The construction of the optical fiber laboratory was completed in November 2016, guided by the development direction of the optical fiber industry, focusing on technical research and optical fiber performance testing, covering optical fiber environmental performance and mechanical performance testing. The laboratory is equipped with test equipment for water immersion test, high temperature and high humidity (damp heat) aging test, high temperature (dry heat) aging test, temperature cycle test, hydrogen damage aging test, peel force test, tensile force test, macro bending test, and Nd test. , It can test G.652D, G.657, 200μm small diameter fiber and other fiber types. Among them, G.652D and G.657 fiber products have passed Tyre certification.
