Cov hom fiber ntau Media Converters (Kuv yuav sau nws li MC hauv qab no) thiab xaiv cov lus qhia
Muaj ntau ntau hom fiber ntau Media Converters, uas txhawb cov kev cai sib txawv thiab cov nqi sib kis. Lawv tuaj yeem raug cais raws li kev ua haujlwm thiab kev sib kis xov xwm. Raws li kev ua haujlwm, lawv tuaj yeem muab faib ua kev tswj hwm thiab tsis tswj hwm fiber ntau Media Converter, PoE Hloov, Mini MC, qib qib MC, thiab lwm yam.
Tswj thiab tswj tsis tau MC
Unmanaged fiber ntau MC yog ntsaws thiab ua si. Nws yog ib qho yooj yim rau novices rau nruab thiab teeb meem. Nws tso cai rau cov khoom siv hauv lub network tuaj yeem sib txuas lus hauv lub network. Txawm li cas los xij, tsis muaj kev tswj hwm fiber ntau MCs tsis tuaj yeem muab kev tswj hwm fiber ntau optic transceivers. Tib theem ntawm kev saib xyuas kev ua haujlwm, kev kuaj xyuas qhov yuam kev thiab kev teeb tsa ua haujlwm. Yog tias nws tsuas yog ua raws li kev siv yooj yim lossis kev tswj hwm kev xav tau, rau cov tuam txhab me lossis chaw ua si, tsis muaj kev tswj hwm fiber ntau MCs tuaj yeem ua tau raws li koj xav tau. Kev tswj hwm fiber ntau MCs txhawb nqa kev tswj hwm kev tswj hwm hauv chav kawm, thiab tuaj yeem ua tiav kev tswj hwm thiab kev saib xyuas zoo hauv kev tswj hwm kev tswj hwm hauv nruab nrab thiab ntug kev sib txuas. Nws tuaj yeem muab cov haujlwm saib xyuas lub network ntxiv, kev kuaj xyuas qhov tsis raug thiab kev teeb tsa chaw taws teeb, tab sis lawv kim dua. Rau cov cheeb tsam nyuaj xws li cov chaw zov me nyuam loj thiab cov chaw lag luam, thaum muaj kev tswj xyuas zoo dua thiab kev saib xyuas cov tsheb khiav hauv lub network, kev tswj hwm fiber ntau MCs yog thawj qhov kev xaiv rau kev ruaj ntseg thiab kev ntseeg tau ntau dua.
Tsis yog-PoE thiab PoE fiber ntau MCs
PoE (Power over Ethernet) fiber ntau MCs kuj tuaj yeem muab lub zog rau Ethernet li, xws li IP xov tooj, cov cuab yeej sib tham video, lub koob yees duab soj ntsuam, thiab cov khoom siv Wifi, thaum xa cov ntaub ntawv. Yog li ntawd, PoE fiber ntau MCs tuaj yeem siv dav hauv kev sib txuas ntawm cov koob yees duab kev ruaj ntseg thiab cov ntsiab lus nkag wireless hauv qee qhov chaw nkag tsis tau. Cov duab hauv qab no qhia txog cov xwm txheej ntawm kev siv PoE fiber ntau MCs.
Kev lag luam thiab kev lag luam fiber ntau MCs
Qhov kev lag luam-qib kho qhov muag MC tshwj xeeb yog tsim los rau kev lag luam hnyav. Kev khiav hauj lwm kub yog -40 degree rau 85 degree . Nws muaj kev tiv thaiv hluav taws xob thiab hluav taws xob tsis pub tsawg dua 4KV thiab IP40 plua plav pov thawj hluav taws xob, txawm tias nyob hauv thaj chaw txaus ntshai. Piv txwv li, kev tshawb nrhiav roj, nkev roj drilling, mining, thiab lwm yam, kuj tuaj yeem ua kom muaj kev ruaj ntseg ntawm kev sib txuas hauv network. Kev lag luam-qib kho qhov muag fiber ntau mcs yog tsim rau ib puag ncig nrog kev ua haujlwm kub txij li -10 degree mus rau 55 degree, xws li kev lag luam network, tsev kawm ntawv network, thiab cov chaw zov me nyuam.
