New optical fibers for high bit rate and high capacity transmission

Youichi Akasaka

New optical fibers for high bit rate and high capacity transmission, which were developed for future all optical transmission line and submarine cable, are introduced. These fibers are designed not to have dispersion dependence against wavelength in total link transmission.
