Isakhiwo seukuxhumana opticalimojuli yethulwa
.
Ukuthuthukiswa kweukuxhumana opticalubuchwepheshe kanye nobuchwepheshe bolwazi kuyahambisana komunye nomunye, ngakolunye uhlangothi, amadivaysi okuxhumana optical athembele esakhiweni sokupakisha esinembayo ukuze afinyelele ukwethembeka okuphezulu kokuphuma kwamasignali optical, ukuze ubuchwepheshe bokupakisha obunembayo bamadivayisi okuxhumana optical buye baba ukhiye wokukhiqiza ubuchwepheshe ukuqinisekisa ukuthuthukiswa okusimeme nokusheshayo kwemboni yolwazi; Ngakolunye uhlangothi, ukuqamba okusha okuqhubekayo nokuthuthukiswa kobuchwepheshe bolwazi kuye kwabeka phambili izidingo eziphakeme zamadivayisi okuxhumana abonayo: izinga lokudlulisela okusheshayo, izinkomba zokusebenza okuphezulu, ubukhulu obuncane, idigri ephezulu yokuhlanganisa izithombe zikagesi, kanye nobuchwepheshe bokupakisha obunomnotho.

Isakhiwo sokupakisha samadivayisi okuxhumana optical siyahlukahluka, futhi ifomu lokupakisha elijwayelekile liboniswa esithombeni esingezansi. Ngenxa yokuthi ukwakheka nosayizi wamadivayisi okuxhumana okubona kuncane kakhulu (ububanzi obujwayelekile bomnyombo we-fiber yemodi eyodwa bungaphansi kuka-10μm), ukuchezuka kancane kunoma iyiphi indlela ngesikhathi sephakheji yokuhlanganisa kuzodala ukulahlekelwa okukhulu kokuhlanganisa. Ngakho-ke, ukuqondanisa kwamadivayisi okuxhumana abonakalayo namayunithi ahambayo ahlanganisiwe kudinga ukuba nokunemba kokuma okuphezulu. Esikhathini esedlule, idivayisi, ecishe ibe ngu-30cm x 30cm ngosayizi, yakhiwe izingxenye zokuxhumana ezisobala kanye nama-chips e-digital signal processing (DSP), futhi yenza izingxenye ezincane zokuxhumana okubonakalayo ngobuchwepheshe benqubo ye-silicon photonic, bese ihlanganisa amaphrosesa wesiginali yedijithali. eyenziwe inqubo ethuthukisiwe ye-7nm yokwenza ama-transceiver optical, kunciphisa kakhulu usayizi wedivayisi futhi kunciphise ukulahlekelwa kwamandla.

I-silicon photonicI-Optical Transceiveriyi-silicon evuthwe kakhuluidivayisi yezithombeokwamanje, okuhlanganisa ama-silicon chip processors okuthumela nokwamukela, ama-silicon photonic integrated chips ahlanganisa ama-lasemiconductor lasers, ama-optical splitters nama-signal modulators (Modulator), izinzwa zamehlo nama-fiber couplers nezinye izakhi. Ipakishwe kusixhumi se-fiber optic Esixhumekayo, isignali evela kuseva yesikhungo sedatha ingaguqulwa ibe isignali yokubona edlula ku-fiber.
