Dab tsi yog qhov txawv ntawm CAT5E thiab CAT6 hauv cov tsev txawj ntse

 

 

Qhov txawv ntawv yog dab tsiCAT5E, CAT6thiab CAT6A hauv kev ua haujlwm ntawm lub system thiab network thov?

 

1. CAT5E thaiv lub cev bandwidth: 100MHz, CAT6 thaiv lub cev bandwidth: 250MHz;

 

Cov lus piav qhia: qhov loj dua ntawm cov kab nrig ntawm lub cev, lub siab dua kis tau txais kev txhawb nqa.

 

2. CAT5E cable feem ntau siv 24AWG xaim ntsuas lub xov tooj (txog tooj liab tub ntxhais txoj kab uas hla: 0.51 hli), thiab CAT6 cov xov tooj feem ntau siv 23AWG hlau xov (tooj liab tub ntxhais txoj kab uas hla li 0.57 hli);

 

Cov lus piav qhia: cov tuab tooj liab me dua, ua kom zoo dua rau kev coj ua, thiab lub teeb liab me me rau ntawm kab. Hauv cov ntawv thov PoE, 23AWG muaj qhov zoo dua li 24AWG hauv kev hloov khoom siv lub zog.

 

3. Qhov siab tshaj plaws cov ntaub ntawv sib kis tau txhawb nqa los ntawm CAT5E kev tshawb xav xov hluav taws xob yog 1200Mbps, thiab qhov siab tshaj plaws cov ntaub ntawv sib kis tau txhawb los ntawm CAT6 thaiv kev tshawb xav yog 2400Mbps;

 

Cov lus piav qhia: qhov siab dua cov ntaub ntawv hloov chaw, qhov loj dua cov bandwidth lub cev.

 

4. Lub 10GBASE-T 10G Ethernet daim ntawv thov cov qauv uas cov xaim CAT5E tsis txhawb, thiab 10GBASE-T Ethernet daim ntawv thov tus qauv uas xaim xaim CAT6 tuaj yeem txhawb nqa, tab sis kev kis mus rau lwm qhov txwv thiab tsis pub tshaj 37 meters.

 

Cov lus piav qhia: Pawg 6 cabling lub cev tuaj yeem ua kom tau raws li daim ntawv thov yuav tsum tau ntawm 10 Gigabit Ethernet hla kev ncua deb, thaum qeb 5 tsis tuaj yeem txhawb nws.

 

5. CAT6 cables feem ntau lees txais tus qauv ntoo khaub lig qauv los txo kev sib tsoo ntawm cov khub. Nws (NEXT) ze-kawg crosstalk kev ua tau zoo Performance index yog 5-10dB siab dua li ntawm CAT5E tsis muaj tus qauv thav duab (1-100MHz);

 

Cov lus piav qhia: Minimizing crosstalk nruab nrab ntawm khub yog qhov tseem ceeb tshaj plaws ua ntej rau kev ruaj khov thiab siab ceev kis ntawm cov ntaub ntawv hauv cov xov hluav taws xob.

 

Qiv sib piv qhov sib txawv ntawm qhov tau hais los ntawm ob theem ntawm kev ua kab hlau, Qeb 6 qhov hluav taws xob tsis yog tsuas yog siab dua Pawg 5 cabling hais txog kev ua haujlwm ntawm lub cev thiab hluav taws xob, tab sis kuj tseem siab dua Qeb 5 kev xaim hluav taws xob hauv cov lus hais ntawm kev kub ceev thiab ruaj khov cov ntaub ntawv xa mus. Nyob rau tib lub sijhawm, raws li qeb 6 kev lag luam cabling txuas ntxiv mus rau qhov loj, kev nce qib loj ntawm qeb 6 cov khoom lag luam tsim cov khoom lag luam loj ntawm cov khoom lag luam 6 cov khoom lag luam, ua cov nqi qeb 6 cov khoom siv hluav taws xob tsis pub ntau dua tus nqi ntawm dua 5 pawg.

 

Qhov txawv ntawv yog dab tsiCAT5E, CAT6thiab CAT6A hauv kev ua haujlwm ntawm lub system thiab network thov?

