Yini i-FTTx?
I-FTTx ithi “Fiber To The x” futhi yitemu elivamile lokufinyelela ifayibha kwezokuxhumana ze-fiber optic. x imele indawo yomugqa wefayibha. Okufana nokuthi x = H (Ifayibha Eya Ekhaya), x = O (Ifayibha Ehhovisi), x = B (I-Fiber eya Esakhiweni). Ubuchwepheshe be-FTTx busukela emishinini yehhovisi emaphakathi egumbini lezokuxhumana lesifunda kuya ezintweni ezisetshenziswayo, okuhlanganisa netheminali ye-optical line (OLT), iyunithi yenethiwekhi yokubona (I-ONU), itheminali yenethiwekhi yokubona (ONT).
Ngokusho kwendawo ye-I-ONUekugcineni komsebenzisi weyunithi yenethiwekhi ye-optical, kunezinhlobo eziningi ze-FTTx, ezingahlukaniswa zibe i-fibershintshaibhokisi (FTTCab), i-fiber eceleni komgwaqo (FTTC), i-fiber eya esakhiweni (FTTB), i-fiber eya ekhaya (FTTH), i-fiber Ehhovisi (FTTO) namanye amafomu esevisi. I-opharetha yase-US i-Verizon ibhekisela ku-FTTB ne-FTTH njengefayibha ezakhiweni (FTTP).
I-FTCab(I-Fiber KuKhabhinethi）
Ikhebula lendabuko lithathelwa indawo nge-fiber optical. II-ONUibekwe ebhokisini lokuhlangana. II-ONUngezansi kusetshenziswa intambo yethusi noma enye imidiya ukuxhuma kumsebenzisi.
I-FTTC(I-Fiber Ku-Curb）
Ukufakwa kanye nokusetshenziswa kwezintambo ezibonakalayo ukusuka ehhovisi elimaphakathi ukuya emigwaqweni engaphakathi kwamamitha ayinkulungwane amakhaya noma amahhovisi. Ngokuvamile, isixhumanisi esingaba khona sokudlulisa i-broadband esiseduze kakhulu nomsebenzisi sibekwe kuqala. Uma kunesidingo sezinsizakalo ze-broadband, i-fiber ingalethwa ngokushesha kumsebenzisi futhi i-fiber ingafinyelelwa ekhaya.
I-FTTB(I-Fiber eya esakhiweni)
Kuyindlela yokufinyelela ye-broadband esekelwe kubuchwepheshe benethiwekhi ye-optical fibre network. Isebenzisa ifayibha esakhiweni nentambo yenethiwekhi ukuya ekhaya ukuze kuzuzwe ukufinyelela kwebroadband yomsebenzisi. Ngokuvamile, kusetshenziswa ukufinyelela kolayini okuzinikele, okulula ukukufaka futhi kunganikeza izinga eliphezulu elikhuphuka nomfula elingaphansi kuka-10Mbps (okukhethekile).
I-FTTH(I-Fiber Yasekhaya）
I-TTH isho ukufakwa kweyunithi yenethiwekhi yokubona (I-ONU) kumsebenzisi wasekhaya noma umsebenzisi webhizinisi. Iwuhlobo lohlelo lokusebenza lwenethiwekhi yokufinyelela okubonakalayo eliseduze kakhulu nomsebenzisi ngaphandle kwe-FTTD (i-fiber optical to desktop) ochungechungeni lokufinyelela okubonakalayo. Ubuchwepheshe be-PON sebuphenduke indawo enkulu okwabelwana ngayo abaqhubi be-broadband bomhlaba wonke futhi bubhekwa njengesinye sezixazululo ezingcono kakhulu zobuchwepheshe zokufeza i-FTTH.
I-FTTP(I-Fiber Ku-Premise）
I-FTTP yitemu laseNyakatho Melika. Ihlanganisa i-FTTB, i-FTTC, ne-FTTH ngomqondo omncane, futhi inweba izintambo ze-fiber optical ezindlini noma kumabhizinisi.
