Dab tsi yog qhov txawv ntawm Ca5e, Cat6, thiab Cat7?

Qeb Tsib (CAT5): Cov zaus kis tau tus mob yog 100MHz, siv rau lub suab kis tau tus mob thiab cov ntaub ntawv kis tau tus mob nrog lub siab tshaj plaws kis tau tus mob ntawm 100Mbps, feem ntau yog siv nyob rau hauv 100BASE-T thiab 10BASE-T tes hauj lwm.Qhov no yog qhov feem ntau siv Ethernet cable.Hom kab no ua rau muaj kev sib tw winding ceev thiab coats cov khoom zoo insulating.Tam sim no lub Qeb 5 cable yeej tsis siv ntau.

Qeb 5e (CAT5e): Qhov sib kis zaus yog 100MHz, feem ntau yog siv rau Gigabit Ethernet (1000Mbps).Nws muaj me me attenuation, tsawg crosstalk, siab dua attenuation thiab crosstalk piv (ACR) thiab teeb liab-rau-suab nrov piv (Structural Rov Loss), thiab me me qeeb yuam kev, thiab kev ua tau zoo heev.Hauv cov haujlwm tiag tiag, txawm hais tias Qeb 5 cables kuj tuaj yeem xa tawm gigabit, nws tsuas yog pom zoo rau kev sib kis luv luv gigabit.Kev xa mus ntev gigabit yuav tsis ruaj khov.Qhov no kuj yog ib qho txhaum ntau hauv qhov project, thiab nws yooj yim tsis quav ntsej.Qhov teeb meem.

Qeb Rau (CAT6): Cov zaus kis tau tus mob yog 250MHz, uas yog qhov tsim nyog tshaj plaws rau cov ntawv thov nrog cov nqi sib kis siab dua 1Gbps, feem ntau yog rau Gigabit Ethernet (1000Mbps).Qeb 6 twisted khub yog txawv ntawm Qeb 5 los yog Qeb 5 super twisted khub nyob rau hauv tsos thiab qauv, tsis tsuas yog ib tug insulating ntoo khaub lig ncej ntxiv, tab sis plaub khub ntawm twisted khub yog muab tso rau ntawm plaub sab ntawm tus ntoo khaub lig ncej raws li.nyob rau hauv ib tug zawj, thiab txoj kab uas hla ntawm lub cable kuj thicker.

Super rau los yog 6A (CAT6A): qhov zaus kis tau tus mob yog 200 ~ 250 MHz, qhov siab tshaj plaws kev sib kis ceev kuj tuaj yeem ncav cuag 1000 Mbps, feem ntau yog siv hauv gigabit networks.Qeb 6e cable yog ib qho kev txhim kho ntawm Qeb 6 cable.Nws tseem yog ib qho tsis muaj kev tiv thaiv kab sib tw uas tau teev tseg hauv ANSI / EIA / TIA-568B.2 thiab ISO Qeb 6 / Class E cov qauv.Piv nrog rau lwm yam, muaj kev txhim kho loj.

Qib Xya (CAT7): Cov zaus kis tau tus mob tuaj yeem ncav cuag tsawg kawg 500 MHz thiab tus nqi sib kis tuaj yeem ncav cuag 10 Gbps.Nws yog tsuas yog hloov mus rau daim ntawv thov thiab kev loj hlob ntawm 10 Gigabit Ethernet technology.Cov kab no yog qhov tseeb shielded twisted khub hauv ISO Qeb 7.

Lub ntsiab sib txawv ntawm ntau hom hlau

Qhov sib txawv 1: Qhov sib txawv ntawm kev poob, qhov sib txawv tseem ceeb ntawm Qeb 6 cable thiab Qeb 5e network cable yog qhov kev ua tau zoo dua qub nyob rau hauv cov nqe lus ntawm crosstalk thiab rov poob.Nws raug pom zoo kom siv Qeb 6 network cables ncaj qha rau kev kho kom zoo nkauj hauv tsev.

Qhov txawv 2. Lub thickness ntawm cov tub ntxhais hlau yog txawv.Cov tub ntxhais hlau ntawm super tsib hom network cable yog nruab nrab ntawm 0.45mm thiab 0.51mm, thiab cov tub ntxhais hlau ntawm rau hom network cable yog nruab nrab ntawm 0.56mm thiab 0.58mm.Lub network cable yog tuab dua;

Qhov sib txawv 3: Cov qauv cable sib txawv.Sab nrauv ntawm super tsib-hom network cable muaj "CAT.5e" logo, thiab rau-hom network cable muaj qhov pom tseeb tshaj plaws "cross thav duab", thiab daim tawv nqaij muaj "CAT.6" logo.
