Isibuyekezo Mayelana ne-FTTH

I-FTTH (i-Fiber to the Home) ubuchwepheshe obuxhumanisa i-optical fiber nekhaya lomsebenzisi, obuthuthuke ngokushesha eminyakeni embalwa edlule futhi manje buyindlela eyinhloko yokufinyelela i-broadband emhlabeni jikelele.

Uma kuqhathaniswa nobuchwepheshe bendabuko bokufinyelela i-broadband njenge-DSL kanye ne-cable TV, i-FTTH ine-bandwidth ephezulu kanye ne-latency ephansi. Njengoba ijubane lokudlulisa le-optical fiber lishesha kakhulu kunele-copper wire kanye ne-coaxial cable, i-FTTH inganikeza ulwazi lwenethiwekhi oluzinzile nolusezingeni eliphezulu. Ngesikhathi esifanayo, i-FTTH iphinde isekele ukuxhumana okuqondiswayo okubili, okubonisa ukuthi inganikeza isivinini se-uplink esiphezulu kanye ne-downlink ngesikhathi esisodwa, okwanelisa kangcono izidingo zabasebenzisi zokulayisha nokulanda idatha.

Isimo sentuthuko ezifundeni ezahlukene zomhlaba singesendawo. Isifunda sase-Asia senze kahle ekuthuthukiseni ubuchwepheshe be-FTTH, amazwe anjengeJapan, iSouth Korea, neChina akhe amanethiwekhi amakhulu e-fiber optic. Isibonelo, iNingizimu Korea ifinyelele ukumbozwa kwe-FTTH kuzwelonke, njengoba amakhaya angaphezu kwamaphesenti angama-90 ethola izinsizakalo ze-broadband ezisheshayo. Ngokuphambene nalokho, intuthuko ye-FTTH eYurophu nase-United States ihlehlisiwe kakhulu, ikakhulukazi ngenxa yezindleko zokwakha eziphakeme kanye nokuvinjelwa kokuncintisana emakethe. Eminyakeni yamuva nje, i-FTTH ibilokhu ikhula ngokuthandwa emhlabeni jikelele. Ngokwezibalo, ngaphezu kwengxenye yesine yemindeni yomhlaba ixhunywe ku-fiber optics. Lo mkhuba uzoqhubeka nokusheshisa, futhi i-FTTH izosetshenziswa kabanzi futhi ithandwe kakhulu.

Esikhathini esizayo, ubuchwepheshe be-FTTH buzoqhubeka nokuguquka, futhi kunezindlela eziningana okufanele zibhekwe. Okokuqala ukwanda kwevidiyo enencazelo ephezulu kakhulu kanye neqiniso elibonakalayo (VR). Ngokuthandwa kwamavidiyo anencazelo ephezulu kakhulu njenge-4K kanye ne-8K, i-broadband evamile yehluleka ukufeza izidingo ze-bandwidth zabasebenzisi. I-bandwidth yesivinini esiphezulu se-FTTH izophenduka ingqalasizinda yokusekela izinhlelo zokusebenza zevidiyo ezinencazelo ephezulu kakhulu kanye ne-VR. Okwesibili, ukukhuphuka kwe-Intanethi Yezinto (IoT) kanye ne-5G kuzothuthukisa i-FTTH. I-Intanethi Yezinto ivele njengomkhuba obalulekile, ngenani elikhulayo lamadivayisi nezinhlelo zokusebenza ezidinga uxhumano. Ukufika kwe-5G kuzoletha izidingo ezengeziwe zokudlulisa idatha, kanti ukubambezeleka okuphansi kanye ne-bandwidth yesivinini esiphezulu se-FTTH kuzoba ingqalasizinda yesikhathi se-5G. Ngaphezu kwalokho, ngokukhuphuka kwe-cloud computing, inani elikhulayo lezinhlelo zokusebenza kanye nedatha lizothuthela efwini. Isivinini sokulayisha se-FTTH esisheshayo sizokwanelisa izidingo zabasebenzisi zokugcina amafu kanye nezinhlelo zokusebenza zamafu, kwakha uhlelo oluphelele lwe-cloud computing.

Ukuthuthukiswa kwe-FTTH kusabhekene nezinselele ezithile. Eyokuqala izindleko zokwakha. Izindleko zokwakha ze-FTTH ziphakeme kakhulu, ikakhulukazi ezindaweni ezinabantu abambalwa nezimo zezwe eziyinkimbinkimbi. Indlela yokunciphisa izindleko zokwakha nokwandisa ukumbozwa kwe-FTTH kuzoba yinkinga okufanele ixazululwe. Okwesibili, kukhona udaba lokuncintisana. Nakuba i-FTTH inezinzuzo ku-bandwidth kanye nokusebenza, abancintisana nabo njengabahlinzeki bekhebula kanye nabaqhubi beselula bahlala bethuthukisa isivinini sabo senethiwekhi kanye nekhwalithi yesevisi. Indlela yokugcina inzuzo yokuncintisana emakethe yokuncintisana kuyoba yinselele opharetha okudingeka babhekane nayo.
