Qhov sib txawv ntawm CAT5e network cable thiab CAT6 network cable yog dab tsi?

 

CTC Connexions yog cov chaw tsim khoom ntawm cov kab hluav taws xob, cov xov hlau thiab cov coaxial cable tau 17 xyoo.

"Qeb 5e" yog hais txog qeb 5e khub tsis tuaj yeem tuav tus kheej.

Cia peb saib qhov sib txawv ntawm Super qeb 5 network cable thiab Super qeb 6 network cable.

Cov menyuam tsis muaj hlua khi khi ua ke ntawm cov hlua khi ob peb sib txuas thiab cov hnab yas ua ke. Qeb tsib yog hais txog tsib qib sib txawv zoo tau teev tseg los ntawm International Hluav Taws Xob Kev Lag Luam Kev Koom Tes rau kev sib ntswg.

 

Qeb 5e unshielded twisted pair cable yog ib qho cable uas pom tom qab kev txhim kho ntawm feem ntawm kev ua tau zoo ntawm Qeb 5 uas muaj qhov thaiv tsis muaj kab nrig khub. Ntau cov haujlwm tsis dhau, xws li ze-kawg crosstalk, attenuation crosstalk ratio, rov qab poob, thiab lwm yam zoo dua, tab sis nws cov kis tau tus mob tseem tseem 100MHz.

 

Cov qeb 5 twisted-pair cable kuj tseem siv 4 winding khub thiab 1 tensile xaim. Cov xim ntawm khub yog tus zoo ib yam li ntawm qeb 5 cov khub, uas yog xim txiv kab ntxwv dawb, txiv kab ntxwv, dawb ntsuab, ntsuab, xiav dawb, xiav, thiab dawb. Xim av thiab xim av. Txoj kab uas hla ntawm tooj liab tooj liab hlau yog 0.51 hli (lub xov ntsuas lub xov tooj yog 24AWG), txoj kab uas hla ntawm hlau kab yog 0.92mm, thiab lub taub ntawm UTP cable yog 5 hli. Txawm hais tias Qeb 5e unshielded twisted khub tseem tuaj yeem muab tau li 1000Mb / s kis kab mob, nws feem ntau xav tau kev txhawb nqa ntawm cov cuab yeej tshwj xeeb kim. Yog li no, feem ntau nws tsuas yog siv rau 100Mb / s ceev Ethernet coj los txuas rau lub desktop hloov mus rau lub khoos phis tawm. Yog tias koj tsis mus txhim kho koj lub network mus rau Gigabit Ethernet yav tom ntej, koj kuj yuav siv tau Pawg 5e unshielded twisted khub hauv kab rov tav cabling.

 

"CAT6"yog hais txog qeb rau khub uas tsis muaj kev tiv thaiv zoo rau ob tug khub

 

Cov kev txwv ntawm 6 yam ntawm qhov tsis raug khi khi ua kom sib tw tau muaj kev txhim kho tau zoo heev, thiab qhov bandwidth kuj tau txuas ntxiv rau 250MHz lossis siab dua. Pawg 6 twisted pair cables txawv ntawm qeb 5 lossis Qeb 5 twisted khub nyob rau hauv tsos thiab qauv. Tsis tsuas yog ua rau cov kab hluav taws xob tsis ruaj khov nce, plaub plaub ntawm cov sib txig sib luag tau muab tso rau hauv plaub ntawm tus ntoo khaub lig ncej. Tsis pub dhau ib qho zawj, thiab txoj kab uas hla ntawm lub cable tseem thicker.

