Hom Txiag Thaj Tsum siv hauv Gigabit Ethernet Applications
Fiber optic thaj qaum yog siv los txuas cov khoom sib txawv hauv lub network, feem ntau hloov cov kev sib txuas, qhov uas yuav tsum muaj kev sib txuas lus ceev nrooj. Tej zaum nws yuav raug kaw vim muaj ob peb sib txuas nrog cov khoom siv.
Fiber thaj cords yog qee zaum hu ua fiber ntau qis thiab yog li ntawd yeej ntev ntawm fiber ntau optic cable tag nrog ib tus neeg siv khoom tsim nyog rau qhov kev tsim nyog installation. Raws li tau piav yav tas los, cov cab plab siv fiber ntau feem ntau nrog ST, SC, LC lossis MTRJ connectors. Muaj ntau ntau hom roj ntau thaj rau ntau yam siv. Cov tshooj no yog hais txog Hom Cua Txij Nkawm .
Hom Dej Txuas Ntsuas Cords, kuj raug xa mus rau hauv cov chaw siv fais fab, yog siv hauv Gigabit Ethernet 1000Base-LX / LH cov kev siv uas lub hom phiaj tabtom xa cov neeg ua haujlwm high-speed 1000Base-LX routers, keyboards, lossis optical transceivers nyob rau hauv ntau hom kab tho txawv . Kev ntsuas lub nplaub tshev siv lub npog 1300nm lossis 1310nm optical wavelength qhov rai, thiab tsis tuaj yeem siv rau 850nm luv luv wavelength qhov rais xws li 1000Base-SX. Tsis tas li ntawd, txhua txoj kev sim txuas mus txuas rau 1000Base-LX / LH cov khoom siv tsawg dua ntawm cov tshuab fiber ntau uas tsis siv cov hom kev siv lub tshuab fiber ntau tuaj yeem ua rau qis dua qhov yuam kev, thiab qhov kawg ua rau lub tsev. Modem lub zog qaum yog ua rau Gigabit Ethernet ntau hom kev siv ntawm 1300nm wavelength; tus qauv thov yog IEEE 802.3z. Txhua hom kev siv lub tshuab fiber ntau optic thaj muaj ua nrog duplex cable; nrog ib hom dav mus rau hom kev lag luam uas muaj fiber ntau txuas rau hauv ib qho ntawm ob ceg.
Hom Cua Txij Nkawm
Vim li cas peb thiaj li yuav tsum tau siv hom kev ntsuas cua txias ? Gigabit Ethernet daim ntawv thov yuav tsum siv cov fiber ntau optic kom muab cov ntaub ntawv qhia txog kev xa mus. Feem ntau cov neeg siv cov lus qhia yoojyim ntev yoojyim rau Gigabit Ethernet. Cov tswv yim no yuav tsum khiav lag luam ob qho tib si thiab ntau hom fibers. Thiab raws li peb txhua tus paub, ntau ntau hom fiber ntau cov tswv yim tsim qhov Performance index ntawm refraction anomalies raws lub centerline ntawm hom ntau hom fiber ntau. Thaum twg ib qho mas ib qho fiber ntau optic teeb raug xa mus rau hauv nruab nrab ntawm ntau hom fiberglass, hom uas propagate los ntawm qhov Performance index ntawm refraction anomalies disseminate lub sij hawm ua modal dispersion. Cov nyhuv no hu ua hom txawv qeeb. Txawv txawv hom qeeb los ntawm kev txo qis qis dua nyob deb li cas. Tso cai rau cov hom laser nkaus xwb los ua qhov chaw ntawm lub nruab nrab ntawm hom fiber ntau, qhov ntsuas qhov ntsuas thaj qaum qeeb rau cov nyhuv ntawm hom sib txawv qeeb.
Los ntawm cov lus piav qhia saum toj no peb kawm paub siv cov cab cab txias hom. Thaum peb siv hom kev ua kom muaj fiber ntau fiber ntau, peb yuav tsum sib txuas cov xim daj ntawm cov xim ntawm ib qho kev sib txuas ntawm cov khoom siv sib txuas (ib hom Gigabit transceiver) thaum peb txuas cov txiv kab ntxwv ceg xim ntawm multimode rau tus tau txais sab (multimode Gigabit cable cog).
Kev tswj cov cua cab hom yog feem ntau siv cov khub. Qhov no txhais tau hais tias koj yuav tsum muaj hom kab ntsuas txias rau txhua qhov kawg mus txuas rau lub iav ntawm lub tshuab cog. Yog li ces cov cables no feem ntau yuam kom nyob rau hauv cov xov tooj. Qhov laj thawj yog vim li cas ib tug neeg yuav txiav txim siab ib kab ntawv yog li ntawd lawv yuav khaws tau nws tseg. Yog hais tias koj qhov kev hloov hauv LX gigabit los nrog SC lossis LC connectors, nco ntsoov xa cov ceg daj (singlemode) los ntawm cov hlua rau sab kis, thiab kuj txiv kab ntxwv txiv kab ntxwv (multimode) ntawm qhov tau txais sab ntawm cov khoom. Nws yog qhov tseem ceeb ntawm txoj kev kho no yuav tswj tuav ob hnub. Qhov sib pauv ntawm kev sib kis thiab tau txais kev ua haujlwm tsuas yog ua haujlwm hauv lub chaw cog phom. Hom tshuaj fiber ntau optic thaj qeeb yog siv thaum koj xav khiav Gigabit Ethernet (LX) ntau hom kev xaiv fiber ntau optic.
Hauv FOCC , qhov ntsuas cua txias yog raws li IEEE 802.3Z txuj. FOCC khoom siv hom kev kho cua txias taub hau nrog SC, ST, LC, MTRJ fiber ntau optic connectors.
