What is fiber optic leak detection?

• Fiber optic leak detection uses distributed optical fiber sensors installed along pipelines to continuously monitor for changes in temperature, вібрація, or acoustic signals that could indicate a leak.
• Technologies such as DTS, DVS, and DAS transform standard fiber optic cables into sensitive, real-time detectors that cover the entire pipeline length, providing comprehensive protection against leaks and third-party interference.
• This method is crucial for oil, газ, and water pipelines, particularly in large and environmentally sensitive regions like the Middle East.

How does DOFS (DTS, DVS, THE) work for leak detection?
