Tam sim no DAC thiab AOC cable tau dav siv, lawv cov khoom siv hlau sib txawv, tab sis txoj haujlwm yog tib yam.Tus neeg siv khoom yuav tsis meej pem yuav ua li cas xaiv vim qhov ua haujlwm zoo ib yam.Lawv qhov zoo thiab qhov tsis zoo yog dab tsi?Ntawm cov neeg siv khoom thov, cia peb tham txog qhov zoo thiab qhov tsis zoo ntawm DAC thiab AOC cable!
Active optical cable (AOC)yog siv rau luv luv-ntau-kab cov ntaub ntawv kev sib txuas lus thiab interconnect daim ntaub ntawv.Feem ntau, cov xaim xaim ntawm kev sib txuas lus kho qhov muag yuav tsum yog ib feem ntawm passive, tab sis AOC yog qhov zam.AOC muaj xws li multimode optical fiber, fiber ntau optic transceivers, tswj nti thiab modules.Nws siv hluav taws xob-rau-kho qhov muag hloov dua siab tshiab ntawm lub cable xaus los txhim kho kev ceev thiab kev ua haujlwm deb ntawm lub cable yam tsis muaj kev cuam tshuam kev sib raug zoo nrog cov qauv hluav taws xob cuam tshuam.Txij li thaum tib neeg xav tias yuav muaj cov ntaub ntawv ntau ntxiv ntawm lawv lub ntsis ntiv tes, peb cov kev sib txuas lus yuav tsum tau nrawm dua, thiab AOC yog ib qho kev daws teeb meem zoo tshaj plaws los daws qhov teeb meem no.Piv nrog rau kev txuas ncaj qha tooj liab cable rau cov ntaub ntawv xa mus, AOC muab ntau qhov zoo, xws li lub teeb yuag, kev ua haujlwm siab, kev siv hluav taws xob tsawg, kev sib cuam tshuam tsis zoo, EMI kev tiv thaiv thiab yoog raws.Tam sim no, AOC tau siv dav hauv ntau qhov chaw nrog rau kev txhawb nqa cov ntaub ntawv ib txwm muaj los mus rau hauv kev sib txuas kho qhov muag.
Raws li cov khoom siv hlau, tuaj yeem muab faib ua:
Direct Txuas Cable, suav nrog active thiab passive DAC cable
Active Optical Cable(AOC)
DAC Qhov Zoo:
※Siab dua cov ntaub ntawv kis tus nqi: Lub DAC cable tuaj yeem txhawb nqa cov ntaub ntawv xa mus los ntawm 4Gbps mus rau 10Gbps, siab dua li ib txwm siv tooj liab cable.
※Strong interchangeability:Nrog rau txoj kev loj hlob ntawm tooj liab technology, DAC cable thiab optical transceiver yog interchangeable thiab kub swappable.
※Tus nqi qis:Copper cable yog pheej yig dua li fiber ntau, siv DAC cable yuav txo cov cos.
※Zoo thermal dissipation:Lub DAC cable yog ua los ntawm cov tub ntxhais tooj liab thiab muaj cov cua kub zoo.
DAC Disadvantages:
※ Kev sib kis luv luv, hnyav hnyav, ntim loj, yooj yim tswj.
※ Muaj kev cuam tshuam rau electromagnetic cuam tshuam, xws li cov lus teb tsis zoo thiab degradation thiab lwm yam.
AOC Qhov Zoo:
◆Loj dua bandwidth:Kev hloov kho khoom siv tsis tas yuav tsum muaj, nrog kev nce mus txog 40Gbps.
◆Lub teeb:Ntau lub teeb dua DAC cable.
◆Tsawg electromagnetic cuam tshuam:vim optical fiber ntau yog dielectric, nws tsis yooj yim rau cuam tshuam los ntawm electromagnetic cuam tshuam.
AOC Disadvantages:
Piv nrog rau DAC cable, tus nqi ntawm AOC cable yog siab dua.
