Cat5/5e, Cat6/6a, Cat7 thiab Cat8 Cable: Phau Ntawv Qhia Zoo Tshaj Plaws

2025-02-26

Kuv xav tau ib daim ntawv qhia txog Cat5/5e, Cat6/6a, Cat7, thiab Cat8 cables. Kuv paub txog cov pawg no li cas. Txhua tus lej Cat sawv cev rau cov lus qhia sib txawv rau Ethernet cables, Lawv txawv ntawm qhov ceev, bandwidth, shielding, thiab tej zaum qhov deb uas lawv tuaj yeem xa cov ntaub ntawv tau zoo.

Ua ntej, kuv yuav tsum piav qhia txhua pawg ib qho zuj zus. Cia peb saib. Cat5 laus dua, tej zaum txog li 100 Mbps? Tab sis Cat5e tau txhim kho, txhawb nqa txog li 1 Gbps. Tom qab ntawd Cat6 tuaj yeem ua 1 Gbps dhau qhov deb ntev dua, tej zaum 10 Gbps tab sis luv dua. Cat6a tau txhim kho, yog li kev ua tau zoo dua, tej zaum 10 Gbps dhau 100 meters. Cat7 yog shielded, ceev dua, tab sis siv cov connectors sib txawv? Thiab Cat8 yog rau cov chaw khaws ntaub ntawv, ceev heev tab sis luv dua.

Tos, kuv xav tau cov lus qhia meej. Cia kuv kuaj kuv lub cim xeeb. Cat5e yog 1 Gbps txog li 100 meters. Cat6 ua tau 10 Gbps txog li 55 meters. Cat6a txuas ntxiv mus txog 100 meters rau 10 Gbps. Cat7 raug ntsuas rau 10 Gbps txog li 100 meters thiab tej zaum yuav muaj zaus siab dua. Cat8 yog tsim los rau 25 lossis 40 Gbps txog li 30 meters. Tsis tas li ntawd, kev tiv thaiv yog ib qho tseem ceeb; cov pawg siab dua muaj kev tiv thaiv ntau dua los txo kev cuam tshuam.

Kuv kuj yuav tsum hais txog qhov sib txawv ntawm kev tsim kho, xws li UTP (unshielded twisted pair) vs. STP (shielded). Cat5e feem ntau yog UTP, thaum Cat6a thiab siab dua yuav siv kev tiv thaiv. Cat7 siv GG45 connectors lossis TERA, tab sis tseem sib xws nrog RJ45. Tos, qhov ntawd puas yog? Tej zaum Cat7 feem ntau siv RJ45 tab sis muaj kev tiv thaiv ntau dua. Cat8 yeej siv RJ45.

Cov ntawv thov kuj tseem ceeb thiab. Piv txwv li, Cat5e rau cov tes hauj lwm hauv tsev, Cat6 rau cov chaw ua haujlwm, Cat7 rau kev lag luam, thiab Cat8 rau cov chaw khaws ntaub ntawv. Tus nqi yog lwm yam; cov pawg siab dua kim dua. Kev tiv thaiv yav tom ntej yuav yog qhov yuav tsum xav txog. Tsis tas li ntawd, qhov ntev ntawm cov xov hlau thiab seb nws puas yog cov xov hlau khov kho lossis cov xov hlau txuas. Auj, yog lawm, cov xov hlau khov kho yog rau kev teeb tsa ruaj khov, cov xov hlau txuas rau cov xov hlau txuas.

Kuv yuav tsum tau teeb tsa phau ntawv qhia nrog cov ntu rau txhua hom cable, cov lus qhia tseem ceeb (ceev, bandwidth, nrug), kev tiv thaiv, daim ntawv thov, thiab daim ntawv sib piv. Tom qab ntawd suav nrog kev txiav txim siab yuav khoom xws li kev xav tau daim ntawv thov, kev tiv thaiv yav tom ntej, peev nyiaj, ib puag ncig (kev cuam tshuam suab nrov), thiab hom kev teeb tsa (khoom khov vs. hlua).

