Yuav Ua Li Cas Hloov Chaw Nres Los Ntawm QSFP + rau SFP + Chaw nres nkoj?
Yuav Ua Li Cas Hloov Chaw Nres Los Ntawm QSFP + rau SFP + Chaw nres nkoj?
Nrog kev tuaj txog ntawm 40G Ethernet, ntau tus neeg siv khoom lag luam yuav tsum xav txog yuav ua li cas hloov lawv lub network mus rau 40G network nrog kev siv tag nrho ntawm 10G network infrastructure tam sim no. Tshwj xeeb, thaum tshiab 40G hloov tshiab nrog QSFP + cov chaw nres nkoj tau ntxiv rau hauv, yuav ua li cas txuas ncaj qha nrog koj cov khoom siv 10GbE uas twb muaj lawm (xws li cov keyboards thiab servers) nrog SFP + cov chaw nres nkoj yog qhov tseem ceeb tshaj plaws uas koj yuav tsum xav txog. Hauv cov ntawv tshaj tawm no, peb txoj kev siv kev tsiv teb tsaws chaw ncaj qha los hloov chaw nres nkoj los ntawm QSFP + rau SFP + yuav muab qhia rau koj siv.
1️⃣ QSFP + rau SFP +: QSFP + Breakout Cable
Thawj txoj hauv kev ncaj qha hloov QSFP + rau SFP + chaw nres nkoj yog siv QSFP + breakout cable. QSFP + breakout cables tam sim no tuaj yeem pom nyob rau hauv direct txuas cable (DAC) thiab active optical cable (AOC) hom. Feem ntau, ob hom yog ua ntej txiav nrog QSFP + transceiver ntawm ib kawg thiab plaub SFP + transceivers ntawm lwm kawg, uas yog hu ua QSFP + rau SFP + breakout cables. Qhov txawv ntawm qhov DAC yog tsim nrog tooj liab cables thaum AOC siv fiber ntau optics.
Tsis tas li ntawd, muaj lwm hom 40G AOC breakout cable - QSFP + rau 4 duplex LC cable. Nws muaj QSFP + transceiver ua ntej txiav tawm ntawm ib kawg tab sis LC duplex connectors ntawm lwm kawg, uas yuav tsum tau ntxiv SFP + transceivers thaum siv.
Txawm hais tias koj xaiv hom twg, tag nrho cov QSFP + breakout cables tuaj yeem faib 40G kev sib txuas rau hauv 4x10G raws, thaum koj txuas lawv nrog QSFP + hloov ntawm ib kawg thiab ob peb 10G khoom siv (txog plaub) uas muaj SFP + chaw nres nkoj ntawm lwm qhov kawg.
2️⃣ QSFP + rau SFP +: MTP / MPO-LC Breakout Cable

Qhov thib ob txoj kev los hloov QSFP + rau SFP + chaw nres nkoj yog siv MTP / MPO rau LC breakout cable. Qhov kev daws teeb meem no zoo ib yam li cov tshuaj ua ntej tab sis tsis muaj qhov transceiver ua ntej txiav tawm ntawm txhua qhov kawg. Nrog rau MTP / MPO connector ntawm ib sab, MPO / MTP 8- fiber ntau sib dhos yog feem ntau nruab nrog plaub LC duplex connectors ntawm sab nraud. Txhawm rau kom paub qhov hloov dua siab tshiab los ntawm 40G rau 10G siv MTP / MPO rau LC breakout cable, koj yuav tsum ntxiv ib QSFP + transceiver nrog MTP / MPO interface thiab plaub SFP + modules nrog duplex LC interfaces. Raws li daim duab qhia hauv qab no, koj tsuas yog yuav tsum ntsaws cov cables rau hauv qhov sib txuam 10G lossis 40G transceivers thiab tom qab ntawd ntxig cov transceivers rau hauv QSFP + chaw nres nkoj lossis SFP + chaw nres nkoj.
3️⃣ QSFP+ to SFP+: QSFP-SFP10G-CVR (QSA)
Lwm txoj hauv kev ncaj qha hloov QSFP + rau SFP + chaw nres nkoj yog los ntawm kev pab los ntawm 10G hom QSA (quad me me-factor pluggable adapter): QSFP-SFP10G-CVR. Ua-hauv QSFP + daim ntawv foos nrog lub tawb rau SFP + module nyob tom qab, qhov QSFP + rau SFP + adapter no ua rau kev sib txuas zoo ntawm cov khoom siv uas siv 40G QSFP + chaw nres nkoj thiab 10G SFP + chaw nres nkoj. Txhawm rau kom muaj kev sib txuas 10G, koj tuaj yeem ntxig SFP + module rau hauv QSFP + rau SFP + adapter thiab tom qab ntawd txuas QSFP-SFP10G-CVR adapter rau QSFP + chaw nres nkoj. Hauv kev sib txuas ntawd, QSFP + rau SFP + adapter yuav ua raws li kev sib txuas ntawm SFP + module.
