Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, network cable thiab optical fiber tau dhau los ua ob qhov tseem ceeb tshaj plaws hauv kev sib txuas lus network.Nyob rau hauv cov teeb liab kis tau tus mob, optical fiber muaj ntau yam zoo, xws li ntev kis tau tus mob nyob deb, ruaj khov teeb liab, me me attenuation, kev kub ceev, thiab lwm yam., uas ua tau raws li tej kev xav tau ntawm lub network.Nws tua tag nrho lub network cable txhua feeb, yog li qhov txawv ntawm optical fiber thaj qaum thiab network cable yog dab tsi?
Txawv txhais
Patch cord yog qhov tseeb ntawm cov hlau txuas hlau txuas ob lub ntsiab lus ntawm lub rooj tsav xwm Circuit Court (PCB).Vim yog cov khoom tsim sib txawv, cov hlua khi siv cov khoom sib txawv thiab cov thicknesses.
Network cable yog qhov tseem ceeb los txuas LAN.Cov kab hluav taws xob sib txuas hauv cheeb tsam hauv cheeb tsam feem ntau suav nrog cov khub twisted, coaxial cable thiab optical cable.Twisted khub yog cov ntaub ntawv kis tau tus mob muaj li ntawm ntau khub ntawm cov xov hlau.Nws tus yam ntxwv yog tias nws yog pheej yig, yog li nws yog dav siv, xws li peb cov kab xov tooj.Nws yog siv los txuas nrog RJ45 modular plug.
Cov teebmeem sib txawv
Patch cord feem ntau yog siv rau kev sib kis hluav taws xob ntawm tib lub peev xwm thiab rau luv luv thiab txuas ob lub xov hlau.Rau cov neeg uas muaj qhov yuav tsum tau muaj qhov tseeb voltage, qhov hluav taws xob poob tsim los ntawm me ntsis hlau patch qaum kuj yuav muaj kev cuam tshuam zoo rau cov khoom lag luam.Lub network cable yog siv rau kev xa cov ntaub ntawv thiab kev sib txuas rau hauv cheeb tsam hauv cheeb tsam network thiab xa cov ntaub ntawv hauv lub network.
Cov khoom siv sib txawv siv
Cov khoom siv rau lub patch cord yog tooj liab cable, uas yog ua los ntawm cov qauv thaj qaum thiab cov khoom siv sib txuas.Lub patch qaum muaj tooj liab cores txij li ob mus rau yim cores, thiab cov khoom siv sib txuas yog ob 6-ntsis lossis 8-ntsis module plugs, lossis Lawv muaj ib lossis ntau dua liab qab lub taub hau.Qee qhov patch cord muaj ib qho module plug ntawm ib qho kawg thiab ib qho 8-ntsis module qhov ntawm qhov kawg, los yog nruab nrog 100P txuas txuas, MICs, los yog module slots.
Muaj feem ntau twisted khub cable, coaxial cable thiab optical cable.Twisted khub yog cov ntaub ntawv kis tau tus mob muaj li ntawm ntau khub ntawm cov xov hlau.Nws tus yam ntxwv yog tias nws yog pheej yig, yog li nws yog dav siv, xws li peb cov kab xov tooj.Nws yog siv los txuas nrog RJ45 siv lead ua taub hau.Nws muaj STP thiab UTP.UTP feem ntau yog siv.
