This paper presents a simulation and an experimental quasi-distributed Fabry-Perot optical fibre sensor for temperature measurements implemented on a serial array using a combined frequency division multiplexing and wavelength division multiplexing arrangement. Quasi-distributed fibre sensors have been of great interest in the industry for the monitoring of power transformers, jet engines, and furnaces. This paper is aimed at providing theoretical results for a quasi-distributed sensor system made of 25 local sensors imprinted on a serial array of the single mode fibre whereby the local sensors are of weak reflectivity. In addition, a sensor system of nine quasi-distributed local sensors is experimentally tested and a sensitivity of 10 pm/°C and a resolution of 0.125°C are obtained. Its higher resolution, higher spatial distribution, and ability to measure temperature at different points simultaneously make it a very attractive temperature sensor.
