Kubuchwepheshe besimanje bezokuxhumana, ama-ONT (Optical Network Terminals) namarutha kungamathuluzi abalulekile, kodwa ngayinye idlala indima ehlukene futhi ifanele izimo ezihlukene zohlelo lokusebenza. Ngezansi, sizoxoxa ngomehluko phakathi kwalokhu okubili kuzimo zohlelo lokusebenza kusukela kumbono wochwepheshe, othakazelisayo futhi okulula ukukuqonda.
Okokuqala, i-ONT inesibopho esikhulu sokufinyelela inethiwekhi "emnyango". Uma i-optical fibre isuka egumbini lekhompyutha yomsebenzisi wezokuxhumana iye ekhaya noma ehhovisi lakho, i-ONT "ingumhumushi" oguqula isignali yefiber optical enesivinini esikhulu ibe isignali yedijithali esingayiqonda futhi siyisebenzise. Ngale ndlela, ikhompuyutha yakho, umakhalekhukhwini kanye nezinye izisetshenziswa zingaxhumeka ku-inthanethi futhi zijabulele umhlaba wedijithali.
Umsebenzi oyinhloko we-ONT ukuguqula amasignali okukhanya abe amasignali edijithali ekupheleni kwenethiwekhi yokufinyelela. Ivamise ukufakwa ngaphakathi kwezakhiwo zomsebenzisi (njengamakhaya, amahhovisi, njll.) futhi ixhunywe ngokuqondile kumpahla yomsebenzisi. Ngakho-ke, izimo zohlelo lokusebenza lwe-ONT zigxile kakhulu endaweni ye-fiber-to-the-home (FTTH), ehlinzeka abasebenzisi ngezinsizakalo zokufinyelela ku-inthanethi ezishesha kakhulu nezizinzile.
Irutha ingafaniswa "nobuchopho" benethiwekhi yasekhaya noma yebhizinisi. Akukona nje kuphela ukuthi inesibopho sokuxhuma amadivayisi amaningi kunethiwekhi, futhi inquma ukuthi idatha kufanele ivele kuphi nokuthi kufanele iye kuphi.Amaruthazinemisebenzi eyinkimbinkimbi yomzila engakwazi ukukhetha ngobuhlakani indlela engcono kakhulu yokudlulisa amaphakethe edatha ukusuka endaweni eyodwa yenethiwekhi ukuya kwenye ngokusekelwe ku-topology yenethiwekhi kanye nezivumelwano zokuxhumana. Lokhu kufana nomkhuzi wethrafikhi ohlakaniphile ongaqinisekisa ukuthi ukuhamba kwethrafikhi (amaphakethe wedatha) kunethiwekhi kuhamba kahle futhi ngeke kube khona isiminyaminya (ukuminyana kwenethiwekhi).
Ngaphezu kwalokho, i-router nayo inomsebenzi wokuhumusha ikheli lenethiwekhi (NAT), engaguqula phakathi kwamakheli e-IP ayimfihlo namakheli e-IP omphakathi, inikeze abasebenzisi indawo evikelekile yenethiwekhi. Ngesikhathi esifanayo, i-router ingakwazi futhi ukuphatha ithrafikhi yenethiwekhi kanye nokwabiwa komkhawulokudonsa ukuze kuqinisekiswe ukuthi idivayisi ngayinye ingathola izinsiza zenethiwekhi ezanele futhi ngeke kube khona "ukubanjwa kwenethiwekhi".
Ngakho-ke, izimo zokusetshenziswa kwama-routers ziningi kakhulu, azifaneleki kuphela amanethiwekhi asekhaya, kodwa futhi zisetshenziswa kabanzi ezikoleni, amabhizinisi, izikhungo zedatha nezinye izindawo lapho kudingeka khona ukuxhumana kwenethiwekhi, ukuphathwa nokulawula.
Kafushane, umehluko omkhulu ezimeni zohlelo lokusebenza phakathi kwama-ONT namarutha ukuthi ama-ONT asetshenziselwa ikakhulukazi amanethiwekhi okufinyelela efiber optical, ukuguqula amasignali okukhanya abe amasignali edijithali, nokuhlinzeka abasebenzisi ngezinsizakalo zokufinyelela ku-inthanethi ezishesha kakhulu nezizinzile; kuyilapho amarutha esetshenziselwa ukuxhuma nokuphatha amadivaysi enethiwekhi ahlukene, ahlinzeke ngoxhumano lwenethiwekhi oluzinzile kanye nokuphathwa kwenethiwekhi okuphumelelayo, futhi aqinisekise ukuthi idatha kunethiwekhi ingadluliswa ngokushelela nangokuphephile.
Umkhiqizo wokuxhumana we-CeiTaTechI-ONT (ONU)ayikwazi ukusetshenziswa kuphela njengomkhiqizo oguqula amasignali optical abe amasignali edijithali ukuze unikeze izinsizakalo zokufinyelela ku-inthanethi ngesivinini esikhulu futhi ezinzile, kodwa futhi ingasetshenziswa njengendlela yomzila ukuxhuma nokuphatha amadivaysi enethiwekhi ahlukene, ukuhlinzeka ngoxhumano lwenethiwekhi oluzinzile nokusebenza kahle okuphezulu. ukuphathwa kwenethiwekhi. Umkhiqizo owodwa, ukusetshenziswa okubili.
