FutureGuide®-LWP ITU-T G.652.D (Low(Zero)-Water-Peak 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.

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.

As the number of channels increases with DWDM, the higher intensity of light in a fiber induces various non-linear effect of light, causing signal distortion in a long span. Fujikura have developed FutureGuide®-LA, which is designed for inhibiting non-linear effect with non-zero dispersion characteristic at 1530-1565nm region and with large effective area, offering for long distance DWDM transmission in C and L bands.
