Rau luv-diHigh-kev ua tau zoo thiab tsis raug nqi yog qhov kev xaiv thawj rau cov neeg siv network xa mus.stance 40G kev xaib network, QSFP + DAC high-speed cable thiab QSFP + AOC optical optical cable muaj tus nqi qis thiab cov hauj lwm siab, thiab tau siv dav hauv kev lag luam network thiab cov chaw xa khoom, xws li kev sib txuas ntawm cov hloov thiab cov neeg rau zaub mov. Koj puas paub txog ob hom cable no zoo li cas? Qhov sib txawv ntawm QSFP + DAC txoj kev kub ceev cable thiab AOC active cable yog dab tsi? Dab tsi' s qhov sib txawv ntawm ob hom cable no thiab QSFP + optical module txuas nrog optical fiber?
QSFP + DAC txoj kev kub ceev cable yog dab tsi?
40G QSFP + DAC high-speed cable yog kab hluav taws xob high biaxial cable nrog QSFP + cov txuas ntawm ob tog. Cov xov mas siv cov nyiaj plated neeg xyuas pib, insulating tub ntxhais hlau ntawm lub cev foaming polyolefin khoom, thiab cov xov hlau thaiv cov ntaub thaiv los yog tag nrho cov ntaub thaiv npog. Feem ntau, cov xov hlau qhov ntsuas ntawm cov xaim hluav taws xob (tooj liab txoj kab hluav taws xob kav) yog nruab nrab ntawm 24 thiab 30awg. Qhov loj dua ntawm cov hlau ntsuas qhov ntsuas yog, qhov siab dua qib ntawm xaim los ntawm lub qhov yog, qhov taub loj ntawm lub xaim yog. Yog li, ntev dua DAC txoj kab hluav taws xob txuas tau ntev npaum li cas, cov hlau ntsuas qhov ntsuas me dua. Qhov no tuaj yeem txo qhov poob ntawm cov teeb liab xa mus, uas yog, qhov tsawg dua cov xov tooj hlau qhov tsawg dua, qhov kev sib kis tau ntev npaum li cas.
QSFP + DAC hom
QSFP + DAC txoj kev kub ceev hluav taws xob tau muab faib ua ob hom: nquag thiab passive. Lub passive QSFP + DAC txoj kev kub ceev cable tsis muaj lub npav tsav, yog li nws tuaj yeem xa cov teeb liab tsis muaj lub zog hluav taws xob tsav, thiab cov teeb liab yuav tsis nthuav dav lossis sib luag hauv cov txheej txheem kev sib kis. Feem ntau hais lus, qhov siab tshaj qhov kis tau ntawm passive QSFP + DAC high-speed cable yog 7 meters, thaum lub zog QSFP + DAC high-speed cable muaj tsav nti rau lub teeb liab, yog li nws kis tau nrug yog me ntsis ntev dua, ntev li 10 metres lossis ntev dua.
Daim Ntawv Thov ntawm QSFP + DAC
Tam sim no, QSFP + DAC high-speed cables rau ntawm kev ua lag luam suav nrog 40G QSFP + rau QSFP + DAC high-speed cables thiab 40G QSFP + rau 4 * SFP {{ 9}} tus xov tooj cua nrawm. Cov ntawv thov siv ntawm ob hom ntawm QSFP + DAC txoj kev kub ceev sib txawv. Ntawm lawv, QSFP + rau QSFP + DAC cov kab hluav taws xob loj yog siv rau cov luv 40G sib txuas ncaj qha sib txuas, xws li 40G hloov thiab 40G network daim npav txuas ncaj qha; thaum QSFP + txog 4 * SFP + ceg DAC cov xov tooj hluav taws xob nrawm muaj peev xwm cais tau 40G teeb liab rau plaub 10G cov lus qhia, yog li nws yog siv rau 10G-40G network kev txhim kho.
QSFP + AOC active optical cable yog dab tsi?
