Optic Fiber

ZTT is a world-class optical fiber manufacturer and supplier, which has independent core intellectual property rights of optical fiber. So far, ZTT fiber is reference in 138 countries globally. ZTT optical fiber can be applicable for transmission system rate up to100Gb/s, and also has supporting technologies for 400Gb/s system.


Design & Construction


ZTT has her own research and development center, from fiber preform to optical fiber. ZTT have the unique fiber drawing technology, produce high quality products. ZTT optical fiber, which is made of high purity SiO2, Ge and coating acrylic resin, provides large capacity and fast speed for data transmission.

Reference Standards

ZTT fiber meet the international standards of ITU and IEC series (such as ITU-T G.652, G.655, G.657, G.651, IEC 60793 etc.) and can be supplied according to customers’ requirements of standards.
