mark of the communication domain. As the development of the technology of the IOT
and the fiber-optical sensor, the combination of the both is a big question to be
discussed, and the fiber-optical IOT also has a good development prospect. This
article first introduces IOT ’s current status, the key technology, the theoretical frame
and the applications. Then, it discusses the classification of the optical fiber sensor as
well as the development and its application’s situation. Lastly , it puts the optical fiber
sensing technology into the IOT, and introduces a specific application which is used
in the mine safety based on the fiber-optical IOT.
