(1) Umthombo wamakhodi nokuqopha
Imisebenzi emibili eyisisekelo: eyodwa iwukuthuthukisa ukusebenza kahle kokudluliswa kolwazi, okungukuthi, ngokusebenzisa uhlobo oluthile lobuchwepheshe bokubhala amakhodi ukuze uzame ukunciphisa inani lezimpawu ukunciphisa izinga lezimpawu. Okwesibili ukuqedela ukuguqulwa kwe-analog/digital (A/D), okungukuthi, lapho umthombo wolwazi unikeza isignali ye-analog, isifaki khodi somthombo siyiguqulela kusignali yedijithali ukuze kuzuzwe ukudluliswa kwedijithali kwesignali ye-analog.
(2) Ukubhala amakhodi kwesiteshi nokuqopha
Umsebenzi: Ukulawula iphutha. Isiginali yedijithali izothintwa umsindo namanye amaphutha enqubweni yokudlulisela. Ukuze kuncishiswe amaphutha, isifaki khodi sesiteshi kanye nesici solwazi oludlulisiwe sengeza izingxenye zokuvikela (izakhi zokuqondisa) ngokuvumelana nemithetho ethile ukuze kwakhiwe lokho okubizwa ngokuthi “ikhodi yokunqanda ukuphazamiseka”. Idikhoda yesiteshi ekugcineni ikhipha amakhodi ngokuvumelana nemithetho ephambene ehambisanayo ukuze ithole noma ilungise amaphutha futhi ithuthukise ukwethembeka kohlelo lokuxhumana.
(3) Ukubethela kanye nokubhala ngemfihlo
Ukuze kuqinisekiswe ukuvikeleka kolwazi oludlulisiwe, ukulandelana kwedijithali kuphazamiseka ngokuzenzakalelayo ukudluliselwa, okungukuthi, iphasiwedi yengezwe, le nqubo ibizwa ngokuthi ukubethela. Ukubuyisela umlayezo wangempela wukususa ukubethela.
(4) Ukushintshashintsha kwedijithali kanye nokwehliswa kwenani
Ukushintshashintsha kwedijithali: I-spectrum yefrikhwensi yesiginali ye-baseband yedijithali ihanjiswa kufrikhwensi ephezulu ukuze yakhe isignali yokuxhumana yebhendi elungele ukudluliselwa esiteshini. Ekupheleni kokwamukela, isiginali ye-baseband yedijithali ingabuyiswa ngokudilizwa okuhambisanayo noma ukwehliswa kokungahlangani.
(5) Ukuvumelanisa
Ukuvumelanisa: Kuwukugcina amasignali emikhawulweni yomibili yokwamukela nokwamukela ehambisana ngesikhathi, futhi kuyimfuneko yokuqinisekisa umsebenzi ohlelekile, onembile nothembekile wohlelo lokuxhumana lwedijithali.
Lena i-Shenzhen HDV phoelectron Technology Ltd. ukukulethela isihloko esithi “imodeli yesistimu yokuxhumana”, ngethemba ukukusiza,I-Shenzhen HDV phoelectron Technology Ltd. iwumkhiqizo okhethekile wabakhiqizi bemishini yezokuxhumana, imikhiqizo eshisayo yokuxhumana yenkampani yile:I-ONUuchungechunge, uchungechunge lwe-transceiver,OLTuchungechunge, kodwa futhi ukukhiqizwa uchungechunge module, ezifana: Ukuxhumana module optical, optical zokuxhumana module, inethiwekhi module optical, zokuxhumana module optical, optical fibre module, Ethernet optical fibre module, njll, anganikeza isevisi izinga elihambisana kubasebenzisi ezahlukene.
