Puas yog DAC Copper lossis Fiber?
DAC cables yog tsim los ntawm Twinax tooj liab coaxial shielded thiab yog lub Hoobkas nruab nrog modules ntawm ob qho kawg txuas nrog cov chaw nres nkoj ruaj.Cov modules tsis tuaj yeem raug tshem tawm ntawm lub cable.Yog li ntawd, tag nrho cov DAC cables yog tsim nyob rau hauv ib tug ntev ntev.High-speed tooj liab cable muaj kev ua tau zoo heev attenuation, tsis tshua muaj latency, thiab tiv thaiv kev cuam tshuam nyob rau hauv high-frequency broadband kis tau tus mob.
Twinax Cable siv rau dab tsi?
Twinax txuas ncaj qha tuaj yeem siv dav hauv cov ntaub ntawv chaw sib cuam tshuam xws li SATA cia khoom, RADI systems, core routers, core keyboards, servers rau 10G / 40G / 100G Ethernet, thiab InfiniBand.Feem ntau hais lus, qhov no ncaj qha txuas tooj liab cable muab cov txiaj ntsig zoo thiab kev ua haujlwm siab rau cov xwm txheej hauv qab no:
• Sab saum toj ntawm Rack(ToR)/Kab nyob ib sab – Txawm tias passive los yog nquag DAC cable yog zoo meej rau luv luv ToR los yog khib-rau-rack kev khiav hauj lwm nrog nqi-zoo pob nyiaj siv.
• Nruab nrab ntawm Kab – Active DACs tej zaum yuav yog ib qho kev daws teeb meem zoo dua hauv daim ntawv thov no, tsuav yog qhov kev sib kis deb tsawg dua 15m.
• Xaus ntawm Kab - DAC cables yog qhov zoo tagnrho rau qhov kawg ntawm kab architectures ntev npaum li qhov kev ncua deb tsis pub dhau 15 meters txwv.
Dab tsi yog qhov txawv ntawm Active thiab Passive DAC Cables?
Qhov sib txawv tseem ceeb ntawm kev siv DAC cable thiab passive DAC cable yog seb lub teeb liab ua tiav lossis tsis ua.Yog tias muaj cov khoom siv hluav taws xob rau cov teeb liab txias hauv lub cable, nws yog "Active DAC".Yog tias tsis yog, nws yog "Passive DAC", vim nws tsis siv hluav taws xob rau cov teeb liab txias.Sib nrug los ntawm cov khoom siv sab hauv, active thiab passive DAC cables kuj txawv ntawm ib leeg hauv qhov txuas ntev.Ib qho passive DAC Twinax cable xa cov teeb liab Ethernet tshaj qhov ntev (0.5 m-5 m), thaum lub zog DAC Twinax cable txhawb kev sib kis ntawm 5 m-10 m rau Ethernet teeb liab.