Txheem thiab mini fiber ntau MCs
Lub nti ntawm lub mini fiber ntau optic MC zoo dua li tus qauv fiber ntau MC, thiab nws qhov zoo dua yog tias nws muaj DIP hloov ua haujlwm uas tuaj yeem ua tau raws li qhov xav tau sib txawv. Vim nws qhov loj me me, mini-hom optical MCs yog qhov nrov heev hauv cov cheeb tsam network loj.
Raws li qhov nruab nrab kis tau tus mob, fiber ntau optic MCs tuaj yeem muab faib ua fiber ntau MCs (optical MCs) siv rau lub network txuas tooj liab cables thiab kho qhov muag cables thiab fiber ntau MCs siv rau lub network txuas optical cables.
Optical fiber MC siv rau tooj liab cable rau optical cable txuas network
Optical MCs tuaj yeem hloov cov teeb liab hluav taws xob rau cov teeb liab kho qhov muag (thiab ua lwm yam) kom txuas ntxiv qhov sib kis. Lawv feem ntau yog siv nyob rau hauv qhov chaw network tiag tiag uas Ethernet cables tsis tuaj yeem them thiab cov fibers kho qhov muag yuav tsum tau siv los txuas ntxiv kev sib kis. Lawv feem ntau yog nyob rau hauv broadband metropolitan cheeb tsam. Hauv daim ntawv thov txheej txheej nkag ntawm lub network. Optical MCs tuaj yeem muab kev sib txuas rau Ethernet, Fast Ethernet, Gigabit thiab 10 Gigabit Ethernet khoom; TDM (Lub Sijhawm Division Multiplexing) kho qhov muag fiber ntau MCs txuas ntxiv qhov kev sib kis ntawm ib txwm siv TDM kev sib txuas lus raws tu qauv tooj liab cables; serial rau kho qhov muag hloov dua siab tshiab Lub optical fiber MCs muaj peev xwm muab kho qhov muag fiber ntau rau serial raws tu qauv tooj liab cable kom nthuav cov kis tau tus mob nyob deb, yog li ntawd lub photoelectric hloov dua siab tshiab transceiver yog heev haum rau point-to-point kev twb kev txuas.
Optical MCs siv nyob rau hauv kev sib txuas network ntawm optical cables
Optical fiber MC siv nyob rau hauv kev sib txuas network ntawm optical cables tuaj yeem paub ib leeg-multimode, ib leeg-dual fiber ntau thiab wavelength hloov dua siab tshiab (tsuas yog hloov cov pa wavelengths rau WDM wavelengths). Thaum qhov chaw nres nkoj ntawm cov cuab yeej qub yog ntau hom, tab sis ib qho khoom siv ib hom yuav tsum tau siv los txuas, ntau hom rau ib hom hloov pauv yog xav tau nyob rau lub sijhawm no. Multimode fiber optic MCs txuas rau hauv cheeb tsam hauv cheeb tsam network los ntawm fiber ntau jumpers, uas tuaj yeem ncav cuag qhov sib kis ntawm 2km, thiab feem ntau yog siv rau hauv kev sib kis luv luv. Ib hom optical fiber ntau transceiver tuaj yeem ncav cuag qhov kev ncua deb ntawm 2km mus rau 100km, uas yog tsim rau kev sib kis ntawm kev lag luam tes hauj lwm lossis kev sib txuas hauv tsev kawm ntawv. Raws li pom hauv daim duab hauv qab no, ib hom thiab ntau hom fiber ntau optic MCs yog siv los txuas ob lub tsev thiab cov chaw zov me nyuam.
Xaus
Fiber optic MCs yog ib qho kev daws teeb meem zoo rau kev sib txuas cov fibers optical thiab tooj liab hauv lub network. Optoelectronic MCs tuaj yeem ua tiav photoelectric hloov dua siab tshiab (hluav taws xob-rau-kho qhov muag hloov dua siab tshiab) kom txuas ntxiv qhov kev sib kis, thaum fiber ntau optic MCs siv hauv kev sib txuas ntawm cov khoom siv kho qhov muag tuaj yeem paub txog ib leeg-multimode, ib leeg-dual fiber ntau thiab wavelength hloov dua siab tshiab. Txij li thaum muaj ntau hom fiber ntau optic MCs, lawv tuaj yeem siv rau ntau qhov chaw. Yog li ntawd, thaum xaiv qhov tsim nyog fiber ntau optic MCs, koj yuav tsum xav txog koj cov kev xav tau hauv network.
