Electromagnetic cuam tshuam (EMI) feem ntau muaj nyob rau hauv ib puag ncig kev lag luam vim muaj lub cev muaj zog, cov khoom siv vuam, lub zog hloov hluav taws xob, thiab cov tsav tsheb sib txawv. Shielded Ethernet cables xws li S/FTP, SF/UTP, los yog U/FTP pab txo cov crosstalk thiab EMI cuam tshuam, ua kom cov ntaub ntawv muaj kev ncaj ncees thoob plaws kev xa tawm. Txawm hais tias qhov kev xaiv tsis muaj kev tiv thaiv yuav muaj txaus nyob rau hauv kev cuam tshuam tsawg, nws raug nquahu kom siv cov ntaub thaiv npog M12 hauv feem ntau cov xwm txheej.
Tsuas yog kev tiv thaiv, cov khoom siv cable jacet kuj tseem ceeb rau kev ua haujlwm ntawm M12 ethernet cable.
Thaum xaiv M12 Ethernet cables, ua tib zoo tshuaj xyuas ntau yam tshwj xeeb. Rau qeb thiab bandwidth, Cat5e txhawb 100 Mbps rau 1 Gbps, haum rau cov ntawv thov yooj yim. Cat6 muab 1Gbps, thiab qee zaum, 10Gbps rau kev ncua deb ntawm 50 meters lossis tsawg dua. Cat6a muab kev sib kis ceev ntawm 10 Gbps hauv thaj tsam ntawm 100 meters, ua qhov kev xaiv zoo tshaj plaws rau yav tom ntej.
Cov ntaub ntawv sheath yog lwm qhov tseem ceeb. PUR (polyurethane) muaj qhov hloov tau yooj yim, hnav tsis kam, roj tsis kam, thiab tshuaj lom neeg ua haujlwm. PVC (polyvinyl chloride) yog kev lag luam ntau dua thiab tsim nyog rau kev teeb tsa nrog lub cev qis dua. LSZH (cov pa luam yeeb tsawg, halogen-dawb) raug pom zoo siv rau hauv qhov chaw tseem ceeb ntawm hluav taws uas yuav tsum muaj cov pa phem tsawg. Qhov kub thiab txias kuj tseem ceeb heev, thiab qhov ntsuas kub ntawm lub cable feem ntau yog -40℃C rau +85℃C lossis siab dua, nyob ntawm daim ntawv thov. Xws li cov xaim xaim thiab braided shielding pab nrog grounding thiab ntxiv stabilizes teeb liab kev ncaj ncees nyob rau hauv hluav taws xob kev nyuaj siab. Thaum kawg, xyuas kom meej tias cov khoom siv cable thiab cov khoom sib txuas muaj tsawg kawg yog IP67 ntsuas los tiv thaiv dej nkag thiab ib puag ncig hnav.
