In the context of global sustainable development, the use of geothermal energy is an important issue for future energy supply.  Water and steam can bring geothermal energy to the earth's surface, and depending on its properties, it can be used for heating and cooling or to generate clean electricity.  

Unique monitoring and characterization challenges of geothermal reservoirs.  Temperature and pressure change is one of the important problems to be solved in the process of using geothermal water or geothermal steam.  Changes in temperature and pressure affect balance and can cause scaling on well walls, streamlines, valves, turbines, etc.  At the same time, the harsh and high temperature geothermal downhole environment requires advanced and robust measurement technology.  This is why fiber-optic sensors can be used in geothermal Wells.  Optical fiber sensors have the inherent advantages of remote operation, small size and good robustness.  

Polarization-maintaining fiber, which is the core of fiber sensor, has the characteristics of high sensitivity and high precision. Extinction ratio is very important as an important index to measure the performance of bias keeping. The Shinho S-12PM is a dedicated Fusion splicer for splicing polarization-maintaining fibers. According to testing and feedback from many customers, the extinction ratio loss is less than 1dB. Reaching the advanced world level.

PM Fiber is more and more important in our life. Shinho will discover more applications and solutions together with our customers.
