10GBASE-T vs SFP + vs DAC: yuav ua li cas xaiv?

Txheej txheem cej luam ntawm 10GBASE-T tooj liab module, SFP + optical module thiab kev kub ceev cable:

Dab tsi yog 10GBASE-T tooj liab cable SFP + transceiver？

10GBASE-T SFP + tooj liab module yog tsim tshwj xeeb rau kev sib txuas lus kub ceev ntawm 10Gb Ethernet, uas tuaj yeem kis tau dua tus miv 6A / 7 network cable. Nws yog thawj 10g module muab 10Gb / s nrawm dua Ethernet tooj liab cable thiab ua tau raws li sff-8431 thiab sff-8432 MSA cov qauv.

Dab tsi yog 10GbE SFP + optical module？

10GbE SFP + kho qhov muag kuj tseem siv tau rau 10G kev sib txuas lus hauv network nrog qhov chaw sib kis tau ntev tshaj 100km. Nws muaj ntau yam qauv, xws li 10gbase-sr, 10gbase-lr, 10gbase-er, 10gbase-zr, thiab lwm yam.

Piv nrog rau XFP optical module thaum ntxov, qhov loj me ntawm SFP + raug txo tsawg dua 30%, uas yog qhov zoo tib yam ntawm qhov tseeb ntawm 1-4g optical module. SFP + tsuas yog khaws qhov yooj yim electro-optic thiab photoelectric hloov pauv kev ua haujlwm, thiab txo qhov SerDes, CDR, EDC, MAC thiab lwm cov teeb liab tswj ua haujlwm hauv tus qauv XFP qub, yog li yooj yim tsim ntawm 10G Optical module thiab txo qhov lub zog noj. Nrog rau qhov zoo ntawm kev siab, kev siv hluav taws xob tsawg thiab qis dua kev tsim kho cov nqi, cov khoom lag luam tau siv dav hauv 10 Gigabit Ethernet optical fiber data sib txuas lus teb, thiab yog cov khoom tseem ceeb ntawm 10 Gigabit module.

Cov txiaj ntsig zoo ntawm SFP + optical module

1. Qhov loj ntawm SFP + yog qhov me dua ntau dua li cov uas X2 thiab pob (tib yam li qhov loj ntawm SFP);

2. Nws tuaj yeem txuas ncaj qha nrog XFP, X2 thiab xenpak ntawm tib hom;

3. Tus nqi qis dua XFP, X2, xenpak cov khoom lag luam.

4. Tus nqi siv tau zoo twisted khub tooj liab cabling, tus nqi qis kawg 10GbE Ethernet xa mus

5. Nrog rau cov kev ua haujlwm dhau los ntawm Base-T network tsis siv neeg kev sib tham rov qab sib raug zoo, rov qab khi rau 10GbE

6. Teb sib tw xov hlau sib txuas nrog cov paub txuas RJ-45 cov txuas

7. Kev kawm raws li kev tsim ua ntej dhau' cov txuj ci yooj yim thiab cov txuj ci kev lag luam uas twb muaj lawm

8. Txoj hlua cable ntev li 100 meters yog txaus los txhawb yuav luag txhua cov ntaub ntawv nruab nrab

9. Txhawb kev txhawb ntxiv rau thaj chaw ib puag ncig

SFP + DAC txoj kev kub ceev cable？

DAC txhais tau tias ncaj qha cable. 10g SFP + DAC high-speed cable yog tooj liab sib txuas ua ke raws li kev siv pheej yig dual tub ntxhais hluas tooj liab cable los ua ke ntawm SFP + MSA (muaj ntau qhov txheej txheem), nrog rau ob qho kawg ntawm cov tooj liab sib txuas nrog cov xaim txuas ntawm SFP + DAC. Nws muaj qhov zoo ntawm kev siv hluav taws xob tsawg, kev siv tus nqi qis thiab qeeb qeeb. Nws yog qhov kev xaiv zoo tshaj plaws rau daim ntawv thov ntawm luv luv kev kub ceev 10 Gigabit Ethernet hauv cov ntaub ntawv nruab nrab niaj hnub. Raws li qhov tshwm sim, cov xov tooj loj ntawm SFP + cov xaim feem ntau siv rau cov khoom sib txuas rau cov pob nyem hluav taws xob thiab kev sib txuas luv luv ntawm kev hloov chaw nres nkoj ntawm cov servers thiab chaw cia hauv racks thiab Ethernet cuam tshuam. Kev kub ceev ntawm 10G SFP + DAC adopts silicon chip los txhim kho kev ua haujlwm ntawm cov cable. Yog tias tsis muaj daim phiaj, cov cables suav tau tias yog" passive" txuas xov tooj. DAC txoj hlua hluav taws xob muaj zog luv dua 7 metres yog passive, thaum cov xaim hluav taws xob ntev dua 7 metres yog nquag. Kev kub ceev cable Cheebtsam tuaj yeem ntsib thiab dhau ntawm kev ua tau zoo thiab kev cia siab ntawm Gigabit Ethernet thiab fiber channel cov qauv kev lag luam. Nws yog qhov ua haujlwm siab, tsis raug nqi I / O tov rau 10Gb Ethernet thiab 10g fiber ntau cov ntawv thov.

Dab tsi yog qhov sib txawv ntawm 10GBASE-T tooj liab module, SFP + optical module thiab high-speed cable ntawm SFP + DAC?

