As the Internet of things is one of the extremely important component, the optical fiber sensor because of its advantages and application have been much attention. From the global market, in 2013 the global market size of $1890000000 for optical fiber sensor. Is expected from 2014 to 2018, the global optical fiber sensor market will grow at an annual growth rate of 18%, to 2018 the market size to $4330000000. From the research of optical fiber sensing technology point of view, the United States to study this technology started first, and the most advanced in the world. Data show that in 2007, the size of the U.S. fiber optic sensor market is $235000000, then to 30% compound annual growth rate of growth, in 2014 is expected to reach US $1600000000.
Compared with America, the optical fiber sensing industry of China is in the initial stage. According to statistics, as of the end of 2013, China 20000000 yuan of above scale sensor manufacturing enterprises have more than 260. But the overall quality of the industry is uneven, small and medium enterprises accounted for nearly 70%, to the production of low-end products; few leading enterprises and foreign-funded enterprises occupy the high-end product market.
