Txuas lub router ua ntej.
Lub optical modem txuas nrog lub router ua ntej thiab tom qab ntawd mus rau qhov hloov, vim tias router xav tau faib ip, thiab qhov hloov pauv tsis tuaj yeem, yog li nws yuav tsum muab tso rau tom qab router.Yog hais tias tus password authentication yuav tsum tau, ntawm chav kawm, ua ntej txuas mus rau WAN chaw nres nkoj ntawm lub router, thiab tom qab ntawd txuas mus rau qhov hloov ntawm LAN chaw nres nkoj.
Lub teeb miv ua haujlwm li cas
Baseband modem yog tsim los ntawm kev xa, txais, tswj, interface, ua haujlwm vaj huam sib luag, fais fab mov thiab lwm qhov chaw.Cov ntaub ntawv davhlau ya nyob twg muab cov ntaub ntawv xa mus nyob rau hauv daim ntawv ntawm binary serial teeb liab, hloov nws mus rau hauv ib theem logic sab hauv los ntawm lub interface, thiab xa mus rau qhov xa mus, modulates nws mus rau hauv ib tug kab thov teeb liab los ntawm ib tug modulation Circuit Court, thiab xa. nws mus rau kab.Lub chaw txais tau txais cov teeb liab los ntawm kab, rov qab mus rau lub teeb liab digital tom qab lim dej, hloov pauv hloov pauv, thiab theem hloov dua siab tshiab, thiab xa mus rau cov khoom siv digital davhlau ya nyob twg.Optical modem yog ib yam khoom zoo ib yam li baseband modem.Nws txawv ntawm lub modem baseband.Nws txuas nrog rau cov kab hluav taws xob kho qhov muag thiab yog lub teeb liab kho qhov muag.
Qhov sib txawv ntawm optical modem, hloov thiab router
1. Cov haujlwm sib txawv
Kev ua haujlwm ntawm optical modem yog hloov lub teeb liab ntawm lub xov tooj mus rau hauv lub teeb liab ntawm lub network kab siv rau hauv lub computer hauv Internet;
Lub luag haujlwm ntawm lub router yog txuas ntau lub khoos phis tawj los ntawm lub network cable kom paub txog kev sib txuas virtual dial-up, cia li txheeb xyuas qhov xa cov ntaub ntawv thiab chaw nyob faib, thiab muaj lub luag haujlwm firewall.Ntawm lawv, ntau lub khoos phis tawj sib koom ib tus account broadband, Internet yuav cuam tshuam rau ib leeg.
Lub luag haujlwm ntawm kev hloov pauv yog txuas ntau lub khoos phis tawj nrog ib lub network cable kom paub txog kev ua haujlwm hauv Is Taws Nem ib txhij, tsis muaj lub luag haujlwm ntawm lub router.
2. Kev siv sib txawv
Thaum lub optical modem nkag mus rau qhov kho qhov muag fiber ntau hauv tsev, qhov hloov thiab router ua haujlwm ntawm LAN, tab sis qhov hloov ua haujlwm ntawm cov ntaub ntawv txuas txheej, thiab lub router ua haujlwm ntawm txheej txheej network.
3. Cov haujlwm sib txawv
Cias muab, qhov kho qhov muag modem yog sib npaug rau lub Hoobkas subassembly, lub router sib npaug rau cov khw muag khoom lag luam, thiab qhov hloov pauv yog sib npaug rau cov khoom xa khoom xa tuaj.Cov teeb liab analog kis tau los ntawm cov kab hluav taws xob zoo tib yam tau hloov mus rau hauv cov teeb liab digital los ntawm optical modem, thiab tom qab ntawd cov teeb liab xa mus rau PC los ntawm router.Yog hais tias tus xov tooj ntawm PCs tshaj qhov kev twb kev txuas ntawm router, koj yuav tsum tau ntxiv ib tug hloov mus rau nthuav lub interface.
Nrog rau kev txhim kho ntawm kev sib txuas lus fiber ntau optical, ib feem ntawm cov khoom siv kho qhov muag siv los ntawm cov neeg siv tam sim no muaj cov haujlwm ua haujlwm.
