Isibhedlela esihlakaniphile inethiwekhi ye-All-optical network ehlanganisiwe yesixazululo sokuxhumana
Uhlelo lwenethiwekhi yesibhedlela ehlakaniphile ikakhulukazi luqukethe inethiwekhi yangaphandle (ihhovisi, i-inthanethi), inethiwekhi yangaphakathi (inethiwekhi yangasese yezokwelapha), kanye nenethiwekhi yokulawula (inethiwekhi yezisetshenziswa). Amanethiwekhi amathathu amakhulu anezinhlobo ezahlukene zebhizinisi. Kunethiwekhi yangaphakathi, iphethe idatha ebalulekile yezokwelapha. Ukuqinisekisa ukuvikeleka okuphelele, ukuhlukaniswa okuphelele ngokomzimba noma okunengqondo kuyadingeka. Ngesikhathi esifanayo, ngenxa yokuhlukahluka kwezinhlelo ezihlukahlukene zolwazi oluncane kanye nemishini esibhedlela, mayelana nokuthunyelwa kwezakhiwo zenethiwekhi, kubalulekile ukucabangela hhayi kuphela ukuguquguquka kwenethiwekhi kanye nezithiyo zesikhala, kodwa futhi isidingo sokubuyisela emuva izinhlekelele ngaphandle kwesizinda, kanye nokuba lula nokuba lula kokulungiswa kolayini benethiwekhi esikhathini esizayo.
Izidingo zokuthuthukisa. Yamukela isixazululo sokuxhumana esihlanganisiwe senethiwekhi yonke futhi ubeke umnyango wefiber optical ezigcemeni, ezindlini zokulala, eminyangweni, emagumbini enkomfa, amalabhorethri nezinye izindawo. Ngobuchwepheshe benethiwekhi ye-GPON, i-multiplexing ye-division yesikhathi noma i-wavelength division multiplexing ingasetshenziselwa ukuhlanganisa Amabhizinisi ahlukahlukene ahlanganiswe futhi adluliselwe ngaphakathi komugqa owodwa we-fiber optical ngaphandle kokuphazamisa omunye nomunye, okungagcini nje ukuhlangabezana nezidingo zokudlulisela isivinini esikhulu, umthamo omkhulu kanye nomkhawulokudonsa omkhulu. . Ngesikhathi esifanayo, ngenxa yokuthi inethiwekhi yonke ye-optical ithatha ukwakheka kwenethiwekhi yezingqimba ezimbili ze-OLT + ONU, i-architecture yenethiwekhi ilula futhi igcina isikhala sezintambo, futhi ingahlangabezana nezidingo zokuthuthukiswa kwenethiwekhi yesikhathi esizayo nge-bandwidth enkulu.
Isicelo sesixazululo
Ø Isivinini senethiwekhi esithuthukisiwe ukuze kuhlangatshezwane nezidingo zokudluliswa kwe-Gigabit yembobo eyodwa;
Ø Londoloza igumbi lekhompyutha nendawo yokufaka izintambo;
Ø Yehlisa ukutshalwa kwezimali kwenethiwekhi kanye nezindleko zokwakha, futhi yehlise izindleko zokulungisa kamuva kanye nezindleko zikagesi;
Ø Ifayibha eyodwa ngekamelo, ifayibha eyodwa ithwala izinsiza eziningi;
Ø Inethiwekhi kulula ukuyisebenzisa futhi ingathuthukiswa ngokushelelayo ngokuzayo;
Ø Wonke amatheminali ahlakaniphile, aphethwe yinkundla eyodwa, futhi kulula ukuwanakekela.
