    ITU-T G.652.D (Low(Zero)-Water-Peak Fiber)


ITU-T G.652.D (Low(Zero)-Water-Peak Fiber)

ITU-T G.652.D is the standard optical fiber and occupies more than 80% of world optical fiber demand.
Fujikura's FutureGuide®-LWP has proved its reliability and performance for more than a decade. Integrated with the highest quality of the coating material developed by Fujikura, the optical and mechanical characteristics of FutureGuide®-LWP remain totally stable under the harshest environment such as -60 to 85 degrees temperature. Our optimized VAD (Vapor Axial Deposition) method of fiber preform manufacturing achieves the industry's lowest attenuation level of water peak at 1383nm, enabling the future expansion of transmission capacity at E-Band.
