Lapho i-voltage yengezwa kukristalu ye-electro-optic, inkomba ye-refractive kanye nezinye izici zokubona zokushintsha kwekristalu, shintsha isimo se-polarization segagasi lokukhanya, ukuze ukukhanya okuyisiyingi kube ukukhanya kwe-elliptically polarized, bese kuba ukukhanya kwe-polarized linearly. ngokusebenzisa i-polarizer, futhi amandla okukhanya ayashintshwa.Ngalesi sikhathi, igagasi lokukhanya liqukethe ulwazi lomsindo futhi lisakazeka endaweni yamahhala.I-photodetector isetshenziselwa ukwamukela isignali ye-optical eguquliwe endaweni yokwamukela, bese ukuguqulwa kwesifunda kwenziwa ukuze kuguqulwe isignali ye-optical ibe isignali kagesi.Isignali yomsindo ibuyiselwa yi-demodulator, futhi ekugcineni ukuhanjiswa kwe-optical yesignali yomsindo kuqediwe.I-voltage esetshenziswayo iyisiginali yomsindo edluliswayo, okungaba ukuphuma kwerekhoda yomsakazo noma idrayivu ye-tape, futhi empeleni iyisiginali ye-voltage ehluka ngokuhamba kwesikhathi.
