Isakhiwo seukuxhumana opticalimojuli yethulwa
.
Ukuthuthukiswa kweukuxhumana opticalubuchwepheshe kanye nobuchwepheshe bolwazi kuyahambisana nomunye, ngakolunye uhlangothi, amadivaysi okuxhumana optical ancike ukunemba ukupakisha isakhiwo ukuze kuzuzwe high-ukwethembeka okukhipha amasignali optical, ukuze ukunemba ukupakisha ubuchwepheshe amadivaysi zokuxhumana optical isibe ukhiye wokukhiqiza ubuchwepheshe ukuze kuqinisekiswe ukuthuthukiswa esimeme futhi ngokushesha imboni 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 esidlule, idivayisi, ecishe ibe ngu-30cm x 30cm ngosayizi, yakhiwe izingxenye zokuxhumana ezihlukene ze-optical kanye nama-chips we-digital signal processing (DSP), futhi yenza izingxenye ezincane zokuxhumana optical ngokusebenzisa ubuchwepheshe benqubo ye-silicon photonic, bese ihlanganisa amaphrosesa esignali yedijithali enziwe inqubo ethuthukisiwe ye-7nm ukwakha ama-transceiver optical, ukunciphisa kakhulu usayizi wedivayisi nokulahlekelwa 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.
