Nrog rau txoj kev loj hlob sai ntawm cov tes hauj lwm, cov chaw zov me nyuam tau ntsib cov teeb meem ntawm cov bandwidth siab, muaj kev ntseeg siab thiab tsis tshua muaj latency, thiab yog qhov xav tau ceev ceev ntawm cov nqi siv high-speed interconnection daws teeb meem. Nyob rau hauv luv luv kis tau tus mob, DAC high-speed cable muaj qhov zoo ntawm kev siv hluav taws xob tsawg, tus nqi qis thiab kev yooj yim ntawm kev siv piv rau kev sib xyaw ua ke ntawm optical module ntxiv rau fiber ntau thaj cable, uas yog dav siv hauv cov ntaub ntawv sib txuas.
Qhov zoo ntawm DAC high-speed cables piv rau optical modules
² Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: Cov khoom siv sab hauv ntawm DAC high-speed cable yog ua los ntawm cov tub ntxhais tooj liab, thiab tooj liab muaj cov nyhuv thermal dissipation zoo, uas yog ntau zog txuag thiab kev tiv thaiv ib puag ncig.
² Tsawg zog noj:DAC high-ceev cablemuaj tsawg zog noj, feem ntau hais lus, lub hwj chim noj ntawm optical modules yog ntau tshaj 1W, tab sis lub hwj chim noj ntawm DAC high-ceev cable feem ntau tsawg dua 0.5W.
² Tus nqi qis: DAC high-speed cable optical li yam tsis muaj optical lasers thiab lwm yam khoom siv hluav taws xob, tuaj yeem txuag cov nqi tsim khoom, thiab tooj liab cable yog qis dua tus nqi ntawm fiber ntau, hauv kev xaim DAC high-speed cable tuaj yeem txuag kev siv. ntawm optical fiber ntau, thiaj li ua tiav cov txiaj ntsig ntawm tus nqi qis. Piv txwv li, ob kis tau tus mob nyob deb ntawm 1 meter 100G Cisco hloov interconnection, yog DAC high-speed cable, tsuas yog ib tug 1-meter 100G DAC high-speed cable; Yog hais tias lub optical module ntxiv fiber ntau thaj cable, ob 100G SR4 optical modules thiab ib tug 1-meter 12-core MTP fiber thaj cable, tag nrho cov nqi yog 8 mus rau 10 npaug ntau dua.
Kev piav qhia ntxaws ntawm DAC high-speed cable los ntawm cov qauv
DAC high-speed cable yog tsim los ntawm ib tug cable thiab ob qho khoom siv kho qhov muag.
Nws cov cable siv nyiaj-plated conductors, lub cev ua npuas ncauj polyolefin cov ntaub ntawv rwb thaiv tsev tub ntxhais thiab khub shielding / tag nrho cov shielding, uniform tis, nrog siab mechanical zog thiab rwb thaiv tsev adhesion, nrog rau zoo heev attenuation kev ua tau zoo, tsis tshua muaj latency thiab tiv thaiv kev cuam tshuam. Cov qauv ntawm cov kab sib txuas tau muab faib ua plaub txheej txheej.
² Thawj txheej, cov tub ntxhais qhwv, feem ntau yog tsim los ntawm lub tshuab wrapping los muab ob lub insulated cores thiab hauv av xaim ua ke, nrog ib txheej ntawm aluminium ntawv ci thiab ib txheej ntawm nws tus kheej nplaum polyester daim kab xev qhwv sab nraum.
² Qhov thib ob txheej, lub cable-forming cores yog tsim los ntawm ntau yam qhwv cores, dua nrog ib txheej ntawm polyester daim kab xev thiab txhuas ntawv ci mylar daim kab xev qhwv ib ncig ntawm lub txheej txheej.
² Qhov thib peb txheej, cov hlau thaiv mesh, yog cov hlau thaiv sab nraud ntawm cov tub ntxhais cable, uas yog siv los txhim kho cov nyhuv shielding ntawm cov hlau thiab tau txais kev ua haujlwm zoo dua.
² Plaub txheej, txheej txheej, yog ua los ntawm polyethylene thiab lwm yam ntaub ntawv.
DAC high-speed cable xaus ntawm cov cuab yeej kho qhov muag zoo li zoo ib yam li cov khoom siv kho qhov muag dav dav, tab sis qhov tseeb, nws tsis yog qhov kho qhov muag tiag tiag, vim tias nws tsis muaj qhov kho qhov muag laser thiab tsis muaj cov khoom siv hluav taws xob, tuaj yeem tsuas xa hluav taws xob teeb liab, tsis tuaj yeem xa cov teeb liab kho qhov muag. Vim li no, DAC high-speed cable yog pheej yig dua li optical modules, uas tuaj yeem txuag tau cov nqi thiab kev siv hluav taws xob ntau hauv cov ntawv thov luv luv, ua rau cov nqi qis, kev sib txuas lus zoo.
Tsis tas li ntawd, DAC high-speed cable muab faib ua active DAC high-speed cable thiab passive DAC high-speed cable, qhov sib txawv ntawm ob yog tias cov active DAC high-speed cable muaj ib tug ntxiv tsav nti, thaum lub active optical cable. tsis tas yuav muaj kev txawj siv hluav taws xob los tso saib nws cov yam ntxwv, thaum lub active optical cable xav tau ib qho hluav taws xob sab nraud los tso saib cov yam ntxwv. Feem ntau, thaum kis tau tus mob ntau tshaj 5 meters, thiaj li yuav txo tau qhov teeb meem ntawm teeb liab cuam tshuam, xaiv active DAC high-speed cable yog qhov tsim nyog tshaj.
DAC High Speed Cables hauv Data Center Applications
