    Kev tshuaj xyuas cov teeb meem tshwm sim hauv kev kuaj fiber ntau

    Post lub sij hawm: Apr-01-2020

    Cov ntu hauv qab no muab cov ncauj lus kom ntxaws txog cov teeb meem tshwm sim hauv kev kuaj fiber ntau.

    (1) Vim li cas qhov kev xeem fiber ntau dhau tab sis cov pob ntawv tseem poob thaum lub sijhawm ua haujlwm hauv lub network?

    Hauv kev xaiv ntawm tus qauv, ntau tus neeg siv yuav ua qee qhov yuam kev, xws li them nyiaj me ntsis rau seb qhov ntsuas fiber ntau yog 50μm lossis 62.5μm.

    Cov kev xav tau rau qhov poob siab tshaj plaws ntawm ob-aperture fibers yog qhov loj. Kev xaiv tsis raug ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas yuav ncaj qha mus rau qhov hloov ntawm qhov kev txiav txim siab pib. Piv txwv li, yog tias qhov ntsuas qhov sib txuas tiag tiag yog 50μm fiber ntau, thiab cov qauv kev sim xaiv yog 62.5μm, thiab daim ntawv thov yog 100Base-FX, piv txwv li qhov ntsuas tau yog 10dB, tus neeg ntsuas yuav tau txais qhov txiaj ntsig PASS, thiab qhov xwm txheej tiag tiag yuav tsum yog. tsis tsim nyog Vim tias nws dhau qhov kev txiav txim siab ntawm 6.3dB.

    Qhov no teb cov lus nug dhau los, thiab kev xeem dhau, tab sis vim li cas cov ntaub ntawv tseem yuav poob pob ntawv.

    (2) Vim li cas 10 Gigabit tus nqi tseem tsis tau txais kev txhawb nqa thaum nws dhau 10 Gigabit tus qauv?

    Muaj cov neeg siv zoo li no uas txhim kho lub nraub qaum ntawm lub network. Lawv yuav hloov kho cov modules ntawm lubhloovthiab lub server. Tau kawg, lawv tseem yuav sim qhov poob ntawm fiber ntau hauv lub network. Nws zoo nkaus li tias tsis muaj teeb meem hauv txoj kev. Cov fiber ntau tau raug kuaj kom ua tau raws li qhov yuav tsum tau muaj ntawm 10 Gigabit network. , Qhov poob yog tsawg dua li tus qauv txwv, tab sis qhov kev ua haujlwm tiag tiag tseem tsis zoo tagnrho.

    Yog vim li cas rau kev tsom xam yog feem ntau yog tias hom bandwidth ntawm fiber optic cable tsis suav nrog. Hom bandwidth ntawm fiber ntau optic cables sib txawv nruab nrab yog qhov siab tshaj plaws bandwidth uas tuaj yeem muab tau nyob rau hauv ib qho kev ncua deb. Qhov loj ntawm hom bandwidth, qhov ntau dua qhov sib kis tus nqi nyob rau hauv ib qho kev ncua deb.Lawv tau xa mus rau xyoo dhau los. Feem ntau, hom bandwidth kuj qis, tsawg dua 160. Vim li ntawd, qhov ceev tsis tuaj yeem nce ntxiv vim qhov kev ncua deb ntev dua, txawm hais tias qhov poob yog qhov siv tau rau lub sijhawm no.

    (3) Qhov kev xeem poob yog raws li tus qauv, thiab tsis muaj teeb meem nrog hom bandwidth. Vim li cas thiaj muaj teeb meem hauv kev ua haujlwm tiag tiag?

    Peb tseem muaj kev nkag siab yuam kev hauv qhov kev xeem. Ntev npaum li qhov poob dhau, cov fiber ntau suav tias yog qhov ua tau zoo, tab sis qhov no tsis yog qhov teeb meem. Piv txwv tias qhov xwm txheej zoo li no, tus qauv tsim yuav tsum muaj qhov kev sib txuas tsis yog 2.6dB. Qhov poob ntawm lub taub hau adapter yog ntau tshaj 0.75dB, tab sis tag nrho qhov txuas poob tseem tsawg dua 2.6dB. Lub sijhawm no, yog tias koj tsuas sim qhov poob, koj yuav tsis pom qhov teeb meem adapter, tab sis hauv kev siv network tiag tiag, nws yuav yog vim qhov teeb meem adapter. Raws li qhov tshwm sim, qhov kev sib kis me ntsis yuam kev tus nqi tau nce ntau heev.
