FutureGuide®-SS ITU-T G.655.C and D (Small-dispersion-Slope NZ-DSF)

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.

Fujikura PANDA fibers have a superior optical property in polarization-maintaining because of the symmetrical accuracy in cross section and the uniform constitution of stress applying parts. Based on Fujikura's fiber technology, PANDA fibers have a universal quality with not only low polarization-crosstalk and low attenuation but also the broad suitability for fusion-splice or optical connector.

Fujikura's large core optical fibers are made of silica glass, thus have excellent transmission characteristics over the selected wavelength range, one is from UV to VIS, the other is from VIS to NIR. Moreover with its large core size it also can transmit high energy density of laser beam, which is demanded for applications of laser processing, laser therapy, optical sensors and spectral analyzers of weak light.

Fujikura's single-mode optical fiber with high temperature resistant acrylate coating protects the optical fiber up to 200°C (short term). The fiber is applied to harsh environments like Oil & Gas industry. Figure1 shows the results of attenuation variation in 200°C. We obtained not more than 0.01 dB/km variations at both 1310 nm and 1550 nm. Table shows the specification of the fiber.
