Thaum Openai lub ZPT - 6 tus qauv sau cov ntaub ntawv sib tham tau ntau tshaj li 100 teev tsaus ntuj nti 37% congestion nyob rau hauv cov haujlwm ua haujlwm. Qhov kev lag luam hauv kev lag luam no thaum ntxov 2025 cim Ethernet tus nom kev thawj coj ntawm "lwm cov thev naus laus zis" rau ib qho "yuav tsum {12} muaj cov qauv". Raws li kev tshawb fawb tshaj tawm los ntawm kev tshawb fawb cinno, cov chaw ua haujlwm thoob ntiaj teb ntawm 60%, nrog rau cov neeg AG
Dab tsi yog 800g ethernet?
800g ethernet yog lub siab - Kev sib txuas lus ceev ntawm kev sib txuas lus ntawm kev sib txuas lus niaj hnub, nrog cov ntaub ntawv sib txuas lus ntawm kev xav tsis thoob 800 gigabits ib ob (800gps). Qhov kev nrawm no yog ob zaug ntawm cov tiam dhau los 400g eternet, muab kev txhawb zog rau cov ntaub ntawv, kev pabcuam huab thiab high} bandwidth ntawv thov.
Nws khiav ntawm 8 channel, nrog txhua channel kis ntawm tus nqi ntawm 100gbps lub channel ntawm tiam dhau los PAM4 lub teeb liab. Qhov kev kub siab no - ceev kev hloov pauv tau 800g etabet kom ua tiav cov chaw nruab nrab loj thiab kev sib txuas lus huab, ua cov ntaub ntawv sib txuas lus nrawm dua thiab ua tau zoo dua.
Kev siv ntawm 800g ethernet relies ntawm Advanced Network kho vajtse thiab kuj tau txais qis cov ntaub ntawv sib kis, tab sis kuj tau txais qis qis heev ntawm- fais fab tsim los txhim kho kev txuag hluav taws xob. Lub koom haum ntawm hluav taws xob thiab hluav taws xob engineers (IEEE) yog lub luag haujlwm rau qhov qauv ntawm 800g ethernet kom ntseeg tau tias cov khoom siv sib txawv ntawm cov khoom siv sib txawv. Qhov txheej txheem txheem txheem no yog qhov tseem ceeb rau kev ua kom muaj kev sib koom ua ke thiab ua haujlwm thoob ntiaj teb. Tus txheej txheem ua rau 800g ethernet kom paub nws lub peev xwm ntau tshaj hauv cov ntawv thov sib txawv.
Kev tsim kho kev tsim kho: Kev kawm tsim kho tshiab los ntawm txheej txheej cev kom muaj kev sib tw
Lub caij nyoog thev naus laus zis ntawm 800G ethernet tsis yog qhov kev sib txawv yooj yim tab sis ib txheej txheej txheem ntawm lub cev nqaij daim tawv, txheej ntim khoom, thiab txheej txheej. Ntawm lub cev txheej,56g Seres Pam4Kev siv thev naus laus zis tau saws, uas nce rau ib qho {{0} charnel-channel tus nqi rau 56gbps los ntawm plaub}} sam mulision tshuab. Ua ke nrog lubTxhim kho kom zoo rau pem hauv ntej kho (e - fec)Algorithm, tus nqi yuam kev me ntsis yog tswj hwm qis dua 10km, ua tiav ib qho kev txhim kho ntawm kev ntseeg tau piv rau 400g thev naus laus zis.
Kev tsim kho hauv kev tsim cov thev naus laus zis yog qhov tseem ceeb heev: Kev tsim kho hluav taws xob rau hauv 282GBs lub cim qhia kev sib kis hauv ib channel. Piv nrog cov ib txwm qsfp56 pob, nws ua tiav a200% nce rau hauv chaw nres nkoj ntomthiab kev txo 35% hauv kev noj hluav taws xob hauv tib qhov chaw txee. Ntawm qib chip, broadcom's Tomahaw siv ib qho kev siv hlau 5nm, kev txhawb nqa hlau} pa ports {}}} Latency latency nyob rau hauv 3s.
Cov Qauv Muaj: kev sib tw, kev koom tes thiab tawg hauv cov saw ntiaj teb
Tam sim no 8} Txoj Kev Lag Luam Loj}} Cov khoom lag luam loj heev Ecekhia} Qhov thib ob ecelon suav nrog cov tuam txhab neeg ua haujlwm xws li Siflower Kev Sib Txuas Lus thiab ZTE / 12.8T chips, nrog ib qho kev lag luam hauv tsev ntawm 3224; Qhov thib peb ecelon yog los nthuav dav pib tsom mus rau kev hloov kho hauv cov chaw tshiab xws li kho qhov muag thiab phy chips.
Raws li ib tug tseem ceeb tivthaiv, kho qhov muag pom muaj cov qauv sib tw los ntawm cov tuam ntxhab Suav. Tuam txhab uas cov tuam txhab xws li Zhongji snolight thiab tshiab H3C thev naus laus zis nyob ntau dua 60% ntawm lub ntiaj teb 8 /G optical module lag luam. Ntawm lawv, 800g Dr8 optical module siv silicon photonics technology, txhawb nqa kev siv hluav taws xob ntau dua, txhawb tus nqi kev txhim kho kom zoo dua ntawm cov chaw hauv cov ntaub ntawv.
