Kwitekhnoloji yonxibelelwano yanamhlanje, ii-ONTs (i-Optical Network Terminals) kunye nee-router zizixhobo ezibalulekileyo, kodwa nganye idlala indima eyahlukileyo kwaye ifanelekile kwiimeko ezahlukeneyo zesicelo.Ngezantsi, siza kuxoxa ngomahluko phakathi kwezi zimbini kwiimeko zesicelo ukusuka kwimbono yobungcali, enomdla kwaye kulula ukuyiqonda.
Okokuqala, i-ONT inoxanduva ikakhulu lofikelelo lwenethiwekhi "emnyango".Xa i-optical fiber isuka kwigumbi lekhompyutha yalowo unxibelelana naye isiya kwikhaya okanye kwiofisi yakho, i-ONT “yi-translator” eguqula i-high-speed optical fiber signal ibe luphawu lwedijithali esinokuluqonda kwaye silusebenzise.Ngale ndlela, ikhompyuter yakho, ifowuni ephathwayo kunye nezinye izixhobo zinokuqhagamshela kwi-Intanethi kwaye zonwabele ilizwe ledijithali.
Umsebenzi ophambili we-ONT kukuguqula imiqondiso ye-optical kwimiqondiso yedijithali ekupheleni kwenethiwekhi yokufikelela.Ngokuqhelekileyo ifakwe ngaphakathi kwendawo yomsebenzisi (njengamakhaya, iiofisi, njl.) kwaye iqhagamshelwe ngokuthe ngqo kwisixhobo somsebenzisi.Ngoko ke, iimeko zokusetyenziswa kwe-ONT zigxininiswe kakhulu kwiindawo ze-fiber-to-the-home (FTTH), ezibonelela abasebenzisi ngeenkonzo zokufikelela kwi-Intanethi ezikhawulezayo nezizinzileyo.
I-router inokufaniswa "nengqondo" yenethiwekhi yekhaya okanye ishishini.Ayililo kuphela uxanduva lokudibanisa izixhobo ezininzi kwinethiwekhi, ikwamisela ukuba idatha kufuneka ivele phi kwaye kufuneka iye phi.Iiruthabanemisebenzi entsonkothileyo yomzila enokukhetha ngobulumko eyona ndlela yokuhambisa iipakethe zedatha ukusuka kwindawo yenethiwekhi ukuya kwenye ngokusekwe kwi-topology yothungelwano kunye neeprothokholi zonxibelelwano.Oku kufana nomphathi wetrafikhi okrelekrele onokuthi aqinisekise ukuba ukuhamba kwetrafikhi (iipakethi zedatha) kuthungelwano kuhamba kakuhle kwaye akuyi kubakho ukuxinana kwezithuthi (ukuxinana kwenethiwekhi).
Ukongezelela, i-router nayo inomsebenzi wokuguqulela idilesi yenethiwekhi (NAT), enokuguqula phakathi kweedilesi ze-IP zangasese kunye needilesi ze-IP zoluntu, ukubonelela abasebenzisi ngeendawo ezikhuselekileyo zenethiwekhi.Ngelo xesha, i-router inokulawula i-traffic yenethiwekhi kunye nokwabiwa kwe-bandwidth ukuqinisekisa ukuba isixhobo ngasinye sinokufumana izibonelelo zenethiwekhi ezaneleyo kwaye akuyi kubakho "ukubanjwa kwenethiwekhi".
Ngoko ke, iimeko zokusetyenziswa kwee-router zibanzi, azifanelekanga kuphela kuthungelwano lwasekhaya, kodwa zisetyenziswa ngokubanzi ezikolweni, kumashishini, kumaziko edatha kunye nezinye iindawo apho uxhulumaniso lwenethiwekhi, ulawulo nolawulo lufunekayo.
Isishwankathelo, umahluko ophambili kwiimeko zesicelo phakathi kwe-ONT kunye nee-routers kukuba i-ONT isetyenziselwa kakhulu kwiinethiwekhi zokufikelela kwi-fiber optical, ukuguqula iimpawu ze-optical kwiimpawu zedijithali, kunye nokubonelela abasebenzisi ngeenkonzo zokufikelela kwi-Intanethi ngokukhawuleza kunye nezinzile;ngelixa ii-routers zisetyenziselwa ukudibanisa kunye nokulawula izixhobo zenethiwekhi ezahlukeneyo, zibonelela ngokuzinza konxibelelwano lwenethiwekhi kunye nolawulo olusebenzayo lwenethiwekhi, kunye nokuqinisekisa ukuba idatha kwinethiwekhi inokudluliselwa ngokufanelekileyo nangokukhuselekileyo.
Imveliso yonxibelelwano yeCeiTaTechONT (ONU)ayinakusetyenziswa kuphela njengemveliso eguqula izibonakaliso ze-optical kwiimpawu zedijithali ukubonelela ngeenkonzo zokufikelela kwi-Intanethi ngokukhawuleza kunye nezinzile, kodwa ingasetyenziselwa njenge-router yokudibanisa nokulawula izixhobo zenethiwekhi ezahlukeneyo, ukubonelela uxhulumaniso oluzinzileyo lwenethiwekhi kunye nokusebenza okuphezulu.ulawulo lwenethiwekhi.Imveliso enye, ukusetyenziswa ezimbini.
