400 GBase - SR8
Txais ib lub wavelength unidirectional 8 raws ntawm ntau hom optical fiber, txhua channel xa 50G. Lub interface siv 16-core MPO lossis 24-core ob kab MPO interface. Multimode fiber ntau tuaj yeem yog OM3, OM4 thiab OM5, txhawb nqa ntev ntawm 70 meters, 100 meters, 150 meters feem. Daim ntawv thov no yog tus cwj pwm los ntawm qhov tseeb tias txhua qhov kev sib txuas yuav tsum muaj 16 cores ntawm fiber ntau los txhawb cov fiber ntau, thaum daim ntawv thov ib leeg ua rau tus nqi transceiver qis.
400 GBase - SR4.2
Nws txais yuav 4-channel parallel kis technology thiabWDM technology, thiab txhua channel xa 50G nyob rau hauv ob qho tib si qhia, tag nrho ntawm 100G. Lub interface siv tau zoo tib yam 12-core MPO, 8 cores ntawm ob sab tuaj yeem siv rau kev sib kis, ntau hom fiber ntau tuaj yeem siv OM3, OM4 thiab OM5, qhov ntev ntawm kev txhawb nqa yog 70 meters, 100 meters, 150 meters feem. . Daim ntawv thov no nta: lub interface yog tib yam li 40G / 100G thiab tuaj yeem ua rau qis dua, tab sis vim yog WDM thev naus laus zis, tus nqi ntawm transceiver yog siab dua li ntawm ib lub wavelength transceiver.
400 GBase - DR4
Ib hom fiber ntau ib leeg-yoj ib ntus kev sib txuas lus thev naus laus zis tau txais yuav, nrog rau txhua txoj kev xa tawm 100Gbps hauv ib qho kev coj. Lub interface tuaj yeem txais qhov zoo tib yam12-core single-mode MPO, thiab 8-core ntawm ob sab tuaj yeem siv rau kev xa xov, txhawb nqa daim ntawv thov nyob deb ntawm 500 meters. Daim ntawv thov nta: lub interface yog tib yam li 40G / 100G thiab tuaj yeem ua tau zoo sib xws. Muaj ib daim ntawv thov wavelength. Tus nqi ntawm transceiver muaj qhov zoo dua tus nqi ntawm ntau hom transceiver.
400 GBase - FR8
Tib hom fiber ntau 8 wavelength division multiplexing technology yog saws, thiab txhua wavelength kis mus rau 50Gbps. Lub interface tuaj yeem txais ib hom LC zoo tib yam, txhawb nqa daim ntawv thov kev ncua deb ntawm 2km. Daim ntawv thov no nta: txhawb kev mus ntev, tsuas yog ib khub ntawm ib hom fiber ntau, lub interface tuaj yeem siv tib hom LC, vim yog siv CWDM daim ntawv thov, tus nqi transceiver yog siab heev.
Cov lus xaus
Txawm hais tias tsis muaj tsawg dua 10 daim ntawv thov qauv rau 400G, los ntawm kev xav ntawm cov ntaub ntawv chaw siv, cov qauv rau cov ntawv thov tseem ceeb ntawm 400G yav tom ntej yuav tsis tshaj plaub hom saum toj no. Raws li txoj cai evolution ntawm cov pob txha ntawm cov ntaub ntawv chaw, qhov kev txhawb nqa daim ntawv thov nyob deb ntawm ntau hom fiber ntau tuaj yeem ua tau raws li qhov xav tau ntawm 90 feem pua ntawm cov pob txha siv ntawm cov ntaub ntawv chaw. Los ntawm qhov xwm txheej tam sim no ntawm domestic thiab txawv teb chaws Internet loj heev, 400gbase-sr8 yog ib qho kev cog lus rau daim ntawv thov qauv.
