Abstract

A field experiment on transmission of 80-Gbit/s-based wavelength division multiplexing (WDM) signals is successfully carried out. In order to keep good transmission quality, technique of an in-service dispersion monitoring and an adaptive control of the chromatic dispersion are proposed. Difference of the propagation delay between channels caused by the chromatic dispersion of the transmission line is detected using signals superimposed on the envelope of the WDM pulses. Dispersion alteration of the transmission line is estimated from the measured delay in real-time. Accuracy of the method is clarified through a transmission experiment using wound fibers in an oven changing their temperature. The field experiment on 80Gbit/s × 8WDM transmission using an OPGW with 60km × 2spans is carried out and fine BER performances are obtained in all channels. Transmission properties are found to be stable owing to the dispersion control techniques throughout the field trial.