 

Tom ntej no, ntawm no yog cov lus piav qhia luv luv ntawm qhov sib txawv hauv cov khoom lag luam ntawm CAT6 thiab CAT6A cabling systems:

 

1. CAT6 thaiv lub cev bandwidth: 250MHz, CAT6A thaiv lub cev bandwidth: 500MHz;

 

Cov lus piav qhia: qhov loj dua ntawm cov kab nrig ntawm lub cev, lub siab dua kis tau txais kev txhawb nqa.

 

2. CAT6 cable voj tsis kam (ntawm 20â ƒ ƒ) 155 ohm / km, tus nqi NVP: 69%;

 

CAT6A cable voj tsis kam (ntawm 20 ° C) 150 ohm / km, NVP tus nqi: 76%;

 

Cov lus piav qhia: Qhov me dua ntawm cov tooj liab lub voj tsis kam, qhov zoo dua rau kev coj ua, thiab lub teeb liab me me rau ntawm txoj kab. Tus nqi ntawm NVP tus nqi yog qhov feem pua ​​ntawm lub teeb liab hluav taws xob sib kis hauv tooj liab nruab nrab kom sib npaug rau qhov ceev ntawm lub teeb nyob hauv lub tshuab nqus tsev. Qhov siab dua NVP tus nqi, qhov nrawm dua kis tau ntawm lub teeb liab hluav taws xob hauv nruab nrab.

 

3. Lub 10GBASE-T 10 Gigabit Ethernet daim ntawv thov cov qauv kev txhawb nqa los ntawm CAT6 cabling, tab sis kev sib kis tau tsis pub dhau, tsis pub tshaj 37 metres (thiab qhov yuav tsum tau ntxiv rau qhov kev xeem sab nraud los ntsuas qhov ua tau zoo dua ntawm Pawg 6 cabling system tawm tsam sab nraud hluav taws xob cuam tshuam). CAT6A cabling tuaj yeem pab txhawb 10GBASE-T Ethernet daim ntawv thov cov qauv, uas ua tau raws li 100-meter ntau daim qauv thov tsis tas yuav muaj kev xeem sab nraud sab nraud.

 

Cov lus piav qhia: CAT6A cabling system tuaj yeem ua tiav cov ntawv thov yuav tsum tau ntawm 10 Gigabit Ethernet ntawm qhov deb ntawm 100 metres, thiab muaj ntau qhov tsis xws luag hauv kis ntawm 10 Gigabit Ethernet los ntawm CAT6 cabling system.

 

4. CAT6A cable feem ntau siv cov txheej txheem ntawm txhuas ntawv ci shielding thiab txhuas ntawv ci tag nrho cov ntaub thaiv kom ua tiav cov txiaj ntsig tsis zoo tiv thaiv kev tiv thaiv sab nrauv hluav taws xob cuam tshuam thiab hla ntawm cov khub. Lub laj kab hla nruab nrab ntawm rau (6) hom tsis muaj kev sib txuam ntawm tus ntoo khaub lig qauv qauv yog 15-35dB siab dua nyob rau hauv thaj tsam ntawm (1-250MHz).

 

Cov lus piav qhia: Minimizing crosstalk ntawm khub thiab kom tsis txhob muaj hluav taws xob sab nraud cuam tshuam los ntawm cov xov tooj hluav taws xob yog qhov tseem ceeb tshaj plaws rau kev nkag mus rau qhov ruaj khov thiab kev kub ceev kis ntawm cov ntaub ntawv hauv kab hluav taws xob.

 

Cov kab hluav taws xob sib xyaw ua ke tau tsim tawm rau ntau tshaj 20 xyoo. Nrog rau kev nrov hauv kev siv network hauv cov teb ntau, cov naj npawb ntawm cov chaw nres nkoj tau nce siab zuj zus. Thiab nrog cov kev txhim kho txuas ntxiv ntawm cov ntaub ntawv thev naus laus zis, cov neeg siv tau muaj siab dua thiab siab dua qhov xav tau ntawm kev sib txuas network. Txhawm rau pab txhawb kev tsim kho kom muaj kev sib koom tes ceev, network cabling system kuj tau txuas ntxiv los ntawm thawj peb hom kab ke rau niaj hnub no kev them nyiaj yug rau 10 Gigabit kis. CAT6A (Cat 6), tuaj yeem muab cov kab rov tav kis ntawm 10 Gigabits thiab 10Gbps. Yog li tam sim no, txoj kev sib kis ntawm tooj liab cabling yog tsis muaj daim ntawv thov bottleneck.