Tos, kuv yuav tsum xyuas ob zaug seb qhov ceev thiab qhov deb tshaj plaws yog dab tsi. Cia kuv xyuas kom meej: Cat5e yog 1 Gbps ntawm 100 MHz dhau 100m. Cat6 yog 1 Gbps txog 100m, 10 Gbps txog 55m. Cat6a yog 10 Gbps ntawm 500 MHz dhau 100m. Cat7 yog 10 Gbps ntawm 600 MHz dhau 100m, thiab Cat7a txog 1000 MHz. Cat8 yog 25/40 Gbps ntawm 2000 MHz txog 30m. Tsis tas li ntawd, Cat7 thiab 8 muaj cov kev cai tiv thaiv nruj dua.

Xws li qhov bandwidth (MHz) yog qhov tseem ceeb vim tias qhov ntawd cuam tshuam rau lub peev xwm xa cov ntaub ntawv. Cov connectors: Cat8 siv RJ45, tab sis cov Cats ua ntej yuav muaj ntau hom kev tiv thaiv sib txawv. Tsis tas li ntawd, kev sib raug zoo nrog cov khoom siv uas twb muaj lawm. Piv txwv li, siv Cat6a nrog Cat5e jacks yuav tsis siv tag nrho lub peev xwm.

Kuv yuav tsum hais tias cov pawg siab dua txhawb nqa cov bandwidths siab dua thiab yog li ntawd zoo dua rau cov tes hauj lwm ceev ceev, tab sis tej zaum yuav overkill rau kev siv yooj yim. Tsis tas li ntawd, qhov sib txawv ntawm lub cev xws li tuab thiab lub vojvoog khoov. Cat6a tuab dua thiab tsis yooj ywm dua Cat5e.

Hauv kev txiav txim siab yuav khoom, cov yam xws li kev xav tau tam sim no piv rau yav tom ntej, ib puag ncig (kev lag luam uas muaj kev cuam tshuam piv rau tsev), thiab seb lawv puas xav tau PoE (Power over Ethernet), cov pawg siab dua twg yuav txhawb nqa zoo dua.

Kuv xav tau kom paub tseeb tias phau ntawv qhia no yooj yim to taub, tsis txhob siv cov lus siv thev naus laus zis ntau dhau, tab sis tseem muaj cov ntaub ntawv qhia txog ntau yam. Tej zaum yuav muaj cov lus qhia luv luv thaum pib, tom qab ntawd muaj cov ntu qhia ntxaws ntxaws. Tsis tas li ntawd, muaj cov ntaub ntawv siv feem ntau los pab cov nyeem ntawv txiav txim siab seb lawv xav tau dab tsi.

Tos, kuv yuav tsum xyuas seb Cat7 puas tau lees paub los ntawm TIA/EIA cov qauv lossis yog tias nws yog ISO tus qauv. Vim tias qee zaum Cat7 tsis tau txais kev pom zoo dav hauv qee thaj chaw. Cat6a thiab Cat8 yog tus qauv ntau dua. Qhov ntawd yuav yog ib qho taw tes uas yuav tsum hais txog hauv kev txiav txim siab, xws li kev sib raug zoo nrog cov qauv uas twb muaj lawm.

Thiab, qhov sib txawv ntawm tus nqi. Cat5e pheej yig tshaj, ces Cat6, Cat6a, Cat7, Cat8 kim tshaj plaws. Yog li ntawd, nyiaj txiag yog ib qho tseem ceeb. Rau feem ntau cov neeg siv hauv tsev, Cat5e lossis Cat6 txaus. Rau cov tsev ntse uas muaj ntau yam khoom siv, tej zaum Cat6. Rau cov chaw khaws ntaub ntawv, Cat8.

Kev siv av hauv av tej zaum yuav yog teeb meem nrog cov xov hlau uas muaj kev tiv thaiv; yog tias tsis tau siv av hauv av kom raug, kev tiv thaiv tuaj yeem ua rau muaj teeb meem. Yog li ntawd, kev teeb tsa cov xov hlau uas muaj kev tiv thaiv yuav tsum muaj cov txheej txheem zoo.

Hauv kev xaus lus, phau ntawv qhia yuav tsum qhia txog txhua hom cable cov lus qhia, piv rau lawv, thiab coj tus nyeem ntawv raws li lawv cov kev xav tau tshwj xeeb: qhov ceev xav tau, qhov deb, ib puag ncig, peev nyiaj, thiab cov phiaj xwm yav tom ntej.
