Distributed fiber optic sensors (DFOS) are the market facing most of the risks, which are technological risks mainly because of the complexity of fiber optic systems. Sensor calibration, signal attenuation, and environmental factors such as temperature fluctuations can affect the performance of the product. Companies are required to do research, and, in this way, they can come up with innovations to the product that will make it sensor accurate and more reliable. However, their operational costs will increase, and they will take more time in product development processes.
Enhancing Lensmaker's Equation capabilities of such fiber optic cables can make the product more expensive during manufacture, making it hard for new companies to enter this field easily. Apart from that, the high initial investment required for special installation technicians makes it a challenging solution compared to traditional ones. Another significant risk is the competition from other sensor technologies.
Classical electronic sensors and wireless monitoring systems are also being upgraded, which makes them cheaper than before. Suppose the DFOS programmers are not capable of overcoming the challenges by providing a higher performance, integration, and lower price. In that case, that is to say, if they do not create value for their customers, then they will likely face difficulties in fostering a competitive edge.
