Imodyuli yokubona sisixhobo sokuguqula isignali yombane, enokuthi ifakwe kwisixhobo se-transceiver yesignali yenethiwekhi efana neiirotha, iiswitshi, kunye nezixhobo zokuhambisa. Zombini iimpawu zombane kunye nezamehlo zizibonakaliso zamaza omlingo. Uluhlu lokuhanjiswa kweempawu zombane lulinganiselwe, ngelixa iimpawu ze-optical ziyakwazi ukuhanjiswa ngokukhawuleza nangaphezulu. Nangona kunjalo, ezinye izixhobo zangoku ziqaphela iimpawu zombane, ngoko kukho iimodyuli zokuguqula i-photoelectric.
Ngenxa ye-bandwidth ephezulu kunye nomgama omde wokuhanjiswa kwe-fiber optical transmission, ngelixa umgama wokuhanjiswa kwentambo yendabuko imfutshane kwaye ichaphazeleka ekuphazamisekeni kwe-electromagnetic, ukuze kwandiswe umgama wokudluliselwa konxibelelwano, i-fiber optical isetyenziselwa ukuhanjiswa. Ngokuthatha inxaxheba kwiimodyuli ze-optical, izibonakaliso zombane ziyakwazi ukuguqulwa zibe yimpawu ze-optical zokudluliselwa kwi-fibers optical, kwaye emva koko ziguqulelwe kwiimpawu ze-optical zibe iimpawu zombane eziza kufunyanwa ngezixhobo zenethiwekhi, ngaloo ndlela zandisa umgama wokudluliselwa konxibelelwano lwedijithali.
Umgaqo osebenzayo wemodyuli ye-optical ekupheleni kokudlulisa kukufaka isibonakaliso sombane ngesantya esithile sekhowudi ngokusebenzisa i-terminal yeminwe yegolide, kwaye emva koko uqhube i-laser ukuthumela isignali ye-optical kwizinga elihambelanayo emva kokuqhutyelwa yi-chip yomqhubi. ;
Umgaqo osebenzayo ekupheleni kokufumana kukuguqula isignali ye-optical efunyenweyo ibe ngumqondiso wombane ngokusebenzisa i-detector, kwaye emva koko uguqule isignali ekhoyo ebuthathaka efunyenweyo ibe ngumqondiso we-voltage nge-transimpedance amplifier, ngaloo ndlela ikhulisa umqondiso wombane, kwaye emva koko isuse i-overvoltage. umqondiso ngeamplifier enciphisayo. Isignali yamandla ombane aphezulu okanye aphantsi igcina umqondiso ophumayo wombane uzinzile.
