FutureGuide®-SR15E-200 ITU-T G.657.A1 (+ 200µm Coating Diameter)

Product code : LZSY49

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.


  • Reduced coating diameter down to 200μm with tolerable microbend performance
  • Improved macrobend performance complying with ITU-T G.657.A1
  • Zero(low)-water peak attenuation complying with ITU-T G.652.D
