Smooth Migration rau 40 / 100GbE nrog OM3 thiab OM4
Qhov yuav tsum tau txuas ntxiv rau kev nthuav dav thiab kev sojntsuam hauv qhov chaw nruab nrab cov kev khiav haujlwm mus rau 40 / 100GbE. Nyob rau hauv tus txheej txheem ntawm kev kho dua rau qhov chaw txuas ntaub ntawv, qhov kev xa tawm cable tseem yog ib qho tseem ceeb. Cov fiber ntau fiber ntau siv nyob rau hauv cov chaw muab kev pabcuam yuav tsum muaj kev ntseeg tau zoo tsis yog rau tam sim no tiam sis tseem siv tau rau yav tom ntej. OM3 thiab OM4 yog muaj raws li cov kabmob yav tom ntej rau 40/100 Gigabit Ethernet network. Niaj hnub no, peb tab tom yuav los ua kom paub ob hom kab xov tooj no.
Raws li peb paub, multimode fiber ntau categorized ua plaub yam - OM1, OM2, OM3 thiab OM4. OM3 thiab OM4 yog laser-optimized, high-bandwidth 50 micron multimode fiber cables, uas yog tsim los txhim kho cov kev pabcuam them nqi ntawm 850nm ntsug kabmob nto emitting lasers (VCSELs) rau cov kev siv 1G thiab 10G tam sim no thiab yav tom ntej 40G thiab 100G daim ntaub ntawv. Cov duab hauv qab no qhia tau hais tias OM3 thiab OM4.
Raws li kev tsim kom tau cov kev hloov bandwidth yog hu ua cov tshiab, tshwj xeeb tshaj yog 40 thiab 100GbE cov qauv, kev kis dua fiber ntau optic cables uas muaj nyob hauv cov tsev kho mob tam sim no yuav ua rau muaj kev txwv ntau dua. Thiab cov kev xav tau ntau dua qhov no yuav tsum tau muaj kev xav tau los ntawm kev siv nyiaj ntau-qhov multimode systems kom kim tib hom tshuab. Kom txog thaum OM3 thiab OM4 tau teev tseg, ntau cov cim ntxiv ntawm 40 / 100GbE yuav tsum tau ua rau cov leap mus rau ib hom kev daws teeb meem. OM3 thiab OM4 muaj ntau yam zoo uas pab txhawm rau txoj kev tsiv mus rau 40 / 100GbE.
High Bandwidth: Bandwidth yog thawj qhov laj thawj vim li cas OM3 thiab OM4 nyiam. OM3 thiab OM4 yog qhov zoo tshaj plaws rau kev xa xov 850nm thiab muaj tsawg kawg yog 2000 MHz • thiab 4700 MHz • qhov zoo ntawm qhov hloov modal bandwidth (EMB), thaum OM1 thiab OM2 nrog qhov siab tshaj 500 MHz • km raws li peb tuaj yeem pom hauv qab rooj. Nws yog pom tseeb tias nrog OM3 thiab OM4, qhov chaw kho qhov muag kho tau zoo hauv qhov chaw nruab nrab yuav ua tau raws li cov qauv kev tsim los ntawm IEEE rau kev siv bandwidth.
Kev Ntev Mus Ntev Ntev: Qhov kis tau tus kabmob ntawm cov kabmob fiber ntau yuav cuam tshuam cov chaw nruab nrab ntawm cov ntaub ntawv. Muab piv rau cov khoom siv fiber ntau multimode, OM3 thiab OM4 tuaj yeem txhawb zog dua kis dua. Feem ntau, OM3 muaj peev xwm khiav ntawm 40/100Gbps ntawm 100 meters thiab OM4 tuaj yeem txhawb qhov txuas ntev txog 150 meters ntawm cov ntaub ntawv txog 40/100Gbps.
Tsawg Insertion poob: Insertion poob txhua lub sij hawm yog qhov tseem ceeb tshaj uas yuav tsum xav txog thaum lub sij hawm ntawm cov ntaub ntawv chaw cabling. Qhov qis dua qhov yuam kev, qhov ua tau zoo dua. Raws li tus txheej txheem 40 / 100G, OM3 teev rau 100m nrug nrog lub siab tshaj plaws channel poob ntawm 1.9dB, thiab OM4 teev rau ib tug 150m nrug nrog lub siab tshaj plaws channel poob ntawm 1.5 dB, nrog rau tag nrho connector poob peev ntawm 1.0 dB raws li peb tuaj yeem pom ntawm cov lus hauv qab no.
Kev Them Nqi Qis: Kev siv nyiaj yog ib qho tseem ceeb tshaj plaws uas yuav tsum tau muab coj los xav thaum teem tau cov chaw khaws ntaub ntawv. Raws li peb tau hais los saum toj no, thaum kho kom yooj yim dua bandwidth network yav dhau los, muaj ntau tus IT tswj yuav xaiv tus nqi qis ib hom fiber kom mus cuag cov kev sib txuas, tab sis nrog rau cov tsos ntawm OM4, tus nqi siv hauv kev tsiv mus rau 40 / 100GbE yuav zoo heev.
Ua tau, OM3 muaj cov kev kawm zoo li OM4 los ntawm plaub yam uas peb tau tham saum toj no, tab sis nrog OM3, vim li cas peb tseem xav tau OM4?
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias OM4 tsis tas yuav tsim los hloov OM3. Rau feem ntau cov tshuab, OM3 yog txaus los npog qhov kev xav tau ntawm cov kev siv bandwidth ntawm txoj kev ntawm qhov chaw pib teeb tsa tam sim no. Feem ntau cov kev cai ntawm tus qauv tseem muaj peev xwm ua tau zoo thiab muaj txiaj ntsig zoo nrog OM3. Thawj cov nyiaj pab uas OM4 qhia tau ntxiv rau ntawm kev sib koom ua ke txuas ntxiv ntawm tus nqi tag nrho tseem tsawg tshaj li qhov ntawm OS2 ib hom kab ke. Muab txhais tau tias, OM4 muab kev kho uas tso cai rau ntau qhov kev sib txuas kom tsis txhob muaj cov nqi qis dua ib hom tshuab. Txuas ntxiv, OM4 muab lub sijhawm rau cov kabmob txuas rau yav tom ntej. OM4 rov qab tag nrho-tshaj cov kab mob OM3 uas twb muaj lawm. Qhov ntxiv bandwidth thiab txo attenuation ntawm OM4 muab ntxiv insertion poob npoo. Yog li ntawd, cov neeg siv ntawm OM4 tau txais nyiaj ntxiv kom muaj kev nyab xeeb los pab tiv thaiv kom tsis txhob muaj qhov zoo tshaj qhov cabling installations thiab muab cov npoo rau kev degradation vim kev txav, ntxiv, thiab hloov ntawm lub neej ntawm kev teeb tsa.
Raws li puas tau-xav tau ntxiv rau kev sib txuas lus dua, kev kho kom zoo dua rau 40 / 100GbE no. OM3 thiab OM4, raws li yav tom ntej-pov thawj cab, ua si ib qho tseem ceeb hauv txoj kev tsiv teb tsaws mus rau cov kev sib txuas ua ke dua bandwidth. FOCC muab ntau ntawm OM3 thiab OM4 nyob hauv ntau hom raws li koj xav tau, thiab peb tau npaj kom muaj feem ntau cov nqi fiber ntau optic cable nqi rau cov neeg muas zaub.
