Passive cables, xws li DACs, muaj cov khoom siv hluav taws xob tsawg heev, siv hluav taws xob tsawg heev, thiab muaj txiaj ntsig zoo. Tsis tas li ntawd, nws qhov qis latency yog qhov tseem ceeb dua vim tias peb feem ntau ua haujlwm hauv lub sijhawm tiag tiag thiab xav tau kev nkag mus rau cov ntaub ntawv hauv lub sijhawm. Txawm li cas los xij, thaum siv ntev ntev nrog 112Gbps PAM-4 (hom mem tes amplitude modulation thev naus laus zis) nyob rau hauv 800Gbps / chaw nres nkoj ib puag ncig, cov ntaub ntawv poob tshwm sim dhau cov kab hluav taws xob tsis zoo, ua rau nws tsis tuaj yeem ua tiav ib txwm 56Gbps PAM-4 nrug deb tshaj 2 meters.
AEC daws qhov teeb meem ntawm cov ntaub ntawv poob nrog ntau tus retimers - ib qho thaum pib thiab ib qho thaum kawg. Cov ntaub ntawv teeb liab hla dhau AEC thaum lawv nkag mus thiab tawm, thiab cov neeg teem sijhawm kho dua cov ntaub ntawv teeb liab. AEC's retimers ua kom pom tseeb dua, tshem tawm cov suab nrov, thiab ua kom cov paib kom pom tseeb, pom tseeb dua cov ntaub ntawv xa mus.
Lwm hom kab hluav taws xob uas muaj cov khoom siv hluav taws xob muaj zog yog tooj liab (ACC), uas muab lub tshuab hluav taws xob tawm tsis siv lub retimer. Retimers tuaj yeem tshem tawm lossis txo cov suab nrov hauv cables, tab sis linear amplifiers tsis tuaj yeem. Qhov no txhais tau hais tias nws tsis hloov lub teeb liab, tab sis tsuas yog amplifies lub teeb liab, uas kuj amplifies lub suab nrov. Qhov kawg tshwm sim yog dab tsi? Obviously linear amplifiers muab kev xaiv tus nqi qis, tab sis retimers muab lub teeb liab pom tseeb. Muaj qhov zoo thiab qhov tsis zoo rau ob qho tib si, thiab qhov twg los xaiv yog nyob ntawm daim ntawv thov, kev ua haujlwm xav tau, thiab nyiaj txiag.
Hauv cov xwm txheej plug-and-play, retimers muaj qhov ua tau zoo dua. Piv txwv li, cables nrog linear amplifiers tuaj yeem tawm tsam kom tswj tau qhov kev ua tau zoo ntawm lub teeb liab kev ua tau zoo thaum sab saum toj-ntawm-rack (TOR) keyboards thiab servers txuas nrog lawv yog tsim los ntawm cov neeg muag khoom sib txawv. Cov neeg saib xyuas cov ntaub ntawv tsis zoo li yuav xav tau txhua yam khoom siv los ntawm tib tus neeg muag khoom, lossis hloov cov khoom siv uas twb muaj lawm los tsim ib qho kev daws teeb meem los ntawm sab saum toj mus rau hauv qab. Hloov chaw, feem ntau cov ntaub ntawv chaw sib xyaw thiab sib tw cov cuab yeej los ntawm cov neeg muag khoom sib txawv. Yog li ntawd, kev siv cov retimers feem ntau yuav ua tiav "plug thiab ua si" ntawm cov servers tshiab hauv cov txheej txheem uas twb muaj lawm nrog cov channel tau lees paub. Hauv qhov no, retimeing kuj txhais tau tias kev txuag nqi tseem ceeb.
