In the oil and gas industry, there are two main uses of optical fiber, one is sensing, the second is communication. Fiber optic sensors have significant advantages over electrical sensors because they are small, can work at high temperatures, reduce the risk of failure when exposed to water (or other conductive liquids), and do not require power from the sensor head.

In addition to optical fiber sensors, the oil and gas industry also uses optical fiber communication technology, allowing Subsea equipment performs higher bandwidth communications and reduces the size and weight of communications cables by replacing copper cables with optical fibers.

The environment where oil and gas optical fiber sensors need to operate requires specially designed optical fibers to ensure their use Life and performance exceed historical technology. In many sensing applications, standard telecom optical fibers will not be suitable, so the optical fiber core has designed a series of special optical fibers specifically designed for the oil and gas industry.
