Dab tsi yog lub cev txheej ntawm tsheb eternet? Dab tsi yog lub cev txheej ntawm tsheb eternitive ethernet?

1, cov ntsiab lus yooj yim ntawm cov txheej txheej ntawm lub tsheb ethernet
Lub cev txheej ntawm cov ethernet, nyob rau hauv luv, yog txheej txheej txheem ntawm cov ntaub ntawv sib txuas, thiab lwm yam, kis tus nqi, thiab kev sib txuas ntawm cov ntaub ntawv. Hauv kev tsheb Ethernet, tus tsim qauv ntawm lub cev txheej txheem ncaj qha cuam tshuam kev ruaj ntseg, kev ntseeg tau, thiab kev ua haujlwm ntawm lub network.
2, thev naus laus zis tseem ceeb rau lub cev txheej ntawm tsheb eternet
Kev ntsuas cov teeb liab sib txawv: Cov kauj ruam ethernet siv cov teeb liab kev sib kis tshuab los xa cov ntaub ntawv los ntawm ib lossis ntau tus khub ntawm khub khub khub cable. Kev ntsuas tus teeb liab sib txawv tuaj yeem ua kom zoo rau kev cuam tshuam hluav taws xob hauv hluav taws xob, txhim kho cov teeb meem tiv thaiv kev cuam tshuam thiab kis tau zoo.
MEME ceev lub zog (PAM): PAM yog cov txheej txheem kev hloov pauv uas kis tau cov ntaub ntawv los ntawm kev hloov pauv ntawm lub teeb liab. Hauv Automotive Ethernet, Pam Technology yog siv los sib npaug bandwidth thiab electromagnetic sib haum (EMI) kev ua tau zoo. Piv txwv li, lub 100base-T1 tus qauv siv PAM3 kev daws teeb meem thiab tuaj yeem ua tiav 666.666 MBPS tag nrho Duplex kev sib txuas lus ntawm khub uas tsis tau sib txuas lus sib txuas lus.
Lub cev encoding sublayer (pcs) thiab lub cev me me): PCS yog lub luag haujlwm ntawm cov ntaub ntawv txuas rau lossis tau txais cov ntaub ntawv sau los ntawm lub cev nruab nrab thiab dai kom nws. Ob txoj kev ua tiav ob kab ua ke tsim cov tub ntxhais ntawm lub cev txheej ntawm cov etrouse ethernet.
3, Txheem rau lub cev txheej ntawm cov eternive eternet
Cov qauv rau lub cev txheej ntawm cov etherive ethee yog tsim los ntawm cov hluav taws xob thiab cov neeg sawv cev hluav taws xob), nrog cov neeg sawv cev feem ntau yog 100base-T1 thiab 1000base-T1.
100Base-T1: Qhov no yog Ethernet tus qauv tsim tshwj xeeb rau cov khoom sib txuas lus sab hauv, nrog kev sib txuas lus zoo tshaj plaws ntawm 15 metres (li 40 metres thaum siv cov ntaub thaiv npog khub cable). Lub 100base-T1 tus qauv txhawb tag nrho chav sib txuas lus tag nrho thiab tuaj yeem muab cov ntaub ntawv kis tau ntawm nce txog 100 MBPS.
1000base-T1: Qhov no yog hloov kho tshiab ntawm 100base-T1, muab cov nqi hloov mus rau li 1 GBPS. Txawm li cas los xij, vim kev ua haujlwm nyuaj thiab raug nqi ntau, daim ntawv thov ntawm 1000base-T1 hauv automotive eternet yog tsawg.
4, cov kev sib tw thiab cov kev daws teeb meem rau lub cev txheej ntawm tsheb eternet
Electromagnetic Compatibility (EMI): Muaj ntau cov hauv hluav taws xob sib cuam tshuam hauv lub tsheb, thiab lwm yam ntawm kev cuam tshuam rau kev sib txuas lus Ethernet. Txhawm rau kom daws tau cov teeb meem no, cov txheej txheej lub cev ntawm cov tshuab ethernet adops kis thiab tiv thaiv khub sib txuam los txhim kho kev tiv thaiv kev tiv thaiv kev cuam tshuam.
Kev Sib Kis Txog Kev Txwv Tsis Pub: Vim tias cov kev txwv ntawm cov kev txwv sab hauv, nrog rau cov teeb meem hluav taws xob, kev tawm tsam ntawm lub tsheb Ethernet yog raug rau qee qhov kev txwv. Txhawm rau kom daws tau cov teeb meem no, cov khoom siv network xws li rov ua kom ntev li cov tsheb ciav hlau xws li kev siv fiber ntau ntawm cov kab mob fiber ntau ntxiv.
Tus nqi teeb meem: Tus nqi kho vajtse ntawm cov etrouse eternet yog tus kheej kuj tseem ceeb, tshwj xeeb tshaj yog rau kev ua haujlwm siab ntawm lub cev. Txhawm rau txo tus nqi, tsheb tuam ntxhab thiab cov chaw muag khoom siv zog los txhim kho cov thev naus laus zis tshiab thiab txo cov nqi khoom.
5, Kev tsim kho yav tom ntej yav tom ntej ntawm tsheb Ethernet Lub Cev Txheej Txheem
Nrog kev txhim kho kev txuas ntxiv ntawm cov thev naus laus zis xws li kev tsav tsheb automonies thiab lub tsheb sib txuas, lub cev txheej txheem ntawm cov kev sib tw hauv tsheb qib siab thiab cov cib fim. Yav tom ntej, kev txhim kho ntawm lub cev txheej txheej ntawm cov etrouse Ethernet yuav suav nrog:
Kev ua kom muaj kev tsav tsheb ntau dua: txhawm rau kom tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob nrawm dua thiab txuas ntxiv txhim kho ntawm bandwidth thiab qis dua.
Cov muaj zog tiv thaiv kev cuam tshuam muaj zog: nrog cov muaj koob meej ntawm hluav taws xob thiab cov tsheb hybrid, lub chaw siv hluav taws xob hauv tsheb yuav dhau los ua cov nyom. Yog li ntawd, lub cev txheej txheej ntawm cov ethernitive ethernet yuav xav tau cov peev xwm cuam tshuam muaj zog los daws cov kev cov nyom no.
Tus nqi qis thiab siab dua kev ntseeg tau: txhawm rau txo cov nqi tsim khoom thiab cov khoom lag luam tawm tshiab txuas ntxiv rau cov qauv tsim ntawm cov txheej txheem ntawm cov ethernitive ethernet.
