Automatic dispersion compensation device and compensation method |
摘要 |
The automatic dispersion compensation device of the present invention comprises a unit measuring the transmission quality of incoming optical signals for one or more channels input from a transmission line and a unit separating and detecting the transmission quality degradation due to chromatic dispersion, in the measurement result of the unit from degradation due to other factors and controlling a variable chromatic dispersion compensator (VDC) in such a way as to compensate for that degradation.
