Ntim qhov sib txawv ntawm QSFP56 thiab lwm yam QSFP series

Nyob rau hauv lub niaj hnub tsim teb ntawm network technology, qhov loj ntawm sab nraud qhov ntev ntawm optical modules plays lub luag hauj lwm tseem ceeb hauv kev txiav txim siab efficiency thiab kev ua tau zoo ntawm cov ntaub ntawv kis tau tus mob cov cuab yeej. QSFP56 yog ib qho kev nce qib tseem ceeb hauv daim teb no, dhau ntawm cov khoom lag luam yav dhau los raws li kev daws teeb meem tom ntej. Kab lus no txheeb xyuas qhov sib txawv me me hauv ntim ntawm QSFP56 thiab QSFP series rau koj siv

1, Ntim ntawm 200G QSFP56 optical module

Txhawm rau kom paub meej txog kev ntim khoom ntawm QSFP56, cia peb saib thawj lub ntim ntawm QSFP. QSFP, tseem hu ua Quad Small Form Factor Pluggable, yog plaub channel compact thiab pluggable upgrade rau SFP optical modules, hloov ib channel SFP kev daws teeb meem nrog high-density multi-channel kev daws teeb meem. QSFP feem ntau sib txuas plaub lub wavelengths rau hauv QSFP ntim cov khoom siv kho qhov muag, muab plaub npaug ntawm lub peev xwm bandwidth piv rau SFP

40G QSFP + yog kev hloov kho raws li QSFP, thiab tom qab 100G QSFP28 yog cov kev daws teeb meem siab raws li QSFP kev daws teeb meem. Nrog kev txhim kho txuas ntxiv ntawm cov ntaub ntawv tsheb khiav hauv cov chaw khaws ntaub ntawv thiab kev siv network siab heev, kev ua lag luam xav tau kev xaiv sai dua. Cov tom ntej 200G QSFP56 thiab 400G QSFP56-DD yog kev hloov kho dua tshiab thiab rov ua dua ntawm QSFP series.

Raws li kev hloov kho tshiab ntawm nws cov thawj coj 40G QSFP + thiab 100G QSFP28, plaub channel 50G daim ntawv me me pluggable QSFP56 yog tsim tshwj xeeb rau 200G Ethernet daim ntawv thov. Hauv QSFP56, 56 sawv cev rau ib qho channel tus nqi ntawm 56G, uas txhais tau hais tias 4 channels yog 4 * 56. Rau kev yooj yim, peb sib sau ua ke hu ua 200G QSFP56. Qhov loj thiab zoo li ntawm QSFP56 optical module zoo ib yam li cov QSFP module. QSFP56 optical modules raug cais raws li kev sib kis deb, suav nrog QSFP56 CR, SR, DR, FR, LR, thiab lwm yam. Txhua hom siv ntau hom lossis ib hom optical fibers rau kev sib kis nyob ntawm qhov deb.

Ob QSFP56 200G optical modules ua ke nrog ib hom lossis multimode fiber ntau tuaj yeem tsim qhov txuas 200G kis tau tus mob. Xwb, 200G QSFP56 AOC thiab DAC tuaj yeem siv rau stacking. 200G QSFP56 tuaj yeem muab faib ua ob 100G QSFP28 ceg kho qhov muag cables; 200G QSFP56 tseem tuaj yeem muab faib ua plaub 50G SFP56 ceg fibers kom yooj yim aggregation ntawm cov tub ntxhais txuas txuas.

2, Cov yam ntxwv tseem ceeb ntawm QSFP56, QSFP28, thiab QSFP +

Los ntawm lawv cov npe kev lag luam, QSFP56, QSFP28, thiab QSFP + zoo sib xws vim tias lawv muaj tib QSFP cov txheej txheem ntim khoom thiab lawv muaj qhov loj tib yam li ib leeg. Txawm li cas los xij, lawv cov chaw khaws ntaub ntawv thiab kev sib txuas muaj peev xwm sib txawv. Cov lus hauv qab no teev cov yam ntxwv ntawm QSFP56, QSFP28, thiab QSFP+.

Nrog rau kev tshaj tawm ntawm 400G QSFP-DD, uas yog plaub channel compact thiab pluggable high-density ntaus ntawv, lub neej yav tom ntej network toj roob hauv pes yuav hloov pauv tseem ceeb. Kev nce qib ntawm cov thev naus laus zis no sawv cev rau qhov kev nce qib tseem ceeb hauv kev xa cov ntaub ntawv, nrog kev nrawm li 400G ib ob. Nrog rau kev loj hlob sai ntawm cov chaw zov me nyuam, qhov kev thov rau cov ntaub ntawv ntim txuas ntxiv mus ntxiv, tsav tsheb cov khoom sib txuas kom txhawb nqa ntau dua bandwidth thiab ntom. Qhov tseeb version ntawm optical module ntim yog los ntawm QSFP56 rau QSFP56-DD, tseem hu ua 400G QSFP-DD. DD ntawm no yog hais txog ob qhov ceev, uas txhais tau hais tias los ntawm ob npaug ntawm cov ntaub ntawv raws QSFP56 los ntawm 4 raws mus rau 8 raws, nws nce mus txog 400G (siv 50G PAM4). Txawm hais tias QSFP56-DD muaj ob qhov ceev, nws qhov loj me zoo ib yam li QSFP56.

QSFP56-DD chaw nres nkoj yog rov qab siv tau nrog QSFP optical modules, uas txhais tau hais tias ntev npaum li qhov hloov pauv txhawb nws, QSFP56 tuaj yeem ua haujlwm ntawm QSFP56-DD chaw nres nkoj. Thaum siv QSFP56 module hauv QSFP56-DD chaw nres nkoj, qhov chaw nres nkoj no yuav raug teeb tsa nrog cov ntaub ntawv tus nqi ntawm 200G hloov 400G. QSFP56-DD sab nraud qhov ntev tam sim no tau lees paub los ntawm 400G kev ua lag luam raws li qhov nrov tshaj plaws 400G sab nraud qhov ntev. Txawm hais tias 400G Ethernet tam sim no pom tias yog qhov kev daws teeb meem yav tom ntej rau cov chaw khaws ntaub ntawv txuas ntxiv mus, rau qee lub koom haum siv 200G Ethernet, 200G QSFP56 tseem xav tau.
