Abstract

Distributed Fiber temperature Sensor is a high and new-technology industries that it can be used to measure real-time temperature field distribution of space, WDM (Wavelength Division Multiplexer) is widely used in distributed fiber temperature sensor besides in optical fiber communication system. The characters of WDM especially the isolation and insert loss play an important role in the characters of the sensor. In this paper, the structure of the distributed fiber temperature sensor with WDM applied on was given first. Then the isolation and the insertion loss of WDM are discussed. Analysis and calculation results will be expressed that in this system the characters of WDM determine the accuracy of measurement of temperature.