Yeem& amp; rov qab tau zoo

Lub 10GBASE-T tooj liab module siv sib cuam tshuam 10GBASE-T thev naus laus zis, tuaj yeem siv RJ45 txuas thiab tuaj yeem sib hloov ntawm 10/100/1000 Mbps thiab 10g ceev. Hauv lwm lo lus, 10GBASE-T tooj liab cov qauv txuas rov qab tau yooj yim nrog cov tooj liab network network li qub. 10GbE SFP + optical module tuaj yeem siv hauv 10G Ethernet thiab 10g fiber channel, tab sis nws tsis sib haum nrog tooj liab cabling system, tab sis qee zaum nws tuaj yeem siv hauv 1g fiber ntau lub network. Raws li rau SFP + DAC txoj hlua hluav taws xob high-speed cable, nws tsis sib haum nrog qhov hloov Gigabit Ethernet uas twb muaj lawm, tsuas yog rau qhov txuas ntawm 10G Ethernet hloov.

Ncua

Nrog kev nce ntawm Private Cloud Application siv, qhov kev thov rau cov tsis tshua muaj nyob hauv cov chaw loj cov ntaub ntawv yog loj hlob sai. Tsawg latency yog qhov tseem ceeb los xyuas kom lub sijhawm teb ceev thiab txo CPU kaw lub voj voog, uas tuaj yeem txhim kho cov ntaub ntawv ntawm qhov chaw ua haujlwm thiab ROI. 10GBASE-T tooj liab module siv PHY tus qauv, thiab tuaj yeem xa cov ntaub ntawv ntawm tooj liab cable yam tsis muaj qhov yuam kev los ntawm kev siv cov lej thaiv. Tus qauv txiav txim siab tias cov transceiver sijhawm ntawm 10GBASE-T tooj liab module yog 2.6 microseconds. Lub SFP + fiber ntau tsis tau sau los ntawm cov khoom siv hluav taws xob yooj yim. Lub sijhawm qeeb ntawm txhua qhov txuas yog li 300 nanoseconds. Raws li tuaj yeem pom los ntawm cov lus hauv qab no, qhov qeeb ntawm SFP + fiber ntau qis dua qhov uas lwm cov khoom lag luam ob.

Kev hloov mus deb

Qhov siab tshaj qhov kis tau tus mob ntawm 10GBASE-T tooj liab module ntawm cat6a lossis cat7 network cable yog 100m, thiab qhov chaw xa hluav taws xob ntau ntawm 10GbE SFP + optical module ntawm ib hom kho qhov muag fiber ntau yog 100km. Txawm li cas los xij, SFP + DAC high-speed cable tuaj yeem tsuas kis tau 10 metres ntawm feem ntau, uas zoo dua rau cov xaim txuas nyob rau sab hauv thiab ntawm cov racks. Yog hais tias qhov kis tau mus deb tsis yog qhov tseem ceeb uas yuav tsum tau txiav txim siab, txoj kab hluav taws xob loj ntawm SFP + DAC muaj qis zog siv hluav taws xob tsawg dua thiab qeeb qeeb, yog li nws yog qhov zoo tshaj plaws cabling tov rau cov ntaub ntawv chaw.

Nqi

10GBASE-T RJ45 modules feem ntau siv cov cat6a lossis cat7 network cable rau xov hluav taws xob, uas yog pheej yig dua li siv cov fiber ntau optical cabling rau 10GbE SFP + optical modules. Hauv cov ntaub ntawv chaw, ntau pua ntawm cov xov tooj feem ntau xav tau, thiab lub network cable pheej yig tuaj yeem txuag nqi ntau. Ntxiv mus, 10GBASE-T tooj liab module tuaj yeem ua kom zoo tshaj plaws ntawm kev siv cov tooj liab kab ke siv hluav taws xob thaiv, thiab tseem txuag tau ntau yam kev siv nyiaj. 10g SFP + kho qhov muag kho qhov muag yuav tsum tau siv cov khoom siv sib luag kim lossis cov khoom siv fiber ntau sib tw rau kev xa, thiab cov nqi saib xyuas ntawm optical fiber cabling system yog siab. SFP + DAC high-speed cable yog tus nqi qis tshaj ntawm peb cov khoom lag luam, qhov tsis zoo tsuas yog qhov kev sib kis tau raug txwv tsawg heev.

Cov lus hauv qab no qhia cov teeb meem yooj yim ntawm 10GBASE-T SFP + tooj liab module, 10GbE SFP + optical module thiab high-speed cable ntawm SFP + DAC.

Hauv cov ntsiab lus, 10GBASE-T tooj liab cov qauv, SFP + optical modules, thiab SFP + DAC txoj kev kub ceev sib txawv sib txawv hauv qhov ua tau yooj yim, rov qab tsis tau, qhov deb, daim ntawv thov latency, thiab tus nqi. Koj tuaj yeem xaiv cov khoom kom raug raws li koj qhov kev xav tau ntawm lub network. Nws yog tsim nyog sau cia tias nrog kev nrov ntawm cov fiber ntau cabling system, tooj liab cabling system yuav maj mam thim tawm los ntawm kev ua lag luam, yog li 10GBASE-T tooj liab tus qauv yuav maj mam rho tawm los ntawm kev ua lag luam. Nrog rau kev txo nqi ntawm tus nqi thiab lub zog noj, 10GbE SFP + optical module yuav dhau los ua qhov kev daws teeb meem zoo rau cov ntaub ntawv chaw network.

HTF' s khoom yog customized, qhov zoo tshaj yog lav, thiab cov khoom siv tau ntshuam.
