Pure Silica Core Fiber
Z Fiber® / Z-PLUS Fiber® – World's lowest attenuation record 0.148dB/km
Pure Silica Core Fiber was developed in 1980's and mainly used for submarine optical cable applications or other R&D activities in which extremely low attenuation is required. The typical attenuation at 1550nm is 0.170dB/km for Z Fiber® and 0.168dB/km for Z-PLUS Fiber®. The fiber also has excellent performance against Hydrogen & Radiation because no Germanium is doped in manufacturing process. Special heat resistant coatings or a fiber in a stainless steel tube is available for harsh operating environments.
