Nyob rau hauv high-speed fiber kev sib txuas lus, kev nthuav dav ntawm cov teeb liab modulated tshwm sim vim cov nyhuv ntawm chromatic dispersion. Yog tias tsis muaj qhov nyiaj them poob haujlwm DCM, txhua lub teeb liab yuav raug nthuav dav,
thiab txawm sib tshooj nrog cov teeb liab uas nyob ib sab. Txawm hais tias cov nyhuv dispersion tsis muaj zog heev, lub teeb liab yuav raug deformed heev vim yog crosstalk ntawm cov teeb liab. Yog li ntawd, kev them nyiaj dispersion yuav tsum tau ua ua ntej lub teeb pom kev pom.
