Isakhiwo seukuxhumana okubonakalayoimodyuli yethulwa
Ukuthuthukiswa kweukuxhumana okubonakalayoubuchwepheshe kanye nobuchwepheshe bolwazi kuyahambisana, ngakolunye uhlangothi, amadivayisi okuxhumana okubonakalayo athembele esakhiweni sokupakisha esinembile ukuze kufezwe umphumela othembekile wezibonakaliso zokukhanya, ukuze ubuchwepheshe bokupakisha obunembile bamadivayisi okuxhumana okubonakalayo bube ubuchwepheshe obubalulekile bokukhiqiza ukuqinisekisa intuthuko esimeme futhi esheshayo yomkhakha wolwazi; Ngakolunye uhlangothi, ukusungula izinto ezintsha okuqhubekayo kanye nentuthuko yobuchwepheshe bolwazi kubeke phambili izidingo eziphakeme zamadivayisi okuxhumana okubonakalayo: izinga lokudlulisa elisheshayo, izinkomba zokusebenza eziphakeme, ubukhulu obuncane, izinga eliphezulu lokuhlanganiswa kwe-photoelectric, kanye nobuchwepheshe bokupakisha obungabizi kakhulu.
Isakhiwo sokupakisha samadivayisi okuxhumana kwe-optical siyahlukahluka, futhi ifomu lokupakisha elijwayelekile liboniswe esithombeni esingezansi. Ngenxa yokuthi isakhiwo nosayizi wamadivayisi okuxhumana kwe-optical kuncane kakhulu (ububanzi obujwayelekile be-core fiber yemodi eyodwa bungaphansi kuka-10μm), ukuphambuka okuncane kunoma iyiphi indlela ngesikhathi sephakheji yokuhlanganisa kuzobangela ukulahlekelwa okukhulu kokuhlanganisa. Ngakho-ke, ukuvumelanisa kwamadivayisi okuxhumana kwe-optical namayunithi ahambisanayo ahambisanayo kudinga ukuba nokunemba okuphezulu kokubeka. Esikhathini esidlule, idivayisi, enobukhulu obungaba ngu-30cm x 30cm, yakhiwe izingxenye zokuxhumana ze-optical ezihlukile kanye nama-chip okucubungula isignali yedijithali (DSP), futhi yenza izingxenye ezincane zokuxhumana kwe-optical ngokusebenzisa ubuchwepheshe benqubo ye-silicon photonic, bese ihlanganisa amaprosesa esignali yedijithali enziwe yinqubo ethuthukisiwe ye-7nm ukwakha ama-transceivers e-optical, kunciphisa kakhulu usayizi wedivayisi futhi kunciphisa ukulahleka kwamandla.
I-silicon photonicI-Transceiver Yokubonaiyi-silicon evuthiwe kakhuluidivayisi ye-photonicokwamanje, kufaka phakathi amaprosesa e-silicon chip okuthumela nokwamukela, ama-silicon photonic integrated chips ahlanganisa ama-semiconductor lasers, ama-optical splitters nama-signal modulators (Modulator), ama-optical sensors nama-fiber couplers nezinye izingxenye. Ipakishwe kusixhumi se-fiber optic esixhunywayo, isignali evela kuseva yesikhungo sedatha ingaguqulwa ibe isignali ye-optical edlula ku-fiber.
