Qhagamshela i-router kuqala.
Imodem ye-optical iqhagamshelwe kwi-router kuqala ize emva koko iqhagamshelwe kwiswitshi, kuba i-router kufuneka yabela i-ip, kwaye iswitshi ayinakukwazi, ngoko ke kufuneka ibekwe ngasemva kwe-router. Ukuba kuyimfuneko ukuqinisekiswa kwegama lokugqitha, ewe, qala ngokuqhagamshela kwi-port ye-WAN ye-router, uze uqhagamshelwe kwiswitshi evela kwi-port ye-LAN.
Indlela esebenza ngayo ikati elikhanyayo
Imodem ye-baseband yenziwe ngokuthumela, ukufumana, ukulawula, ujongano, iphaneli yokusebenza, umbane kunye nezinye iindawo. Isixhobo se-data terminal sinika idatha edluliselweyo ngendlela yesignali ye-binary serial, siyiguqula ibe yinqanaba le-logic yangaphakathi nge-interface, kwaye siyithumele kwinxalenye yokuthumela, siyiguqule ibe yisignali yesicelo somgca ngesekethe ye-modulation, kwaye siyithumele kumgca. Iyunithi yokwamkela ifumana isignali evela kumgca, iyibuyisele kwisignali yedijithali emva kokucoca, ukuguqula okuchaseneyo, kunye nokuguqulwa kwenqanaba, kwaye iyithumele kwisixhobo se-digital terminal. Imodem ye-optical sisixhobo esifana nemodem ye-baseband. Yahlukile kwimodem ye-baseband. Iqhagamshelwe kumgca ozinikeleyo we-optical fiber kwaye sisignali ye-optical.
Umahluko phakathi kwemodem ye-optical, iswitshi kunye ne-router
1. Imisebenzi eyahlukeneyo
Umsebenzi wemodem ye-optical kukuguqula isignali yomgca wefowuni ibe sisignali yomgca wenethiwekhi ukuze isetyenziswe kwi-intanethi yekhompyutha;
Umsebenzi we-router kukuqhagamshela iikhompyutha ezininzi ngentambo yenethiwekhi ukuze kubekho uqhagamshelo lwe-dial-up olubonakalayo, ukuchonga ngokuzenzekelayo ukuthunyelwa kweepakethi zedatha kunye nokwabiwa kweedilesi, kwaye unomsebenzi we-firewall. Phakathi kwazo, iikhompyutha ezininzi zabelana ngeakhawunti ye-broadband, i-intanethi iya kuchaphazelana.
Umsebenzi weswitshi kukuqhagamshela iikhompyutha ezininzi ngentambo enye yenethiwekhi ukuze kufezekiswe umsebenzi we-intanethi ngaxeshanye, ngaphandle komsebenzi we-router.
2. Iindlela ezahlukeneyo zokusetyenziswa
Xa imodem ye-optical ifikelela kwi-optical fiber ekhaya, iswitshi kunye ne-router zisebenza kwi-LAN, kodwa iswitshi isebenza kwi-data link layer, kwaye i-router isebenza kwi-network layer.
3. Imisebenzi eyahlukeneyo
Ngamafutshane, imodem ye-optical ilingana nomzi-mveliso we-subassembly, i-router ilingana nomthengisi othengisa ngobuninzi, kwaye iswitshi ilingana nomsasazi wezothutho. Isignali ye-analog edluliselwa ngentambo yenethiwekhi eqhelekileyo iguqulwa ibe yisignali yedijithali yimodem ye-optical, ize emva koko isignali idluliselwe kwiPC nge-router. Ukuba inani leePC lidlula uqhagamshelo lwe-router, kufuneka wongeze iswitshi ukuze wandise ujongano.
Ngophuhliso lonxibelelwano lwefayibha ye-optical, inxalenye yeemodem ze-optical ezisetyenziswa ngabaqhubi ngoku zinemisebenzi yokuhambisa idatha.
