Emhlabeni osheshayo noqhutshwa ubuchwepheshe esiphila kuwo, isidingo se-inthanethi enesivinini siyaqhubeka nokuqhuma. Ngenxa yalokho, isidingo somkhawulokudonsa okhula njalo emahhovisi nasezindlini siba bucayi. Ubuchwepheshe be-Passive Optical Network (PON) kanye ne-Fiber-to-the-Home (FTTH) buye baba phambili ekuletheni isivinini se-inthanethi esishesha kakhulu. Lesi sihloko sihlola ikusasa lalobu buchwepheshe, sidingida intuthuko yabo engaba khona nezinselele.
Ukuvela kwe-PON/FTTH:
I-PON/I-FTTHamanethiwekhi asehambe ibanga elide kusukela asungulwa. Ukusatshalaliswa kwezintambo ze-fiber optic ngqo ezindlini nasemabhizinisini kuguqule ukuxhumana kwe-inthanethi. I-PON/FTTH inikeza isivinini esingenakuqhathaniswa, ukwethembeka kanye nomkhawulokudonsa ongenamkhawulo uma kuqhathaniswa nokuxhumana kwethusi okungokwesiko. Ukwengeza, lobu buchwepheshe buyakhula, bubenze bube ubufakazi besikhathi esizayo ukuze buhlangabezane nezidingo ezikhulayo zedijithali zabathengi namabhizinisi.
Intuthuko kubuchwepheshe be-PON/FTTH:
Ososayensi nonjiniyela bayaqhubeka nokuphusha imingcele yobuchwepheshe be-PON/FTTH ukuze bathole amazinga aphezulu okudluliswa kwedatha. Okugxilwe kakhulu ekuthuthukiseni amasistimu asebenza kahle kakhulu futhi angabizi kakhulu ukusekela ukukhula okunamandla kwethrafikhi ye-inthanethi. Enye yentuthuko enjalo ukuqaliswa kobuchwepheshe be-wavelength-division multiplexing (WDM), obuvumela ubude begagasi abaningi noma imibala yokukhanya ukuthi idluliselwe ngesikhathi esisodwa ngefayibha eyodwa yokubona. Lokhu kuphumelela kukhulisa kakhulu umthamo wenethiwekhi ngaphandle kokudinga ingqalasizinda eyengeziwe.
Ngaphezu kwalokho, ucwaningo luyaqhubeka lokuhlanganisa amanethiwekhi e-PON/FTTH anobuchwepheshe obusafufusa obufana namanethiwekhi eselula e-5G kanye namadivayisi we-inthanethi Yezinto (IoT). Lokhu kuhlanganiswa kuklanyelwe ukuhlinzeka ngoxhumano olungenazihibe, okuvumela ukudluliswa kwedatha okusheshayo nangcono kakhulu phakathi kwamadivayisi ahlukahlukene namasistimu afana nezimoto ezizimele, amakhaya ahlakaniphile nezinhlelo zokusebenza zezimboni.
Thuthukisa ukuxhumana kwemayela lokugcina:
Enye yezinselelo ngamanethiwekhi e-PON/FTTH ukuxhumeka kwemayela lokugcina, umlenze wokugcina wenethiwekhi lapho intambo ye-fiber optic ixhumeka ekhaya noma ehhovisi lomuntu. Le ngxenye ngokuvamile incike kungqalasizinda yethusi ekhona, ikhawulela amandla aphelele e-PON/FTTH. Imizamo iyaqhubeka yokushintsha noma ukuthuthukisa lolu xhumo lwemayela lokugcina nge-fiber optics ukuze kuqinisekiswe ukuxhumana okunesivinini esikhulu kuyo yonke inethiwekhi.
Ukunqoba izithiyo zezimali nezokulawula:
Ukusatshalaliswa okukhulu kwamanethiwekhi e-PON/FTTH kudinga ukutshalwa kwezimali okukhulu. Ingqalasizinda ingabiza ukuyimisa nokuyinakekela, ikakhulukazi ezindaweni zasemakhaya noma ezikude. Ohulumeni nabalawuli emhlabeni wonke bayakubona ukubaluleka kokufinyelela ku-inthanethi ngesivinini esikhulu ekukhuleni komnotho futhi baqalisa izinhlelo zokugqugquzela ukutshalwa kwezimali kwangasese kungqalasizinda ye-fiber optic. Ubambiswano lwezinkampani ezizimele kanye nezinhlelo zoxhaso ziyathuthukiswa ukuze kuvalwe igebe lezezimali futhi kusheshiswe ukunwetshwa kwamanethiwekhi e-PON/FTTH.
Izinkinga Zokuphepha Nobumfihlo:
Njenge-PON/I-FTTHamanethiwekhi aba ajwayelekile kakhulu, okuqinisekisa ukuvikeleka kanye nobumfihlo bedatha yomsebenzisi kuba yinto ehamba phambili. Njengoba ukuxhumana kukhula, kanjalo nethuba lokusatshiswa kwe-inthanethi nokufinyelela okungagunyaziwe. Abahlinzeki benethiwekhi nezinkampani zobuchwepheshe batshala imali ezinyathelweni eziqinile zokuphepha, ezihlanganisa ukubethela, izindonga zokuvikela umlilo kanye namaphrothokholi okuqinisekisa, ukuze kuvikelwe ulwazi lwabasebenzisi nokuvimbela ukuhlasela kwe-inthanethi.
Ekuphetheni:
Ikusasa lamanethiwekhi e-PON/FTTH liyathembisa, linikeza amandla amakhulu ukuhlangabezana nesidingo esikhulayo soxhumo lwe-inthanethi olunesivinini esikhulu. Ukuthuthuka kwezobuchwepheshe, ukuhlanganiswa nobuchwepheshe obusafufusa, ukuthuthukiswa kokuxhumana kwemayela lokugcina, nezinqubomgomo ezisekelayo konke kunomthelela ekwandiseni okuqhubekayo kwalawa manethiwekhi. Kodwa-ke, izinselele ezifana nezithiyo zezimali kanye nokukhathazeka ngokuvikeleka kufanele kubhekwane nazo ukuze kuqinisekiswe ukuzizwisa okungenazihibe nokuphephile kubasebenzisi. Ngemizamo eqhubekayo, amanethiwekhi e-PON/FTTH angaguqula ukuxhumana futhi aqhubekisele umphakathi, amabhizinisi nabantu ngabanye enkathini yedijithali.