QSFP + AOC active optical cable yog tsim ntawm optical fiber thiab ob QSFP + cov khoom txuas (ib qho kawg ntawm ib qho). Cov khoom siv fiber ntau ntawm QSFP + AOC nquag optical cable yog multimode optical fiber, thiab QSFP + kev txuas ntawm QSFP + AOC nquag kho qhov muag cable yog qhov tseeb QSFP + optical module. Yog li ntawd, cov qauv thiab nqe ntawm QSFP + AOC active optical cable yog ntau txoj thiab kim dua li ntawm QSFP + DAC high-speed cable. QSFP + AOC active optical cable xav tau hluav taws xob sab nraud kom paub qhov kev hloov ntawm hluav taws xob teeb liab thiab teeb liab kho qhov muag, thiab qhov siab tshaj plaws kis tau mus txog 100 meters.
QSFP + AOC hom
Tam sim no, kev lag luam tau tsim ntau yam QSFP + AOC nquag kho qhov muag hluav taws xob rau cov sib txawv ntawm 40G kis tau cov ntawv thov, suav nrog peb hom (qhov tseem ceeb) ntawm 40G QSFP + AOC nquag optical cable, 40G QSFP {{5} } rau 4 * SFP + nquag ceg optical cable thiab 40G QSFP + rau 8 * LC nquag ceg optical cable (namely 40G QSFP + txog 4 * duplex LC nquag ceg optical cable). Ntxiv rau, qee tus neeg xa khoom tuaj yeem tuaj yeem muab kev pabcuam customized ntawm 40G QSFP + rau 8 * SC / ST / FC active ceg optical cable.
Daim Ntawv Thov ntawm QSFP + AOC
QSFP + AOC nquag kho qhov muag cable yog qhov kev siv nyiaj, uas tuaj yeem siv rau qhov kev sib txuas ntawm ob lub viav vias 40G. 40G QSFP + cov ceg ntoo txuas cable kho mob haum rau 10G-40G kev txhim kho network. Nws yuav tsum raug sau tseg tias 40G QSFP + txog rau 8 * LC active ceg optical cable siv yuav tsum muaj 10 10G SFP + optical modules los txuas LC duplex cov khoom sib txuas.
Qhov txawv ntawm QSFP + DAC thiab QSFP + AOC yog dab tsi?
Txoj ntsiab cai ua haujlwm
Vim tias cov qauv sib txawv ntawm QSFP + DAC thiab QSFP + AOC, lawv cov haujlwm ua haujlwm sib txawv. Ob lub siab thiab nquag QSFP + DAC tuaj yeem siv tooj liab cable rau teeb liab kis. Lub siab dhau QSFP + DAC tuaj yeem xa ncaj qha tsis muaj kev ntsuas lub teeb tsa, thiab nquag QSFP + DAC tuaj yeem ua kom nrov dua thiab tom qab ntawd xa cov teeb liab los ntawm cov tsav tsheb sib dhos. Lub teeb liab kis ntawm QSFP + AOC ua tiav los ntawm optical fiber, thiab nws muaj peev xwm tsuas paub txog kev hloov ntawm hluav taws xob teeb liab mus rau lub teeb liab kho qhov muag thiab tom qab ntawd mus rau lub teeb liab hluav taws xob nrog kev pab los ntawm lub zog hluav taws xob.
Kev hloov mus deb
Nws tuaj yeem pom los ntawm cov saum toj no uas QSFP + AOC active optical cable transmits cov teeb liab los ntawm optical fiber, thaum QSFP + DAC high-speed cable xa cov teeb liab los ntawm tooj liab cable. Yog li, kev xa cov peev xwm ntawm QSFP + AOC active optical cable yog qhov muaj zog dua li ntawm QSFP + DAC high-speed cable, thiab qhov siab tshaj plaws kis tau deb yog li 100 meters. Nyob rau tib lub sijhawm, QSFP + AOC muaj cov xov hluav taws xob me me uas siv hluav taws xob me me thiab ntau txoj hauv kev.
Nqi
Hauv kev hais txog tus qauv, QSFP + DAC muaj cov qauv yooj yim thiab ob peb lub ntsej muag, thiab nws cov nqi feem ntau yog qis dua QSFP + AOC.
HTF' s cov khoom lag luam zoo tau lees tias, thiab cov khoom siv siv tau yog txawv txawv.
