This paper proposes an optical transmission system with automatic dispersion equalization for exploitation of the fiber capacity without additional installation cost. The system has two operational modes: “measurement-mode” wherein dispersion is measured by phase-to amplitude-modulation conversion, and “data-transmission-mode” for providing telecommunication services. Dispersion equalization is realized by the accompanying use of dispersion compensating devices and wavelength tuning to the zero-dispersion of the optical fibers. Supervisory-channel communication enables remote operation. We demonstrate a simplified system; the dispersion of a 10 Gb/s-1000 km transmission line is successfully equalized in a fully automatic manner. Equalization with the preciseness of 10.1 mn from the zero-dispersion wavelength provides penalty free transmission or better performance with optical input power under the Brillouin threshold
