AOC Cablevs DAC Cable: Qhov twg zoo dua rau koj

1. DAC thiab AOC Cables muaj dab tsi?
Ob leeg DAC thiab AOC yog cov kev daws teeb meem sib txuas rau cov ntaub ntawv sib txuas thiab feem ntau yog siv rau kev kub ceev, kev ntseeg siab ntawm kev sib txuas thiab kev xa mus los ntawm cov chaw zov me nyuam, cov khoos phis tawj ua haujlwm siab, thiab cov khoom siv loj.Ob leeg ntawm lawv qhov kawg muaj cable sib dhos nrog lub Hoobkas-tawm transceivers, uas txuas nrog cov chaw nres nkoj ruaj nkaus xwb.Dhau li ntawd, DAC thiab AOC cables tuaj yeem tsim nyob rau hauv qhov ntev sib txawv los txhawb cov ntaub ntawv sib txawv, xws li 10G SFP DAC / AOC cable, 25G AOC cable, 40G DAC cable, thiab 100G AOC cable.

2. Pros thiab Cons ntawm DAC Cable

Pros ntawm Direct Txuas Copper Cable

Tus nqi ntau dua - Feem ntau hais lus, tus nqi ntawm cov tooj liab cables qis dua li ntawm fiber ntau optical.Tus nqi ntawm passive tooj liab cables yog 2 mus rau 5 npaug pheej yig dua fiber ntau cables ntawm tib ntev.Yog li ntawd, kev siv cov high-speed cables kuj yuav txo tau cov nqi cabling ntawm tag nrho cov ntaub ntawv chaw.

Kev siv hluav taws xob qis dua - Kev kub ceev DAC (txoj kab txuas ncaj qha) siv hluav taws xob tsawg (lub zog siv yuav luag xoom) vim tias cov kab hluav taws xob tsis tas yuav tsum muaj hluav taws xob.Kev siv hluav taws xob ntawm cov khoom siv tooj liab feem ntau yog nyob ib ncig ntawm 440mW.Yog tias koj siv cov tooj liab txuas ncaj qha los ntawm AOC fiber ntau cables, koj tuaj yeem txuag tau ntau pua txhiab kilowatts ntawm lub zog hluav taws xob.

Nws yog qhov ruaj khov dua-Nws yog tsim los nrog kev sib txuas tsis sib xws ntawm cov khoom siv kho qhov muag thiab kho qhov muag cable, uas txo tus nqi thiab xyuas kom meej tias qhov chaw nres nkoj kho qhov muag tsis raug cov plua plav thiab lwm yam paug.Yog li, DAC tsis tshua muaj kev puas tsuaj.

 Cons ntawm Direct Txuas Copper Cable

Ib qho tsis zoo ntawm DAC cable yog tias nws hnyav dua thiab ntau dua li AOCs.Tsis tas li ntawd, nws muaj kev cuam tshuam ntau dua los ntawm kev cuam tshuam ntawm electromagnetic cuam tshuam thiab attenuation nyob rau hauv qhov kev ncua ntev vim qhov hluav taws xob teeb liab kis ntawm ob qho kawg.

3. Pros thiab Cons ntawm AOC Cable

Pros ntawm AOC

Qhov hnyav dua-Ib qho khoom siv kho qhov muag cable yog tsim los ntawm ob qho khoom siv optical transceivers thiab fiber ntau optic thaj cable, uas nws qhov hnyav tsuas yog ib lub hlis twg ntawm qhov ncaj qha txuas tooj liab cable, thiab qhov ntau yog li ntawm ib nrab ntawm cov tooj liab cable.

Kev ncua ntev-AOC fiber ntau tuaj yeem muab qhov sib kis tau ntev dua thiab ntev txog li 100-300m vim nws cov cua sov zoo dua nyob rau hauv chav tsev computer cov kab hluav taws xob thiab cov kab hluav taws xob me me ntawm kho qhov muag.

Kev ntseeg tau ntau dua - Cov kab hluav taws xob kho qhov muag tsis tshua muaj kev cuam tshuam rau electromagnetic cuam tshuam vim qhov kho qhov muag fiber ntau yog ib hom dielectric uas tuaj yeem txhawb nqa hluav taws xob zoo li qub hauv nws.Qhov kev ua yuam kev me ntsis ntawm cov khoom sib kis tau zoo dua, thiab BER tuaj yeem ncav cuag 10^-15.

Cons ntawm AOC

Lub ntsiab tsis xws luag ntawm AOC active fiber cables yog tias nws yog ib tug kim kim cabling los ua ke daws rau high-density data center tswv.Tsis tas li ntawd, AOCs tsis tshua muaj zog yog tias tsis tswj xyuas kom zoo vim tias lawv sib zog thiab nyias AOCs ntau dua thiab nyias uas ua rau lawv muaj kev puas tsuaj ntau dua yog tias tsis kho kom raug.

4. Thaum twg koj siv AOC Cables?

Txawm li cas los xij, qhov kev ncua deb ntawm ToRs thiab ntug core keyboards feem ntau yog tsawg dua 100m, qhov twg Integrated circuits yog deployed ntom.Yog li ntawd, lub active optical cable yog ib tug zoo cabling kev daws teeb meem rau cov ntaub ntawv kev twb kev txuas vim nws qhov zoo ntawm lub teeb yuag, me me txoj kab uas hla, thiab tswj tau cabling tu.Txij li thaum cov ntaub ntawv chaw muaj nruj specifications ntawm cov teeb liab kis tau tus mob, active optical cable yog zoo dua li ntxaib-axes DAC cable nyob rau hauv lub teeb liab kev ncaj ncees thiab optical coupling tsim, zoo heev txo qhov yuam kev nyob rau hauv lub teeb liab ua.Tsis tas li ntawd, lub siab EMI teeb liab yog ua tiav nyob rau hauv pluggable optical modules, AOC fiber ntau cable muaj ib tug zoo EMI kev ua tau zoo dua DAC cable.Undoubtedly, AOC cable yog koj thawj qhov kev xaiv hauv kev sib txuas ntawm cov keyboards thiab keyboards nyob rau hauv luv luv lossis nruab nrab ncav cuag.

5. Thaum twg koj siv DAC Cables?

Raws li cov ntaub ntawv tshaj tawm los ntawm Facebook, lub server thiab Top-of-Rack keyboards (ToR) yog qhov tseem ceeb ntawm cov ntaub ntawv chaw.Feem ntau hais lus, qhov kev ncua deb ntawm ToR thiab server NIC (Network Interface Card) yog tsawg dua 5 meters.Hauv qhov xwm txheej no, DAC cable yog qhov zoo dua li AOC cables hauv kev hwm ntawm tus nqi, kev siv hluav taws xob, thiab hluav taws xob tawg.Yog li, DAC yog qhov kev xaiv zoo tshaj plaws rau IDC interconnect systems.Dhau li ntawd, ntawm qee lub sijhawm tshwj xeeb, 100G QSFP28 rau 4 * SFP28 DAC yog lwm txoj kev sib txuas ncaj qha raws li tus neeg siv qhov kev thov tshwj xeeb rau cov ntaub ntawv sib txuas.
