Abstract
Because of increase of communication bandwidth demand, upgrading the speed of optical fiber networks is a future issue. However, in the case of high speed transmission at wavelength of 1.5 μm band on the existing single mode fiber, transmission distance is limited due to chromatic dispersion. Thus, in addition to chromatic dispersion compensation devices, automatic optimization methods of the compensation value are important especially in the case of photonic networks, on which transmission distances often change dynamically. But problems remain such that signal quality measuring instruments are expensive under existing automatic chromatic dispersion compensation methods.In this report, focusing on spectrum profile change by long transmission of optical signals, a simple automatic control method of chromatic dispersion compensation is proposed. And some results of basic experiments are described. By doing feedback control for optimizing the chromatic dispersion compensation value, an error-free state of a 10 Gbps optical signal is demonstrated even if the dispersion value of the transmission line is rapidly changed.
