FutureGuide®-SM ITU-T G.652.B (Standard Single-Mode Fiber)

FutureGuide®-SM ITU-T G.652.B (Standard Single-Mode Fiber)

In 1976, Fujikura achieved the world's lowest attenuation record, 0.47dB/km. Ever since then Fujikura has always been the industry's leading optical fiber manufacturer. ITU-T G.652.B is the most commonly used optical fiber for long-distance terrestrial application.