 

Tus ntoo khaub lig ncej hauv nruab nrab ntawm lub cable tig nrog qhov hloov ntawm qhov ntev, thiab plaub txoj xov sib tw yog clamped nyob rau hauv qhov zawj ntawm thav duab kom muaj qhov chaw sib txheeb ntawm cov plaub sib luag los txhim kho qhov sib npaug ntawm cov yam ntxwv thiab cov xov paj sib txuas ntawm lub Cov. Tsis tas li ntawd, xyuas kom meej tias qhov kev sib txig ntawm txoj hlua ntawm lub cable tsis puas thaum lub sijhawm txheej txheem teeb tsa. Qhov txoj kab uas hla ntawm liab tooj liab hlau ntawm qeb 6 unshielded twisted khub yog 0.57 hli (lub xov hlau qhov ntsuas yog 23AWG), txoj kab uas hla ntawm hlau insulated yog 1.02mm, thiab txoj kab uas hla ntawm UTP cable yog 6.53mm.

 

Qhov twg yog qhov zoo dua, CAT5e network cable lossisCAT6 network cable?

 

Raws li qhov sib txawv hluav taws xob sib txawv, kev sib tw ntawm tus khub tuaj yeem muab faib ua peb hom, tsib hom, super tsib hom, rau hom thiab xya hom kev sib txig sib luag. Tus nqi ntawm ntau yam ntawm cov sib ntswg sib txuas-cable sib txawv heev lossis txawm tias txawv, thiab qhov uas tau txais ntawm daim ntawv thov kuj tseem sib txawv.

 

Tsuas yog hais tias lub suab tsoos system tseem siv Qeb 3 sib txuam, network cabling yog tam sim no qhov kev siv Qeb 5 lossis Qeb 6 tsis raug txhaws sib tw. Txawm hais tias Qeb 5 tsis tau ua ke rau cov khub sib koom ua ke tseem tuaj yeem txhawb nqa 1000Base-T, nws tau maj mam tawm ntawm cov kev lag luam cabling vim tias nws yuav luag zoo li Qeb 5 tsis tau ua ke rau cov khub sib koom ua ke ntawm nqe.

 

   Txawm hais tias tus nqi ntawmPawg 6 unshielded twisted khub yog qhov siab heev, nws maj mam dhau los ua qhov tshiab nyiam ntawm kev sib txuas ntawm cov xov hlau vim nws txoj kev sib raug zoo heev nrog Pawg 5 cabling system thiab muaj peev xwm txhawb 1000Base-T zoo heev. CAT7 daim phiaj thaiv thaiv kab nrig yog cov kev siv hluav taws xob tshiab. Txawm hais tias nws muaj qhov ua tau zoo tshaj plaws, nws tseem kim. Kev tsim kho yog qhov nyuaj thiab muaj tsawg dua cov khoom lag luam rau xaiv, yog li nws tsis tshua muaj siv hauv cov phiaj xwm hlau.

 

CAT6unshielded ntswj Hlab hlau can support Gigabit Ethernet very well and achieve a transmission distance of 100m. Therefore, the Pawg 6 wiring system is widely used in the wiring of the sub-server computer room and the horizontal wiring that retains the ability to upgrade to Gigabit Ethernet. According to the international cabling standard ISO 11801, the life expectancy of a cabling system is at least 10 years. As a long-term basic investment, integrated cabling should fully consider the potential needs of the network and the development of the cabling system. Therefore, it is recommended to choose six types of products to build the cabling system under the condition of capital permitting.

 

Yog tias koj xav txog cov ntawv thov lub npe yav tom ntej ntawm lub network, raws li qhov tsim kho cov khoom siv hluav taws xob ntau tshaj plaws, vim nws feem ntau nyuaj hloov kho thiab hloov tom qab kev teeb tsa ntawm cov kab. Yeej, cov kab hluav taws xob yuav tsum siv tus qauv rau tsawg kawg 10 xyoo thiab tuaj yeem pab txhawb 4 txog 5 tiam ntawm kev sib koom tes Cov kev ua tau zoo ntawm cov khoom siv raug hloov kho, yog tias yav tom ntej cov khoom siv network xav tau cable zoo dua ntxiv kom nce cov ntaub ntawv ceev.

 

So, it is inevitable to use Pawg 6 cables to replace Category 5e cables, but these cables are very expensive to rebuild, so even if the price of Pawg 6 products is slightly more expensive than Category 5 products, in order to reduce future network upgrade problems, Six types of products are still worth considering.
