Yintoni FTTx?
I-FTTx yi "Fiber To The x" kwaye ligama eliqhelekileyo lokufikelela kwifayibha kunxibelelwano lwefiber optic. x imele indawo yomgca wefiber. Enjenge-x = H (IFayibha ukuya eKhaya), x = O (Ifayibha kwi-Ofisi), x = B (IFayibha kwiSakhiwo). Itekhnoloji yeFTTx iqala kwisixhobo se-ofisi esembindini kwigumbi lonxibelelwano lwengingqi ukuya kwisixhobo somsebenzisi wetheminali, kubandakanywa i-terminal ye-optical line (OLT), iyunithi yenethiwekhi yamehlo (I-ONU), i-terminal yenethiwekhi ye-optical (ONT).
Ngokwendawo yeI-ONUekupheleni komsebenzisi weyunithi yenethiwekhi yamehlo, kukho iintlobo ezininzi zeFTTx, ezinokohlulwa zibe yifayibha ukuyatshintshaibhokisi (FTTCab), ifayibha ukuya ecaleni kwendlela (FTTC), ifayibha kwisakhiwo (FTTB), ifayibha ukuya ekhaya (FTTH), ifayibha Kwiofisi (FTTO) kunye nezinye iifom zenkonzo. Umsebenzisi wase-US uVerizon ubhekisa kwi-FTTB kunye ne-FTTH njengosinga kwizakhiwo (FTTP).
FTCab(IFayibha kwiKhabhinethi）
Ikhebula lemveli litshintshwa ngefiber optical. II-ONUibekwe kwibhokisi yesiphambuka. II-ONUngezantsi isebenzisa ucingo lobhedu okanye enye imidiya ukuqhagamshela kumsebenzisi.
I-FTTC(IFayibha ukuya kwiCurb）
Ukufakwa kunye nokusetyenziswa kweentambo ze-optical ukusuka kwiofisi ephakathi ukuya kwiindlela ezingaphakathi kwewaka leenyawo zamakhaya okanye iiofisi. Ngokubanzi, ikhonkco losasazo lwebroadband elinokubakho elikufutshane kakhulu kumsebenzisi libekwe kuqala. Emva kokuba kukho imfuneko yeenkonzo ze-broadband, i-fiber inokukhokelela ngokukhawuleza kumsebenzisi kwaye i-fiber inokufikelelwa ekhaya.
I-FTTB(IFayibha ukuya kwisakhiwo)
Yindlela yokufikelela kwibroadband esekwe kubuchwephesha benethiwekhi yefiber optical. Isebenzisa ifayibha kwisakhiwo kunye nentambo yothungelwano ukuya ekhaya ukuphumeza ukufikelela komsebenzisi kwibroadband. Ngokuqhelekileyo, ukufikelela kumgca ozinikeleyo kusetyenziswa, ekulula ukuyifaka kwaye kunokubonelela ngomlinganiselo ophezulu kunye nomgangatho ophantsi we-10Mbps (odwa).
I-FTTH(IFayibha ukuya eKhaya）
I-TTH ibhekisa kufakelo lweyunithi yomsebenzi womnatha obonakalayo (I-ONU) kumsebenzisi wasekhaya okanye umsebenzisi weshishini. Luhlobo lwesicelo senethiwekhi yokufikelela kwi-optical ekufutshane kumsebenzisi ngaphandle kwe-FTTD (i-fiber optical to desktop) kuluhlu lokufikelela kwi-optical access. Itekhnoloji ye-PON iye yaba yindawo ephambili ekwabelwana ngayo ngabaqhubi be-broadband behlabathi kwaye ithathwa njengenye yezona zisombululo zobugcisa zokufikelela kwi-FTTH.
I-FTTP(IFayibha ukuya kwindawo）
I-FTTP ligama laseMntla Melika. Ibandakanya i-FTTB, i-FTTC, kunye ne-FTTH ngengqiqo emxinwa, kwaye yandisa iintambo zefiber optical kumakhaya okanye kumashishini.
