Abstract :
In high-speed transmission systems, group velocity dispersion (GVD) equalization is indispensable if previously installed fiber cables are used because they have various zero-dispersion wavelengths. From the viewpoint of economy, neither manual equalization nor worst-case system design is practical in future high-speed systems. This paper introduces automatic equalization for installation of future high-speed systems and a simplified system has been demonstrated; the GVD of a 10-Gbit/s 1000-km transmission line was successfully equalized in an automatic manner
