FutureGuide®-SR15E ITU-T G.657.A1 (Improved Bend Insensitive Fiber + ITU-T G.652.D compliance)

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.

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®-SR15E we launch a new ITU-T G.657.A1 fiber with 200μm coating diameter named FutureGuide®-SR15E-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. 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.

Just like FutureGuide®-SR15E, FutureGuide®-BIS-B is also designed for compact storage in tight space of a building, but allowing even smaller fiber bending radius than FutureGuide®-SR15E fiber with excellent bending loss performance. FutureGuide®-BIS-B is suitable for aerial drop cable, indoor cable, patch cord or any FTTx application cable.

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.
