Common DAC high-speed cable faib

DAC high-ceev cable(Direct Attach Cable) feem ntau txhais tau hais tias ncaj qha cable, ncaj qha txuas tooj liab cable lossis high-speed cable.Nws txhais tau tias yog tus nqi qis-nqi luv-kev sib txuas txoj kev uas hloov kho qhov muag modules.Ob qhov kawg ntawm kev kub ceev cable muaj modules Cable sib dhos, tsis hloov chaw nres nkoj, module taub hau thiab tooj liab cables tsis tuaj yeem sib cais, tab sis piv rau optical module active optical cables (Active Optical Cables), connector modules ntawm high-speed cables ua. tsis muaj kim kho qhov muag lasers thiab lwm yam khoom siv hluav taws xob, yog li Qhov tseem ceeb ntawm kev txuag nqi thiab kev siv hluav taws xob hauv kev siv luv luv.Nrog Ethernet ceev dua, huab xam, Is Taws Nem ntawm Yam, thiab cov chaw khaws ntaub ntawv virtual, ntau qhov kev xav tau tau muab tso rau hauv cov neeg ua haujlwm hauv cov ntaub ntawv.Cov ntaub ntawv ceev yog tiag tiag ntawm txoj kev mus rau 400G, yog li ntxiv rau kev sib txuas hauv 3-5m hauv cov neeg rau zaub mov, DAC kuj tuaj yeem siv tau (5-7 meters yuav tsum siv cov ntaub ntawv tshwj xeeb insulating kom tau raws li cov yam ntxwv xav tau).Kev sib txuas dhau qhov kev ncua deb no feem ntau pom tau los ntawm AOC.

10G SFP + rau SFP + Kev kub ceev Kab

Lub 10GB SFP + rau SFP + DAC siv ib lub siab tawv ntxaib thiab txuas ncaj qha rau SFP + Module, muaj zog siab, tus nqi qis, thiab qis latency.

Dab tsi ntawm 10G SFP + rau SFP + kev kub ceev cables muaj?

Feem ntau hais lus, muaj peb hom 10G SFP + rau SFP + high-speed cables:

10G SFP + passive tooj liab core high-speed cable (DAC),

10G SFP + Active Copper Core High Speed ​​​​Cable (ACC),

10G SFP + Active Optical Cable (AOC),

Lawv tsim nyog rau kev sib txuas hauv network hauv ib lub khib nyiab thiab nruab nrab ntawm cov racks uas nyob ib sab thiab muaj txiaj ntsig zoo heev.

SFP + passive tooj liab core high-speed cable muab cov hluav taws xob ncaj qha cuam tshuam nruab nrab ntawm ob qhov kawg ntawm cov kab sib txuas, thiab qhov kev sib txuas ntawm qhov deb tuaj yeem ncav cuag 12m.Txawm li cas los xij, vim qhov hnyav hnyav ntawm lub cable thiab xav txog qhov teeb meem ntawm kev ncaj ncees, nws siv ntev Nws feem ntau txwv rau ntawm 7m thiab 10m.

40G QSFP + rau QSFP + Kev Kub Ceev Cable

A 40G high-speed cable (DAC) hais txog kev sib txuas nrog cov fiber ntau optic transceivers ntawm ob qho kawg, uas tuaj yeem ua tiav 40Gbps cov ntaub ntawv xa mus thiab yog tus nqi siv hluav taws xob sib txuas sib txuas.Qhov ntau tshaj 40G high-speed cables tuaj yeem muab faib ua peb hom: 40G QSFP + rau QSFP + DAC, 40GQSFP + rau 4 * SFP + DAC, thiab 40GQSFP + rau 4XFP + DAC.

40G QSFP + rau QSFP + DAC yog tsim los ntawm ob 40G QSFP + optical transceivers thiab tooj liab tub ntxhais nyob ntawm tej.Qhov kev kub ceev no tuaj yeem siv los paub txog kev sib cuam tshuam ntawm 40G QSFP + chaw nres nkoj rau 40G QSFP + chaw nres nkoj, feem ntau tsuas yog hauv 7m.nyob deb.

40G QSFP + rau 4 × SFP + DAC yog tsim los ntawm ib qho 40G QSFP + optical transceiver, tooj liab tub ntxhais hlau thiab plaub 10G SFP + optical transceivers.Ib kawg yog 40G QSFP + interface, uas ua tau raws li qhov xav tau ntawm SFF-8436, thiab lwm qhov kawg yog plaub 10G SFP + interfaces., raws li qhov yuav tsum tau muaj ntawm SFF-8432, feem ntau yog siv los paub txog kev sib tshuam ntawm 40G thiab 10G cov cuab yeej (NIC / HBA / CNA, hloov khoom siv thiab cov neeg rau zaub mov), raws li tus neeg siv khoom xav tau rau qhov ntev ntawm cov cables ntawm ob qho kawg, feem ntau tsuas yog hauv 7m.Qhov deb, tam sim no yog qhov kev lag luam tshaj plaws thiab yooj yim kom ua tiav qhov chaw nres nkoj hloov pauv.

40G QSFP + rau 4XFP DAC yog tsim los ntawm ib qho 40G QSFP + optical transceiver, tooj liab tub ntxhais hlau thiab plaub 10G XFP optical transceivers.Txij li thaum XFP fiber optic transceiver tsis muaj DAC tooj liab cable tus qauv, lub teeb liab them nyiaj muab los ntawm lub cuab yeej yog tsawg, thiab qhov poob ntawm cable nws tus kheej yog loj heev.Nws tsuas yog siv tau rau kev sib kis luv luv, feem ntau nyob hauv qhov deb ntawm 2m.Yog li ntawd, qhov no high-speed cable yuav siv tau rau Interconnects uas twb muaj lawm 40G QSFP + chaw nres nkoj rau 4 XFP chaw nres nkoj.

25G SFP28 rau SFP28 Kev kub ceev Cable

25G SFP28 rau SFP28 DAC tuaj yeem muab cov neeg siv khoom nrog 25G high-bandwidth cov ntaub ntawv sib cuam tshuam muaj peev xwm, raws li IEEE P802.3by Ethernet tus qauv thiab SFF-8402 SFP28, thiab tau siv dav hauv cov ntaub ntawv chaw lossis supercomputing centre system scenarios.
