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).I-teknoloji ye-FTTx isuka kwi-ofisi ye-ofisi ephakathi kwigumbi lonxibelelwano lwengingqi ukuya kwi-terminal ye-terminal yomsebenzisi, kubandakanywa i-terminal optical line (OLT), i-optical network unit (ONU), i-terminal network optical (ONT).
Ngokwendawo ye-ONU ekupheleni komsebenzisi weyunithi yenethiwekhi ye-optical network, kukho ezininzi iintlobo ze-FTTx, ezinokuthi zihlulwe zibe yifayibha kwibhokisi yokutshintsha (FTTCab), ifayibha 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.I-ONU ibekwe kwibhokisi yesiphambuka.I-ONU engezantsi isebenzisa ucingo lobhedu okanye enye imidiya ukuxhuma 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 yenethiwekhi yamehlo (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.
