Patch cords, uas yog ib qho tseem ceeb ntawm cov kab hluav taws xob, tau raug kev txom nyem ntev los ntawm kev tsis saib xyuas. Kev ntsuam xyuas ntawm cov hlua khi tau tsuas yog hais hauv cov qauv hauv ob xyoos dhau los. Ntau cov qauv luam tawm tom qab, suav nrog:
①TIA/EIA-568-A-4-1999: Kev xa tawm qeeb thiab ncua sij hawm sib txawv Specification rau 100-Ohm 4-pair Cables
②TIA/EIA-568-A-5-2000: 100-Ohm 4-Pair Enhanced Qeb 5 Cabling Specification
③TIA/EIA-568-B Part 2: 100Ω Balanced Twisted Pair Component Standard, npog thaj qaum kuaj txoj kev thiab cov cai rau Ca.5 thiab Cat.5e. TIA/EIA-568B.2-1 Qeb 6 cabling tus qauv muab cov kev cai tshwj xeeb rau cov hlua khi.
Thawj cov chaw tsim khoom thaj cords yog tsim los nrog cov txheej txheem nruj, siv ntau -strand saj zawg zog hlau tsim, thiab tuaj yeem tiv taus ntau qhov rov qab ntxig thiab tshem tawm.
