Paper Abstract

Double-ended configuration is commonly deployed in Raman-based distributed temperature sensing (DTS) systems to achieve a high accuracy in temperature measurement. To show the feasibility of multicore optical fiber (MCF) in this application, we will demonstrate distributed temperature measurements using a sensor consisting of a dual-core MCF and an integrated, distal end turn-around in a doubled-ended configuration. The dual-core fiber and turn-around, both coated with polyimide, are suitable for high temperature use. Additionally, the device is ideal for long length, distributed temperature detection in confined spaces, with a finished outer diameter of less than 300 μm. The results show that wavelength dependent loss (WDL) is easily removed in the setup and an accurate temperature measurement can be achieved reliably over a wide temperature range.
