Due to the flourishing development of the optical communication in recent years, people enjoy more convenient and faster data transferring speed. At optical communication industry, optic fibers are a part of the passive hardware components. Because the optical fiber has more benefits compared with traditional cable in data communication, such as low loss and more suitable for long-distance transmission. Just as the name implies, optic fibers play the core component in the fiber optics sensors. Figure 1 shows the structure of the typical optical fiber. The price of optic fiber is cheap and the whole communication industry has reached economic scale. For this reason, the related accessories are very rich and easy to get. It helps to create a new niche optical sensor market upon the above-mentioned benefits. In optical communication industry, silica based fibers are adopted for transmission. |
