I-FTTH (ifayibha ekhayeni), akukho bantu baninzi abathetha ngayo ngoku, kwaye ayifumaneki rhoqo kwiindaba.
Hayi kuba kungekho xabiso, i-FTTH izise amakhulu ezigidi zeentsapho kuluntu lwedijithali; Hayi kuba ingenziwanga kakuhle, kodwa ngenxa yokuba yenziwe kakuhle kakhulu.
Emva kwe-FTTH, i-FTTR (ifayibha yegumbi) yaqala ukungena kwicandelo lombono. I-FTTR iye yaba sisisombululo esithandwayo sokunxibelelana ekhaya ngamava akumgangatho ophezulu, kwaye iyazifezekisa ngokwenene zonke iifayibha ze-optical zendlu. Inokubonelela ngamava okufikelela kwiGigabit kwigumbi ngalinye nakwikona nge-broadband kunye ne-Wi Fi 6.
Ixabiso le-FTTH libonakaliswe ngokupheleleyo. Ngokukodwa, i-COVID-19, eyaqhambuka kunyaka ophelileyo, ikhokelele ekubeni abantu bahlukaniswe kakhulu emzimbeni. Inethiwekhi ye-broadband yasekhaya esemgangathweni ophezulu ibe luncedo olukhulu emsebenzini, kubomi nasekonwabiseni kwabantu. Umzekelo, abafundi babengenakukwazi ukuya esikolweni ukuze bafunde. Nge-FTTH, babenokuthatha izifundo ezikwi-intanethi ezisemgangathweni ophezulu ukuqinisekisa inkqubela phambili yokufunda.
Ngaba ke i-FTTR iyimfuneko?
Enyanisweni, i-FTTH yanele ukuba usapho ludlale i-tiktok kwaye lufikelele kwi-intanethi. Nangona kunjalo, kwixesha elizayo, kuya kubakho izigcawu ezingaphezulu kunye nezicelo ezityebileyo zokusetyenziswa ekhaya, ezifana ne-teleconference, iiklasi ze-intanethi, ividiyo ye-4K / 8K ephezulu kakhulu, imidlalo ye-VR / AR, njl.njl., ezifuna amava aphezulu enethiwekhi, kwaye ukunyamezela iingxaki eziqhelekileyo ezifana ne-network jam, ukuhla kwefreyimu, i-asynchrony ye-audio-visual kuya kuba sezantsi nangaphantsi.
Njengoko sisazi, i-ADSL yanele ngo-2010. Njengolwandiso lwe-FTTH ngaphakathi kosapho, i-FTTR iza kuphucula ngakumbi iziseko ze-broadband ze-Gigabit fiber kwaye idale indawo entsha yemizi-mveliso engaphezulu kwe-trillion. Ukubonelela ngamava okufikelela kwi-Gigabit kwigumbi ngalinye nakwikona, umgangatho wentambo yenethiwekhi uye waba yingxaki ye-Gigabit endlwini yonke. I-FTTR ithatha indawo yentambo yenethiwekhi nge-optical fiber, ukuze i-optical fiber ikwazi ukusuka "ekhaya" ukuya "egumbini", kwaye isombulule ingxaki yentambo yenethiwekhi yasekhaya ngenyathelo elinye.
Inezibonelelo ezininzi:
I-fiber optical ibonwa njengeyona ndlela ikhawulezayo yokudlulisa isignali, kwaye akukho mfuneko yokuphucula emva kokusetyenziswa; Iimveliso ze-fiber optical zivuthiwe kwaye zingabizi, nto leyo enokonga iindleko zokusetyenziswa; Ubomi obude benkonzo ye-fiber optical; I-fiber optical ebonakalayo ingasetyenziswa, engayi konakalisa umhombiso wekhaya kunye nobuhle, njl.
Iminyaka elishumi ezayo ye-FTTR ifanelekile ukujongwa ngamehlo abomvu.
