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

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.
