Txhawm rau txiav txim siab seb lub cuab yeej yog ib qho qauv, tsis tas yuav muaj kev txhawj xeeb txog nws cov phiaj xwm, tsuas yog lees paub los ntawm lub davhlau ya nyob twg, thiab tib lub sijhawm hloov pauv rov qab ".
1. Fiber Modem (ONT / ONU)
Cov tub ntxhais tseem ceeb ntawm kev yoog mus rau lub cim hluav taws xob optical yog "demorical cov cim hluav taws xob": modulic cov cim hluav taws xob "
2. ADSL Modem
Nws yog modem uas siv lub siab - muaj ib feem ntawm cov kab xov tooj rau cov ntaub ntawv xa tawm, siv hauv kev dav dav hauv tsev. Nws tuaj yeem paub txog kev siv Is Taws Nem tsis muaj kev cuam tshuam nrog kev hu xov tooj, thiab yog qhov tsim nyog rau cov zej zog dav thiab cov chaw nyob deb nroog nyob qhov twg ntawm cov kab xov tooj tseem siv.
Haum rau cov xov tooj ib txwm muaj network kom paub cov kev hloov dua siab tshiab ntawm "digital teeb liab ↔ Xov Tooj Kab Analog teeb liab". Nws yog cov khoom siv tseem ceeb ntawm cov khoom dav dav thaum ntxov, xws li "hu}}} Cov ntaub ntawv xa xov tooj rau hauv xov tooj thiab nws yuav tsum txuas nrog lub khoos phis tawj lossis router.
3. CABLE MODEM
Kev sib kis teeb liab los ntawm cable TV Coaxial Cable tsis yog muaj kev sib xyaw ua ke ntau dua 10mbps, thiab cov neeg siv hluav taws xob, thiab cov neeg siv dav dav thiab cov neeg siv dav dav cia rau ntawm kab xaim hluav taws xob.
Nws yog qhov haum rau cable TV Coaxial cable tes hauj lwm kom paub txog kev hloov pauv ntawm "digital teeb liab ↔ co coaxial cable siab". Kev siv CABLE TV CABLE los xa cov cim TV thiab cov ntaub ntawv Broadband tib lub sijhawm muaj nyob rau hauv qee tsev neeg, thiab cov haujlwm yuav tsum tau los txhawb kev coot botfland.
{{0 {} g / 5g modem(nrog "Portable WiFi" Core Module)
Los ntawm lub tsev ua - hauv 4g / 5g kev sib txuas lus pom (NT Nyob rau tib lub sijhawm, lub cim ntsuas digital ntawm lub davhlau ya nyob twg (khoos phis tawj) yog "hloov kho" wireless teeb liab ↔ digital kos npe ".
Cia siab rau ntawm cellular networks, 4G lossis 5g txawb chaw nres tsheb cov teeb liab, thiab tuaj yeem muab cov khoom siv network tsis muaj fiber ntau
5. Lora / NB - io iot modem
Cov tub ntxhais ntawm kev yoog raws li lora qis - kev sib kis ntawm cov xov tooj cua ntawm i} Tus ip Kev hloov dua tshiab ntawm "Lora teeb liab ↔ rau digital teeb liab" hauv point- rau {{}}}}}} point point point point scen. Nws yog feem ntau siv rau iot cov khoom siv xws li ntse meters (dej meters, hluav taws xob meters) thiab cov hluav taws xob ib puag ncig uas tsis tas yuav kis tau zoo.
Nb {- iOt modem yog yoog raws li cov neeg ua haujlwm i6 Tus neeg teb xov tooj lub hauv paus pib, thiab tom qab ntawd "rau hauv lub cim digital, uas haum rau cov ntaub ntawv me me, xws li chaw nres tsheb ntse thiab cov cuab yeej taug kev.
6. Plc modem
Fais fab kab modem (plc modem) siv lub tsev / cov kab ke sib kis tau los ntawm kev hloov pauv nruab nrab ntawm "cov hluav taws xob sib kis. Lub teeb liab digital yog thauj mus rau 220V / 380V lub zog hluav taws xob los ntawm kev ua haujlwm digital los ntawm demodulation ntawm lwm qhov kawg ntawm tib lub zog voj, ua kom muaj kev sib txuas nrog yam tsis muaj hluav taws xob ntxiv.
7. Satemite Modem
The digital signal of the terminal is "modulated" into radio frequency signals suitable for satellite transmission, such as Ku-band and Ka-band signals, and sent to communication satellites through satellite antennas. Nyob rau tib lub sijhawm, lub xov tooj cua hauv xov tooj cua tau xa mus los ntawm lub satellite tau txais kev xa mus rau lub cim digital rau kev hloov pauv ntawm "cov xov tooj cua Satellite ntsuas".
Nws yog siv nyob rau hauv dej hiav txwv - mus Nkoj Kev Tshawb Fawb, thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb, xws li Kev Tshawb Fawb Txog Kev Tshawb Fawb, thiab cov ntaub ntawv xa khoom los ntawm lub tshuab satellite.
2 hom khoom siv no uas tsis xa mus rau Modem
Txawm li cas los xij, tib neeg tau nkag siab yooj yim raws li lawv tsis muaj txoj haujlwm tseem ceeb ntawm "Modem".
1.wireless router / wifi router:Nws yog tsuas yog lub luag haujlwm rau "network faib tawm" (faib cov khoom siv hluav taws xob uas muaj zog los siv nws cov xov tooj / Weding / Weding / wirit)
2.Switch:Nws yog tsuas yog lub luag haujlwm rau "nthuav dav network chaw nres nkoj", tsis muaj teeb meem hloov dua siab tshiab network rau ntau lub zog network, tsis muaj teeb meem hloov dua siab tshiab?
