FutureGuide®-LA ITU-T G.655.C and D (Large-effective-Area NZ-DSF)

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.

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.

Optical fiber networks in urban areas demand more effective utilization of available space by installing high density and more fiber-count cables underground. Especially, such demand is increasing in access network. Employing our innovative fiber coating technology in FutureGuide®-BIS-B, we launch a new ITU-T G.657.A2 fiber with 200μm coating diameter named FutureGuide®-BIS-B-200. The fiber has drastically reduced coating diameter, while keeping microbend characteristics equivalent to conventional fibers. The 200μm coating diameter with tolerable microbend performance allows around 40% reduction of cable cross-section area. In addition, superior macrobending performance helps to install optical cables into narrower spaces with easy handling. This new fiber strongly contributes to not only more effective utilization of available space but also saves costs of manufacture, transportation and installation of cables.

FutureGuide®-SS is designed with small-dispersion slope, optimizing for the use of wider range of wavelength with relatively smaller chromatic dispersion at 1625nm region. FutureGuide®-SS is suitable for DWDM application in C- and L-bands.
