Ubuchwepheshe be-fibre-to-the-home (FTTH) bushintshe indlela esifinyelela ngayo i-inthanethi, buhlinzeka ngokuxhumana okusheshayo nokuthembekile kunanini ngaphambili. Enhliziyweni yalobu buchwepheshe kukhona ikhebula le-FTTH drop, ingxenye ebalulekile ekuletheni i-inthanethi esheshayo emakhaya nasemabhizinisini ngaphandle kokuphazamiseka. Kulo mhlahlandlela ophelele, sizohlola konke okudingeka ukwazi mayelana nezintambo ze-FTTH drop, kusukela ekwakhiweni kwazo nasekufakweni kwazo kuya ezinzuzweni zazo kanye nezinhlelo zokusebenza.
Iyini ikhebula lokudonsa le-FTTH?
Ikhebula lokudonsa le-FTTH, eyaziwa nangokuthi ikhebula lokudonsa le-fiber optic, ikhebula le-fiber optic elenzelwe ngqo ukuxhuma ama-terminal enethiwekhi ye-optical (ama-ONT) ezindaweni zababhalisile kumanethiwekhi e-fiber-to-the-home. Liyisixhumanisi sokugcina kunethiwekhi ye-FTTH, linikeza izinsizakalo ze-inthanethi ezisheshayo, ithelevishini kanye nocingo ngqo kubasebenzisi bokugcina.
Ukwakhiwa kwekhebula le-optical elingeniswa yi-FTTH
Izintambo zokudonsa ze-FTTH ngokuvamile zakhiwa yilungu lamandla eliphakathi elizungezwe yi-fiber optics kanye ne-sheath yangaphandle evikelayo. Ilungu lamandla eliphakathi linikeza amandla okudonsa adingekayo ekhebula ukuze limelane nokufakwa kanye nokucindezeleka kwemvelo, kuyilapho i-fiber optical ithwala isignali yedatha evela kumhlinzeki wesevisi iye endaweni yomsebenzisi. Ijazi langaphandle livikela ikhebula emswakama, emisebeni ye-UV nakwezinye izici zangaphandle, okuqinisekisa ukuthembeka nokusebenza kwesikhathi eside.
Ukufakwa kwekhebula le-optical le-FTTH elifakwa ngaphakathi
Ukufakwa kwezintambo ze-FTTH drop kuhilela izinyathelo eziningana ezibalulekile, okuhlanganisa ukuhambisa ikhebula lisuka endaweni yokusabalalisa liye endaweni yamakhasimende, ukuqeda i-fiber kuzo zombili izinhlangothi, nokuhlola uxhumano ukuqinisekisa ukusebenza okufanele. Kumelwe kuthathwe ukunakekelwa okukhethekile ngesikhathi sokufakwa ukuze kugwenywe ukugoba noma ukulimaza i-fiber ye-optical, njengoba lokhu kungonakalisa ukusebenza kwekhebula futhi kubangele ukulahleka kwesignali.
Izinzuzo zezintambo zokudonsa ze-FTTH
Izintambo zokulahla ze-FTTH inikeza izinzuzo eziningi ngaphezu kwezintambo zethusi zendabuko, kufaka phakathi umthamo we-bandwidth ophezulu, ukuncishiswa kwesignali okuphansi, kanye nokungavikeleki okukhulu ekuphazamisekeni kwe-electromagnetic. Lokhu kuzoholela ekuxhumekeni kwe-inthanethi okusheshayo nokuthembekile, ikhwalithi yezwi nevidiyo ethuthukisiwe, kanye nokuhlangenwe nakho okuthuthukisiwe komsebenzisi jikelele. Ngaphezu kwalokho, izintambo zokulahla ze-FTTH zihlala isikhathi eside futhi zidinga ukulungiswa okuncane kunezintambo zethusi, okwenza zibe yisisombululo esingabizi kakhulu nesivikela esikhathini esizayo sokuletha izinsizakalo ze-broadband ezisheshayo.
Ukusetshenziswa kwekhebula le-optical le-FTTH elingenisa
Izintambo ze-FTTH ezilahlayo zisetshenziswa ezinhlobonhlobo zezicelo kufaka phakathi izindawo zokuhlala, zezentengiselwano kanye nezezimboni. Ezindaweni zokuhlala, izintambo ze-FTTH ezilahlayo zinikeza ukufinyelela kwe-inthanethi okusheshayo, izinsizakalo ze-IPTV kanye ne-VoIP emakhaya ngamanye, kanti ezindaweni zezentengiselwano nezezimboni, zisekela izidingo zokuxhumana ezithuthukisiwe kanye nokuxhumana kwamabhizinisi nezinhlangano.
Ngamafuphi, izintambo ze-FTTH drop zidlala indima ebalulekile ekwenzeni kube lula ukwamukelwa kabanzi kobuchwepheshe be-fiber-to-the-home, zilethe izinsizakalo ze-inthanethi ezisheshayo nezinye ngqo kubasebenzisi bokugcina ngokusebenza okungenakuqhathaniswa nokuthembeka. Njengoba isidingo se-broadband esheshayo nethembekile siqhubeka nokukhula, izintambo ze-FTTH drop zizohlala ziyingxenye ebalulekile yengqalasizinda yesimanje yezokuxhumana, ziqhuba isizukulwane esilandelayo sokuxhumana kanye nokusungula izinto ezintsha zedijithali.
