QSFP56 pob khoom yog dab tsi?

Ua ntej tshaj, cia peb saib ntawm cov qauv tsim ntawm QSFP pob. Lub Plaub Hlis Qib Me Daim Ntawv Txheej Txheem Me Muaj Peev Txheej Txheem Pluggable yog hais txog plaub-channel cov ntawv me me-qhov ua tau zoo pluggable SFP interface (QSFP). Channel SFP optical module. Piv nrog SFP optical modules, QSFP optical modules muaj bandwidth ntau dua.

40G QSFP + thiab 100G QSFP28 kho qhov muag tau tsim raws cov QSFP ntim tau pib maj mam pib siv rau cov chaw siab ceev cov ntaub ntawv. Nrog cov kev loj hlob tsis tu ncua ntawm cov ntaub ntawv chaw tsheb thiab cov bandwidth siab dua, QSFP pob hom muaj tseem tau tshwm sim nrog ntau daim ntawv foos, xws li 200G QSFP56 thiab 400G QSFP56-DD ob hom pob no.

QSFP56 optical module tau hloov kho dua tshiab ntawm 40G QSFP + thiab 100G QSFP28 optical modules. Nws yog qhov kho qhov muag hluav taws xob tau tsim tshwj xeeb rau 200G Ethernet kev sib tshuam. QSFP56 qhia tau hais tias qhov kis tau tus mob ntawm 4x 50Gb / s txog 56Gb / s tuaj yeem sib kis tau hauv QSFP pob loj. Qee zaum, kom yooj yim, QSFP56 optical module kuj tseem hu ua 200G QSFP optical module. Raws li kev sib kis sib txawv, QSFP56 optical module tuaj yeem muab faib ua QSFP56 CR, SR, DR, FR, LR cov hom, uas tuaj yeem ua tiav qhov sib txawv ntawm cov kis ntawm ib hom thiab ntau hom fiber ntau.

Feem ntau, ntxig ob lub QSFP56 kho qhov muag coj mus rau qhov chaw nres nkoj coj mus txuas rau thiab txuas lawv nrog tib-hom lossis ntau hom kho qhov muag kom ua tiav qhov sib kis tau ntawm 200G. Ntxiv rau, ntsaws QSFP56 DAC / AOC txoj kev kub ceev hluav taws xob rau hauv chaw nres nkoj coj los ua kom tiav 200G kev xa khoom. Yog tias koj xav kom ua tiav qhov kis tau tus mob ntawm 2x100G lossis 4x50G, koj tuaj yeem siv 200G QSFP56 txog 2x100G QSFP28 ceg hluav taws xob thiab 200G QSFP56 txog 4x50G SFP56 ceg txuas hluav taws xob.

200G QSFP56 thiab 200G QSFP-DD yog ob lub ntsiab kev daws teeb meem rau 200G kev sib txuas lus kho qhov muag. QSFP56 siv cov ntsiab lus siv hluav taws xob digital digital processors (DSP) los pab huab chaw cov ntaub ntawv huab hwm txog cov kev cov nyom loj thiab ua tiav cov kev nthuav dav nrawm nrog cov nplai hloov tau yooj yim thiab cov nqi. Kev kho qhov muag sib txuas. Kab ntawv no tsuas yog yuav qhia koj txog 200G QSFP56 ntim thev naus laus zis thiab qhov sib txawv ntawm lwm QSFP + ntim.

QSFP56 vs QSFP28 vs QSFP +

Los ntawm kev pom lub npe, cov pob hom QSFP56, QSFP28 thiab QSFP + optical module tau zoo ib yam, tab sis lawv cov kev sib hloov xa mus, kev siv tshuab, interface, thiab lwm yam. Cov ntaub ntawv hauv qab no teev cov kev tsis yooj yim ntawm cov hom pob no:

Raws li tuaj yeem pom los ntawm cov lus saum toj no, QSFP56 pob hom optical module tuaj yeem pab txhawb 4x50G kis mus rau kis tau ntawm 200G. QSFP + optical module yog ib qho kho dua tshiab ntawm QSFP optical module, tuaj yeem txhawb 4x10G kev xa khoom kom paub txog qhov kis ntawm 10G Ethernet, 10G Fiber Channel thiab QDR InfiniBand. Nws tuaj yeem multiplex plaub kis kom nce bandwidth thiab ua tiav cov kis tau los ntawm 40Gbps (10GBaud NRZ ib channel). QSFP28 optical module, zoo li QSFP + optical module, suav nrog 4 lub tshuab xa hluav taws xob thiab 4 lub kho qhov muag, txhawb 4x25G kis, thiab ua tiav cov kis tau ntawm 100G.

Qhov loj tshaj qhov sib txawv ntawm QSFP56 pob thiab QSFP +, QSFP28 pob yog tias QSFP56 tsis siv cov NRZ kev hloov kho tshuab dhau los, tab sis siv PAM4 kev siv thev naus laus zis. Kev sib kis ntawm txhua tus channel tuaj yeem ncav cuag 50G, thiab nws tseem tuaj yeem xa ntau ntxiv ntawm cov kab hluav taws xob uas twb muaj lawm. Cov ntaub ntawv ntau dua zoo dua rau kev siv hauv ultra-large-scale data center network.

Kev hloov ntawm QSFP56 rau QSFP56-DD (400G QSFP-DD) pob

Nrog txoj kev loj hlob sai ntawm cov chaw zov me nyuam cov ntaub ntawv, qhov kev thov rau cov ntaub ntawv sib kis tau nce siab tas li, uas txhawb txoj kev loj hlob ntawm cov tes hauj lwm kom tau ntau dua cov kab thiab qhov ntau dua. Tam sim no, lub cim tshiab ntawm 400G optical module ntim hom tau tshwm sim nyob rau hauv kev ua lag luam-400G QSFP-DD, qhov twg" DD" hais txog qhov muab qhov ntuag ob npaug, uas txhais tau hais tias cov naj npawb ntawm cov channel ntawm 400G QSFP-DD tau hloov ntawm 4 mus rau 8, tuaj yeem ncav cuag qhov kis tus nqi ntawm 400G.

Qhov loj ntawm QSFP56-DD zoo ib yam li QSFP56, tab sis nws tuaj yeem thim rov qab tau nrog QSFP ntim cov kho qhov muag, xws li QSFP +, QSFP28, QSFP56, thiab lwm yam hauv, txhais tau tias ntev li tus hloov hloov tau txhawb nqa nws , QSFP56 tuaj yeem ua haujlwm ntawm QSFP56-DD cov chaw nres nkoj. Thaum QSFP56 optical module siv rau QSFP56-DD, qhov chaw nres nkoj ntawm lub pob hluav taws xob yuav teeb tsa nrog qhov hloov tus nqi ntawm 200G hloov mus txog 400G.

Txawm hais tias QSFP56-DD pob tam sim no pob khoom nrov tshaj plaws rau 400G Ethernet, qhov no tsis txhais tau tias QSFP56 pob hom yog raug tshem tawm. Rau qee cov chaw zov me nyuam cov ntaub ntawv thiab cov koom tes lag luam uas xa 200G Ethernet, 200G QSFP56 pob hom optical Modules tseem yog qhov kev daws teeb meem zoo tshaj plaws.
