Hokela router pele.
Modem ea optical e hokahantsoe le router pele ebe e hokahantsoe le switch, hobane router e hloka ho fana ka ip, 'me switch e ke ke ea khona, kahoo e tlameha ho beoa ka mor'a router. Haeba ho hlokahala netefatso ea phasewete, ehlile, qala ka ho hokela koung ea WAN ea router, ebe u hokela ho switch ho tsoa koung ea LAN.
Kamoo katse e bobebe e sebetsang kateng
Modem ea baseband e entsoe ka ho romela, ho amohela, ho laola, sebopeho, phanele ea ts'ebetso, phepelo ea motlakase le likarolo tse ling. Sesebelisoa sa terminal ea data se fana ka data e fetisitsoeng ka mokhoa oa lets'oao la binary serial, se le fetolela boemong ba logic ba kahare ka har'a interface, 'me se le romela karolong e romelang, se le fetola hore e be lets'oao la kopo ea mola ka potoloho ea modulation, 'me se le romela moleng. Yuniti e amohelang e amohela lets'oao ho tsoa moleng, e le khutlisetsa ho lets'oao la dijithale kamora ho sefa, ho fetola modulation e fapaneng, le phetoho ea boemo, 'me e le romela sesebelisoa sa terminal ea dijithale. Modem ea optical ke sesebelisoa se tšoanang le modem ea baseband. E fapane le modem ea baseband. E hokahane le mola o inehetseng oa fiber ea optical 'me ke lets'oao la optical.
Phapang pakeng tsa modem ea optical, switch le router
1. Mesebetsi e fapaneng
Mosebetsi oa modem ea optical ke ho fetola lets'oao la mohala oa thelefono hore e be lets'oao la mohala oa marang-rang bakeng sa ts'ebeliso ho Internet ea khomphutha;
Mosebetsi oa router ke ho hokahanya lik'homphieutha tse ngata ka thapo ea marang-rang ho etsa khokahano ea ho daela ka mokhoa oa sebele, ho khetholla ka bohona ho romelloa ha lipakete tsa data le kabo ea liaterese, 'me e na le ts'ebetso ea firewall. Har'a tsona, lik'homphieutha tse ngata li arolelana ak'haonte ea broadband, Inthanete e tla ama e 'ngoe le e 'ngoe.
Mosebetsi oa switch ke ho hokahanya lik'homphieutha tse ngata ka thapo e le 'ngoe ea marang-rang ho phethahatsa mosebetsi oa Inthanete ka nako e le 'ngoe, ntle le mosebetsi oa router.
2. Litšebeliso tse fapaneng
Ha modem ea optical e fihlella fiber ea optical lapeng, switch le router li sebetsa ho LAN, empa switch e sebetsa ho lera la khokahano ea data, 'me router e sebetsa ho lera la marang-rang.
3. Mesebetsi e fapaneng
Ha re bua ka bokhutšoanyane, modem ea optical e lekana le fektheri ea subassembly, router e lekana le morekisi oa thekiso e kholo, 'me switch e lekana le mofani oa thepa ea logistics. Letšoao la analog le fetisoang ka thapo e tloaelehileng ea marang-rang le fetoloa lets'oao la dijithale ke modem ea optical, ebe lets'oao le fetisoa ho PC ka router. Haeba palo ea li-PC e feta khokahano ea router, u hloka ho eketsa switch ho atolosa sebopeho.
Ka ntshetsopele ya puisano ya faeba ya optical, karolo ya di-modem tsa optical tse sebediswang ke basebetsi jwale di na le mesebetsi ya ho tsamaisa.
