Qhagamshela irutha kuqala.
Imodem ye-optical ixhunywe kwi-router kuqala kwaye emva koko itshintshe, kuba i-router idinga ukwaba ip, kwaye umtshini awukwazi, ngoko kufuneka ubekwe emva komzila.Ukuba ukuqinisekiswa kwegama lokugqitha kuyafuneka, ngokuqinisekileyo, qale uqhagamshele kwi-WAN port ye-router, uze uqhagamshele kwi-switch evela kwi-LAN port.
Isebenza njani ikati ekhaphukhaphu
Imodem ye-baseband yenziwe ngokuthumela, ukufumana, ukulawula, ujongano, iphaneli yokusebenza, ukunikezelwa kwamandla kunye nezinye iindawo.Isixhobo se-terminal yedatha sibonelela ngedatha egqithisiweyo ngohlobo lwesiginali ye-binary serial, iyiguqulela kwinqanaba le-logic yangaphakathi ngojongano, kwaye iyithumele kwindawo yokuthumela, iyimodareyitha ibe ngumqondiso wesicelo somgca ngesekethe yohlengahlengiso, kwaye ithumela. ukuya emgceni.Iyunithi yokufumana ifumana isignali kumgca, ibuyisela kwisignali yedijithali emva kokucoca, ukumodareyitha okuphambeneyo, kunye nokuguqulwa kwenqanaba, kwaye uyithumele kwisixhobo se-terminal yedijithali.Imodem yokubona sisixhobo esifana nemodem yebhendi.Yahlukile kwimodem ye-baseband.Idityaniswe kumgca onikezelweyo wefiber optical kwaye iluphawu lokukhanya.
Umahluko phakathi kwemodem ye-optical, tshintsha kunye ne-router
1. Imisebenzi eyahlukeneyo
Umsebenzi wemodem ye-optical kukuguqula isignali yomgca wefowuni ibe ngumqondiso womgca womnatha wokusetyenziswa kwi-Intanethi yekhompyutheni;
Umsebenzi we-router kukudibanisa iikhomputha ezininzi ngentambo yenethiwekhi ukuze uqaphele uxhulumaniso lwe-dial-up virtual, ukuchonga ngokuzenzekelayo ukuthunyelwa kweepakethi zedatha kunye nokwabiwa kwedilesi, kwaye inomsebenzi we-firewall.Phakathi kwabo, iikhomputha ezininzi zabelana nge-akhawunti ye-broadband, i-Intanethi iya kuchaphazela enye kwenye.
Umsebenzi wokutshintsha kukudibanisa iikhomputha ezininzi kunye nentambo yenethiwekhi enye ukuqonda umsebenzi we-Intanethi ngaxeshanye, ngaphandle komsebenzi we-router.
2. Ukusetyenziswa okwahlukeneyo
Xa imodem ye-optical ifikelela kwi-fiber optical ekhaya, i-switch kunye ne-router isebenza kwi-LAN, kodwa i-switch isebenza kwi-data link layer, kwaye i-router isebenza kwi-network layer.
3. Imisebenzi eyahlukeneyo
Ukubeka nje, imodem ye-optical ilingana nefektri ye-subassembly, i-router ilingana nomthengisi we-wholesale, kwaye utshintsho lulingana nomthengisi wezinto eziphathekayo.Umqondiso we-analog ohanjiswe ngentambo yenethiwekhi eqhelekileyo iguqulwa ibe ngumqondiso wedijithali yimodem ye-optical, kwaye emva koko isibonakaliso sidluliselwa kwi-PC nge-router.Ukuba inani leePC lidlula uxhulumaniso lwe-router, kufuneka udibanise iswitshi ukwandisa i-interface.
Ngophuhliso lonxibelelwano lwefiber optical, inxalenye yeemodem ze-optical ezisetyenziswa ngabaqhubi ngoku zinemisebenzi yomzila.
