Txheej ceev module ntuag
Kev sib txuas lus kho qhov muag hluav taws xob yog ib hom kev xa hluav taws xob uas siv hluav taws xob hauv zos hauv oscillator lub teeb kom pom kev sib txheeb. Nws siv DSP. Nws muaj peev xwm mus txog los yog siab dua qhov kis tau tus mob ntawm 100 gigabits, xav tau tsuas yog khub ntawm cov kho qhov muag kom xa terabits ntawm cov ntaub ntawv, feem ntau rau kev siv ntev.
Xis kom zoo dua
Lub ntsiab zoo ntawm cov kev hloov kho qhov muag hloov kho yog cov DSP nti nti thiab cov hluav taws xob kev faib hluav taws xob (EDC), uas tsis muaj nyob hauv PAM4. Qhov nti no tsis tas yuav muaj daim nyias nyias DSP thiab kev faib khoom tawg, tab sis siv EDC los txhim kho lub zog.
Coherent optical devices tuaj yeem kis tau ntawm qhov kev ncua deb txog 1000km, ua kom cov kev txhawb nqa ntev tsis tas yuav tsum tau siv cov kev pabcuam thib peb. Kev siv cov txuj ci siv hauv kev sib txuas lus hauv xov tooj cua, kev sib koom ua ke kom zoo dua qub tuaj yeem txhim kho tus neeg txais kev nkag siab thaum tswj kev xaiv nyob twj ywm, uas ua rau cov channel qhov nrug kom zoo tab sis tseem cais tawm.
Txheej sib xws tsis zoo
Txawm hais tias CFP thiab CFP2 digital coherent optics tuaj yeem ua haujlwm tau sai thiab muaj txiaj ntsig, lawv siv ntau lub zog thiab tus nqi ntau dua thaum piv rau lwm pob, thiab cov kev cuam tshuam no tuaj yeem cuam tshuam tag nrho cov nqi khiav lag luam, tawm tsam kev sib tw rau cov tuam txhab uas xav tau zoo 100G DWDM pluggable optical modules tsis pub dhau lawv cov nyiaj txiag.
Lwm qhov tsis zoo ntawm cov kev sib koom ua ke kho qhov muag yog tias ob DSP los ntawm tib tus neeg muag khoom yuav xav tau ntawm ob qhov kawg ntawm qhov txuas. DSPs sib txawv tsis tuaj yeem ua haujlwm ua ke, thiab qee qhov xwm txheej kab npav yuav tsum yog zoo ib yam.
Xaus
Yuav suav tag nrho, 100G PAM4 optical modules tuaj yeem xaiv tsis pub dhau 80km, 100G coherent optical modules tuaj yeem xaiv dhau 80km, thiab txhua qhov sib txuas ntawm cov kho qhov muag tau siv rau hauv cov chaw zov me nyuam raws li lawv cov tseev kom muaj. Cov cuab yeej nrov DWDM tau txuas rau 200G kab nrawm, pab tswj cov nyom thiab tus nqi ntawm cov ntaub ntawv sib txuas lus. DWDM yuav yog thawj qhov sib txuam rau 100G systems piv rau passive multiplexers uas pab tau cov kev pabcuam hauv qab 10G rau ntau cov channel CWDM / DWDM kev sib txuas.
