XPONimele i-X Passive Optical Network, isixazululo esisezingeni eliphezulu se-broadband esiguqule imboni yezokuxhumana.Ihlinzeka ngoxhumano lwe-inthanethi olushesha kakhulu futhi iletha izinzuzo eziningi kubahlinzeki besevisi nakubasebenzisi bokugcina.Kulesi sihloko, sizosusa i-XPON futhi sikuchaze konke odinga ukukwazi mayelana nalesi sixazululo se-broadband esisha.
I-XPON iwubuchwepheshe obusebenzisa amanethiwekhi okukhanya angenzi lutho ukuletha ukuxhumana kwe-broadband okunesivinini esikhulu emakhaya, amabhizinisi nezinye izikhungo.Isebenzisa i-optical fiber ukudlulisa idatha, amasignali ezwi nevidiyo ebangeni elide ngokulahleka okuncane nokusebenza kahle okukhulu.Ubuchwepheshe butholakala ngezinhlobonhlobo eziningi, okuhlanganisa i-GPON (Gigabit Passive Optical Network), i-EPON (Ethernet Passive Optical Network) ne-XG-PON (10 Gigabit Passive Optical Network), ngayinye inezici zayo ezithile nokusebenza kwayo.
Inzuzo enkulu ye-XPON isivinini sayo sokudlulisa idatha esimangalisayo.Nge-XPON, abasebenzisi bangajabulela uxhumo lwe-inthanethi olushesha kakhulu ukuze balande ngokushesha noma basakaze okuqukethwe kwe-multimedia enencazelo ephezulu, babambe iqhaza ekudlaleni kwe-inthanethi kwesikhathi sangempela, nokusingatha imisebenzi edinga idatha kalula.Lokhu kuzuzisa kakhulu amabhizinisi athembele kakhulu ekuxhumekeni kwe-inthanethi futhi adinga izixazululo ezinzile, ezisheshayo ze-broadband ukuze asekele imisebenzi yawo.
Ngaphezu kwalokho, amanethiwekhi e-XPON ayakwazi ukusekela izinombolo ezinkulu zabasebenzisi ngesikhathi esisodwa ngaphandle kokululaza ukusebenza.Lokhu kuyenza ilungele izindawo ezinabantu abaningi lapho izixazululo ze-broadband ezijwayelekile zingabhekana nokuminyana kanye nesivinini esihamba kancane ngezikhathi zokusetshenziswa okuphezulu.Nge-XPON, abahlinzeki besevisi bangahlangabezana kalula nesidingo esikhulayo se-inthanethi enesivinini futhi banikeze ulwazi lokuphequlula olungenazihibe kumakhasimende abo.
Ukwengeza, i-XPON ihlinzeka ngokuvikeleka okuthuthukisiwe nokuthembeka uma kuqhathaniswa nezixazululo zendabuko ze-broadband.Ngenxa yokuthi idatha idluliswa nge-fiber optics, kunzima kubageli be-inthanethi ukuthi babambe noma balawule isignali.Lokhu kuqinisekisa ukuthi ulwazi olubucayi olufana nokwenziwe ku-inthanethi noma idatha yomuntu siqu ihlala iphephile futhi ivikelekile.Ukwengeza, amanethiwekhi e-XPON asengozini encane yokuphazamiseka okuvela emithonjeni yangaphandle njengamagagasi kazibuthe kagesi noma izimo zezulu, aqinisekisa ukuxhumana kwe-inthanethi okungaguquki nokuthembekile.
Ukusungula inethiwekhi ye-XPON kudinga ukufakwa kwe-optical fibre, optical line terminal (OLT) kanye neyunithi yenethiwekhi yokubona (ONU).I-OLT itholakala ehhovisi elimaphakathi lomnikezeli wesevisi noma isikhungo sedatha futhi inomthwalo wemfanelo wokudlulisa idatha ku-ONU efakwe emagcekeni omsebenzisi.Izindleko zokuqala zokuqalisa zale ngqalasizinda zingaba phezulu kodwa zinganikeza izinzuzo ezibalulekile zesikhathi eside, njengezindleko eziphansi zokunakekela kanye nekhono lokuthuthukisa umthamo womkhawulokudonsa ngaphandle kokufaka indawo yonke inethiwekhi.
Ngokufigqiwe,XPONiyisixazululo sesimanjemanje se-broadband esiletha ukuxhumana kwe-inthanethi okushesha kakhulu emakhaya, amabhizinisi, nezinye izikhungo.Ngesivinini sayo sokudlulisa idatha esisheshayo esisheshayo, ikhono lokusekela izinombolo ezinkulu zabasebenzisi, ukuphepha okuthuthukisiwe nokuthembeka, i-XPON isibe yisinqumo sokuqala sabahlinzeki besevisi abafuna ukuhlangabezana nesidingo esikhulayo se-inthanethi enesivinini esikhulu.Ngokuqonda i-XPON nezinzuzo zayo, bobabili abahlinzeki besevisi nabasebenzisi bokugcina bangasebenzisa lobu buchwepheshe obusezingeni eliphezulu ukuze bavule amathuba amasha emhlabeni wedijithali.
