Ukukhetha okulungileIkhebula lokudonsa le-FTTHkuqinisekisa ukuthi uxhumano lwakho lwefayibha lusebenza kahle. Kungakhathaliseki ukuthi udinga i-ikhebula lokudonsa le-FTTH langaphandle, aikhebula le-fiber optic elingeyona insimbi, nomaikhebula le-fiber optic elingaphansi komhlaba, ukuqonda izinketho zakho kubalulekile. Lezi zintambo zakha umgogodla weikhebula le-fiber optic le-FTTHukufakwa, okuletha isivinini kanye nokuqina.
Izinto Ezibalulekile Okufanele Uzicabangele
- Ukukhetha ikhebula elifanele le-FTTH kubalulekile ukuze kube ne-inthanethi enhle. Cabanga ngesimo sezulu nokuthi lizofakwa kanjani. Lokhu kusiza ukuthi lihlale lisebenza kahle isikhathi eside.
- Izintambo zokudonsa ze-FTTH ezenziwe ngaphambilini ziyatholakalakulula ukukusetha. Abadingi ukuxhunywa, okusindisa isikhathi futhi kwenza izinto zibe lula. Lokhu kuhle kakhulu ekusethweni okusheshayo.
- Izintambo eziqinile zibalulekileKhetha lezo ezingamelana nesimo sezulu esinzima. Izintambo ezivikelwe noma ze-ADSS zisebenza kahle ezimweni ezinzima ukugcina inethiwekhi yakho isebenza.
Ukuqonda Amakhebula E-FTTH Drop
Ziyini Izintambo Zokulahla ze-FTTH
Izintambo zokudonsa ze-FTTH ziyizintambo ezikhethekile ze-fiber optic ezenzelwe uxhumano "lwemayela lokugcina" kumanethiwekhi e-fiber-to-the-home (FTTH). Lezi zintambo zixhumanisa indawo yokusabalalisa eyinhloko emakhaya noma ezakhiweni ngazinye, okuqinisekisa ukudluliswa kwedatha okungenamthungo nokuthembekile. Isakhiwo sazo sihlanganisa izingxenye ezintathu eziyinhloko:
- Ilungu eliphakathi lamandla elinikeza amandla okudonsa.
- Imicu ye-optical ephatha ukudluliswa kwedatha okusheshayo.
- Igobolondo langaphandle elivikelayo elivikela umswakama kanye nokuchayeka emisebeni ye-UV.
Ngokuvamile, izintambo ze-FTTH drop ziqukethe imicu engu-1 kuya ku-4, okwenza zibe zincane futhi ziguquguquke kakhulu. Usayizi wazo omncane kanye nemicu engazweli ukugoba kuvumelaukufakwa okulula, ngisho nasezindaweni eziqinile noma eziyinkimbinkimbi. Ungafaka lezi zintambo emoyeni, ngaphansi komhlaba, noma ngokungcwaba ngqo, kuye ngezidingo zakho ezithile. Zitholakala ngezinguqulo eziqediwe kusengaphambili noma ngaphandle kwezixhumi, zinikeza ukuguquguquka kwezimo ezahlukene zokufakwa.
Kungani Zibalulekile
Izintambo zokulahla ze-FTTH zidlala i-indima ebalulekile ekuletheniI-inthanethi esheshayo kanye nokuxhumeka okuthembekile emakhaya nasemabhizinisini. Ngokungafani nezinye izintambo ze-fiber optic, zenzelwe ngqo ukumelana nezinselele zemvelo ngenkathi zigcina ukusebenza kahle. Ukwakhiwa kwazo okuqinile kuqinisekisa ukuqina ezimweni ezahlukahlukene, kungakhathaliseki ukuthi zifakwe ngaphansi komhlaba noma zichayeke ezintweni ezisetshenziswa emoyeni.
Lezi zintambo zibalulekile ekuvaleni igebe phakathi kwenethiwekhi eyinhloko nabasebenzisi bokugcina. Ukuguquguquka kwazo kanye nobukhulu bazo obuncane kuzenza zilungele ukufakwa kwasemadolobheni nasemaphandleni ngokufanayo. Ezindaweni zasemadolobheni, ukufakwa komhlaba kuvamile ngenxa yengqalasizinda ekhona, kuyilapho ukuthunyelwa kwasemakhaya kuvame ukuthembela ezindleleni zasemoyeni ukunciphisa izindleko. Kungakhathaliseki ukuthi kuhlelwe kanjani, izintambo zokudonsa ze-FTTH ziqinisekisa ukuthi ukuxhumana kokugcina nomsebenzisi kusebenza kahle futhi kuthembekile.
Izinhlobo Zezintambo Zokulahla ze-FTTH
Izintambo Zokulahla Eziphansi
Izintambo eziphansi zokudonsa ziyisinqumo esithandwayoUkufakwa kwe-FTTHngenxa yokwakheka kwazo okulula nokuncane. Lezi zintambo kulula ukuzifaka, ikakhulukazi ezindaweni zokuhlala lapho isikhala silinganiselwe khona. Isakhiwo sazo esiphansi siqinisekisa ukuthi zihlangana kahle nendawo ezungezile, zigcina ubuhle ngenkathi ziletha ukuxhumana okusebenzayo.
Izinzuzo ezibalulekile zezintambo eziwela phansi zifaka:
