近几年来，物联网发展飞快。光纤通信与光纤传感技术将在物联网领域发挥重要作用。光纤具有宽带特性，可将各种传感器复用到一根光纤，进行检测和传输。由于光纤本身具有电绝缘性好、不受电磁干扰、无火花、能在易燃易爆的环境中，还具有成本低、结构简单、可靠性高等优点，光纤材料用做传感器具有独特的优势。物联网与光纤传感有相辅相成、相互促进的作用。各种光纤传感器有望在物联网中得到广泛应用。

ABSTRACT

The Internet of things develop quickly in recent years. Optical fiber communication and optical fiber sensing technology will play an important role in the field of Internet of things. Optical fiber have broadband characteristics, various sensors can be reused to a single fiber to text and transport. Because of the fiber’s good electrical insulation, not subject to electromagnetic interference, no spark, can in inflammable and explosive environment , also has the

advantages of low cost, simple structure, high reliability , optical fiber materials used for sensor has a unique advantage. The Internet of things with the optical fiber sensing supplement each other and promote each other. All kinds of optical fiber sensor is expected to be widely used in the Internet of things.
