At present, optical fiber products have become the world's leading communication transmission medium, which is not only used in the communication industry, but also widely used in sensors, medical detection, aerospace industries and other fields. For the testing of optical fiber materials, it mainly includes procedures, tools and standards for testing optical fibers and components, optical fiber links and optical fiber deployment. These tests include optical component and mechanical tests, as well as tests to verify the integrity and comprehensiveness of the complete fiber optic network.
