What is distributed temperature sensing fiber optic cable?

Distributed temperature sensing fiber optic cable provides a mean to obtain very accurate temperature measurements. When use in conjunction with distributed temperature measurement equipment, it will function as a linear sensor which enables temperature to be taken along it. Temperature can be measured over long distance with high precision of ±1°C. It can be used in a variety of areas where distributed temperature measurements are required especially in areas with limited access such as the tunnels, mines and bridges.
