Cov qauv thiab pawg ntawm Cat network cables

Hauv kev sib txuas lus hauv lub network, thaum nws los txog rau Ethernet cables, nws feem ntau hais tias muaj tsib hom kev sib txuas lus network, rau 6 hom network cables, thiab xya hom network cables.Nyob rau hauv xyoo tas los no, Cat8 Class 8 network cables kuj tau hais ntau dua.Qhov tseeb Cat8 Class 8 network cable yog lub cim tshiab ntawm ob lub shielded (SFTP) network jumper, uas muaj ob lub teeb liab khub uas tuaj yeem txhawb nqa bandwidth ntawm 2000MHz thiab kis tau tus nqi mus txog 40Gb / s.Txawm li cas los xij, nws qhov siab tshaj plaws kis tau tus mob tsuas yog 30m, yog li nws feem ntau yog siv rau kev sib txuas cov servers, keyboards, faib thav duab, thiab lwm yam khoom siv hauv cov chaw khaws ntaub ntawv luv luv.Tam sim no, muaj tsib hom network cables nyob rau hauv kev ua lag luam: super tsib network cables, rau network cables, super six network cables, xya network cables, thiab super xya network cables.Cat8 Qeb 8 network cables, zoo li Qeb 7 / Ultra Qeb 7 network cables, yog ob qho tib si shielded twisted khub cables thiab tuaj yeem siv rau hauv cov chaw zov me nyuam, kev kub ceev, thiab bandwidth intensive cheeb tsam.Txawm hais tias qhov kev ncua deb ntawm Cat8 Qeb 8 network cables tsis deb npaum li ntawm Qeb 7 / Ultra Qeb 7 network cables, lawv qhov ceev thiab zaus ntau dua li ntawm Qeb 7 / Ultra Qeb 7 network cables.Muaj qhov sib txawv tseem ceeb ntawm Cat8 Qeb 8 network cables thiab Super Qeb 5 network cables, nrog rau Qib 6 / Super Qeb 6 network cables, feem ntau cuam tshuam txog kev ceev, zaus, kis nrug deb, thiab kev siv

Qeb 1 cable (CAT1): Qhov siab tshaj plaws bandwidth ntawm lub cable yog 750kHz, siv rau lub tswb nrov, los yog tsuas yog rau lub suab kis tau tus mob (Qeb 1 cov qauv yog tsuas yog siv rau cov xov tooj cables ua ntej 1980s), txawv ntawm cov ntaub ntawv kis tau tus mob.

CAT2: Qhov siab tshaj plaws bandwidth ntawm lub cable yog 1MHZ, uas yog 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 4Mbps.Nws yog feem ntau siv hauv cov qub token tes hauj lwm uas siv 4MBPS Token dhau raws tu qauv.

CAT3: yog hais txog cable teev nyob rau hauv ANSI thiab EIA/TIA568 tus qauv tam sim no.Qhov sib kis zaus ntawm cov cable no yog 16MHz, thiab qhov siab tshaj plaws kis tau tus mob yog 10Mbps (10Mbit / s).Nws yog tsuas yog siv hauv lub suab, 10Mbit / s Ethernet (10BASE-T) thiab 4Mbit / s Token Ring.Qhov siab tshaj plaws network ntu ntev yog 100m.RJ hom connectors yog siv, uas tau ploj mus ntawm lub khw.

Qeb 1 cable (CAT1): Qhov siab tshaj plaws bandwidth ntawm lub cable yog 750kHz, siv rau lub tswb nrov, los yog tsuas yog rau lub suab kis tau tus mob (Qeb 1 cov qauv yog tsuas yog siv rau cov xov tooj cables ua ntej 1980s), txawv ntawm cov ntaub ntawv kis tau tus mob.

CAT2: Qhov siab tshaj plaws bandwidth ntawm lub cable yog 1MHZ, uas yog 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 4Mbps.Nws yog feem ntau siv hauv cov qub token tes hauj lwm uas siv 4MBPS Token dhau raws tu qauv.

CAT3: yog hais txog cable teev nyob rau hauv ANSI thiab EIA/TIA568 tus qauv tam sim no.Qhov sib kis zaus ntawm cov cable no yog 16MHz, thiab qhov siab tshaj plaws kis tau tus mob yog 10Mbps (10Mbit / s).Nws yog tsuas yog siv hauv lub suab, 10Mbit / s Ethernet (10BASE-T) thiab 4Mbit / s Token Ring.Qhov siab tshaj plaws network ntu ntev yog 100m.RJ hom connectors yog siv, uas tau ploj mus ntawm lub khw.Qeb 4 cable (CAT4): qhov zaus kis tau tus mob ntawm hom kab no yog 20MHz, uas yog 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 16Mbps (xa mus rau 16Mbit / s Token Ring).Nws yog tsuas yog siv rau token raws LAN thiab 10BASE-T / 100BASE-T.Qhov siab tshaj plaws network ntu ntev yog 100m.RJ hom connectors yog siv, uas tsis yog siv dav

CAT5: Hom kab no tau ua kom muaj zog ntawm cov kab hluav taws xob ntau dua thiab yog coated nrog cov khoom zoo insulating.Qhov siab tshaj plaws bandwidth ntawm lub cable yog 100MHz, thiab qhov siab tshaj plaws kis tau tus mob yog 100Mbps.Nws yog 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.Nws yog tsuas yog siv rau 100BASE-T, thiab qhov siab tshaj plaws network ntu ntev yog 100m.RJ hom connectors yog siv.Qhov no yog feem ntau siv Ethernet cable nyob rau hauv ib tug twisted khub cable, nrog sib txawv khub muaj sib txawv pitch lengths.Feem ntau, lub sij hawm twisting ntawm plaub khub ntawm twisted khub yog nyob rau hauv 38.1 hli, twisted counterclockwise, thiab twisting ntev ntawm ib khub yog nyob rau hauv 12.7 hli.

CAT5e: CAT5e muaj tsawg attenuation, tsis tshua muaj crosstalk, siab dua attenuation rau crosstalk piv (ACR), cov qauv rov qab poob, thiab me me yuam kev, txhim kho kev ua tau zoo.Super Class 5 cables yog siv rau gigabit Ethernet (1000Mbps)
