Txhawm rau nkag siab cov kab hluav taws xob network thaiv, koj xub yuav tsum nkag siab qhov sib txawv ntawm cov network txuas uas tsis muaj kev tiv thaiv thiab cov thaiv kab thaiv network. Cov ntaub thaiv npog sib txuas ua ke yog ib txoj hlua uas muaj kev tiv thaiv kev tiv thaiv thiab tuaj yeem tshem tawm qhov kev ntxias tam sim no rau hauv av. Unshielded twisted pair cables tsis muaj cov haujlwm no. Txawm li cas los xij, vim nws lub luag haujlwm muaj zog, txheej txheem teeb tsa ntawm cov thaiv kab hlau txuas network yuav raug nqi tiv thaiv ntxiv. Yog li ntawd, cov ntaub thaiv kab thaiv sib txuas ua ke tau them nqi me ntsis ntau dua li cov khoom sib txuas uas tsis muaj kev tiv thaiv, thiab kev saib xyuas ntau dua yog them rau kev tiv thaiv. Yog tias cov neeg siv muaj qhov xav tau siab dua rau kev ua haujlwm, feem ntau Nws yog qhov zoo dua los siv cov ntaub thaiv npog sib tw.
Kev tiv thaiv kab mob sib txuas network feem ntau tau muab faib ua ob txheej txheej tiv thaiv, uas yog braided tiv thaiv thiab tiv thaiv zaj duab xis.
Cov ntaub thaiv npog yog braided los ntawm cov tooj liab liab liab lossis tinned tooj liab xaim rau hauv txheej txheej txheej thaiv, uas muaj kev coj ua tau zoo dua thiab txo suab nrov dua li txhuas. Nws tuaj yeem yooj yim dua txuas rau qhov txuas los ntawm crimping thiab vuam cov braid. Cov. Txawm li cas los xij, qhov tsis zoo ntawm braided shielding yog tias 100% kev pabcuam tsis tuaj yeem ua tiav. Hauv kev xav, txoj hlua khi yog 70% txog 95% kev pab them nqi. Hauv cov ntawv thov tiag tiag, 70% kev pab them nqi tom qab txuas kab yog txaus.
Lwm hom kev tiv thaiv zaj duab xis yog siv cov txheej txheej txhuas txhawm rau tiv thaiv, uas tuaj yeem ua tiav 100% kev tiv thaiv ib puag ncig tus neeg xyuas pib, tab sis qhov tsis zoo yog qhov nws ua tau qis dua li ntawm tooj liab braided shielding.
(U=unshielded; F=film shield; S=woven shield; TP=twisted pair) Cov qauv tiv thaiv zoo:
Ib leeg-txheej tiv thaiv: UTP thiab FTP yog ib leeg-shielded network cables uas feem ntau siv txhuas ntawv ci. Cov qauv no muaj cov ntaub thaiv npog rau txhua khub lossis plaub khub sib tw ua ke saum tus neeg xyuas pib thiab cov rwb thaiv tsev, thiab cov ntaub thaiv npog cais tuaj yeem tiv thaiv cov khub uas nyob ib sab ntawm tus ntoo khaub lig.
Kev tiv thaiv tag nrho: F/UTP, S/UTP thiab SF/UTP tau tiv thaiv tag nrho los ntawm cov ntaub ntawv tiv thaiv sib txawv." Integral" hais txog lub cev xaim npog, uas pab tiv thaiv EMI (cuam tshuam hluav taws xob) los ntawm kev nkag los lossis tawm ntawm txoj hlua.
Kev tiv thaiv ob zaug: F/FTP, S/FTP thiab SF/FTP yog ib tus zuj zus thiab tiv thaiv ib leeg, nrog ob txheej txheej tiv thaiv, uas zoo heev txhim kho lub peev xwm los tiv thaiv kev cuam tshuam hluav taws xob.
