Lapho i-voltage yengezwa ekristaluni ye-electro-optic, inkomba ye-refractive nezinye izici zokukhanya zokushintsha kwekristalu, shintsha isimo se-polarization segagasi lokukhanya, ukuze ukukhanya okuyisiyingi kube ukukhanya kwe-elliptically polarized, bese kuba ukukhanya kwe-polarized ngokusebenzisa i-polarizer, futhi ukuqina kokukhanya kuyashintshwa. 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.
