that varies with an environmental parameter of the connecting optical fibre. The invention also relates to a measuring assembly and to an apparatus that includes such a measuring assembly.
