Kev sib txuas lus cov cuab yeej tsim tawm Ciena nthuav tawm cov teeb liab kho qhov muag. Nws yuav ua rau kom cov ntaub ntawv kis ceev hauv optical fiber ntau rau 800 Gbit / s.

Xav tau fiber ntau
Nrog rau kev tshaj tawm cov tiam tshiab network thiab kev loj hlob ntawm Internet ntawm Yam khoom siv, raws li qee qhov kev kwv yees, lawv tus lej 50 billion nyob rau hauv peb lub xyoos - lub ntim ntawm lub ntiaj teb no tsheb yuav tsuas nce. Deloitte hais tias cov khoom siv fiber ntau optic uas twb muaj lawm, uas yog lub hauv paus rau 5G tes hauj lwm, yuav tsis txaus los tuav cov khoom ntawd. Lub koom haum tshuaj ntsuam xyuas qhov kev xav tau txhawb nqa los ntawm thiab huab muab kev pabcuam.
Txhawm rau kho qhov teeb meem no, ntau thiab ntau lub koom haum tau ua haujlwm ntawm cov tshuab uas ua rau muaj kev nce qib ntawm "optics". Ib qho ntawm cov kev daws teeb meem kho vajtse tau tsim los ntawm Ciena - nws yog hu ua WaveLogic 5. Raws li lub tuam txhab engineers, tus processor tshiab muaj peev xwm muab cov ntaub ntawv hloov pauv mus txog 800 Gbit / s ntawm ib lub wavelength.
Qhov kev daws teeb meem tshiab ua haujlwm li cas
Ciena nthuav tawm ob qhov kev hloov kho ntawm WaveLogic 5 processor. Thawj yog hu ua WaveLogic 5 Extreme. Nws yog daim duab , uas ua raws li lub teeb liab digital processor () fiber ntau optic network. DSP hloov lub teeb liab los ntawm hluav taws xob mus rau optical thiab vice versa.
WaveLogic 5 Extreme txhawb nqa fiber ntau los ntawm 200 mus rau 800 Gbps - nyob ntawm qhov kev ncua deb uas yuav tsum tau xa cov teeb liab. Txhawm rau hloov cov ntaub ntawv muaj txiaj ntsig ntau dua, Ciena tau qhia rau hauv processor firmware ib qho algorithm rau qhov tshwm sim tshwm sim ntawm lub teeb liab constellation ( - PCS).
Lub constellation no yog ib txheej ntawm amplitude qhov tseem ceeb (cov ntsiab lus) rau kis tau tus mob. Rau txhua lub ntsiab lus constellation, PCS algorithm xam qhov tshwm sim ntawm cov ntaub ntawv kev noj nyiaj txiag thiab lub zog yuav tsum tau xa cov teeb liab. Tom qab ntawd, nws xaiv lub amplitude uas lub teeb liab-rau-suab nrov piv thiab lub zog noj yuav tsawg.
Lub processor kuj tseem siv cov kev ua yuam kev rau pem hauv ntej kho algorithm () thiab ntau zaus division multiplexing (). Ib qho encryption algorithm yog siv los tiv thaiv cov ntaub ntawv xa mus .
Qhov thib ob kev hloov kho ntawm WaveLogic 5 yog ib tug series ntawm plug-in Nano optical modules. Lawv tuaj yeem xa thiab txais cov ntaub ntawv ntawm qhov nrawm txog 400 Gbps. Cov modules muaj ob hom qauv - QSFP-DD thiab CFP2-DCO. Thawj yog me me thiab tsim rau 200 lossis 400GbE tes hauj lwm. Vim muaj kev sib txuas siab ceev thiab siv hluav taws xob tsawg, QSFP-DD yog qhov tsim nyog rau cov ntaub ntawv chaw daws teeb meem. Daim ntawv thib ob, CFP2-DCO, yog siv los xa cov ntaub ntawv hla ntau pua mais deb, yog li nws yuav siv rau hauv 5G tes hauj lwm thiab cov chaw muab kev pabcuam hauv Internet.
WaveLogic 5 yuav mus muag hauv ib nrab xyoo 2019.

Qhov zoo thiab qhov tsis zoo ntawm lub processor
WaveLogic 5 Extreme yog ib qho ntawm thawj cov txheej txheem ntawm kev ua lag luam xa cov ntaub ntawv ntawm ib lub wavelength ntawm 800 Gbps. Rau ntau txoj kev sib tw, daim duab no yog 500-600 Gbit / s. Ciena tau txais txiaj ntsig los ntawm 50% ntau lub peev xwm kho qhov muag thiab nce ntxiv rau 20%.
Tab sis muaj ib qho nyuaj - nrog cov teeb liab compression thiab nce cov ntaub ntawv hloov ceev, muaj kev pheej hmoo ntawm cov ntaub ntawv distortion. Nws nce nrog nce nyob deb. Rau qhov no processor teeb meem thaum xa cov teeb liab hla kev deb. Txawm hais tias cov neeg tsim khoom hais tias WaveLogic 5 muaj peev xwm xa cov ntaub ntawv "hla dej hiav txwv" ntawm qhov nrawm ntawm 400 Gbit / s.
Analogs
Cov tshuab ua kom muaj peev xwm fiber ntau kuj tau tsim los ntawm Infinite thiab Acacia. Thawj lub tuam txhab kev daws teeb meem yog hu ua ICE6 (ICE - Infinite Capacity Engine). Nws muaj ob yam khoom - ib qho kev sib koom ua ke kho qhov muag (PIC - Photonic Integrated Circuit) thiab cov teeb liab digital processor hauv daim ntawv ntawm ASIC nti. PIC hauv tes hauj lwm hloov cov teeb liab ntawm qhov muag mus rau hluav taws xob thiab rov ua dua, thiab ASIC yog lub luag haujlwm rau nws cov multiplexing.
Ib qho tshwj xeeb ntawm ICE6 yog pulse modulation ntawm lub teeb liab (). Lub tshuab hluav taws xob digital faib lub teeb ntawm qee qhov wavelength mus rau hauv cov khoom siv hluav taws xob ntxiv, uas nthuav tawm cov qib uas muaj thiab ua rau kom cov spectral ceev ntawm lub teeb liab. Nws cia siab tias ICE6, zoo li WaveLogic, yuav muab cov ntaub ntawv hloov pauv hauv ib channel ntawm qib 800 Gbit / s. Cov khoom yuav tsum tau muag thaum kawg ntawm 2019.
Raws li rau Acacia, nws cov engineers tsim AC1200 module. Nws yuav muab cov ntaub ntawv kis ceev ntawm 600 Gbit / s. Qhov kev ceev no tau ua tiav siv 3D tsim ntawm lub cim hnub qub: algorithms nyob rau hauv lub module cia li hloov qhov zaus ntawm kev siv cov ntsiab lus thiab lawv txoj hauj lwm nyob rau hauv lub constellation, kho lub peev xwm channel.
Nws cia siab tias cov kev daws teeb meem tshiab yuav ua rau muaj kev cuam tshuam ntawm fiber ntau optical tsis tsuas yog nyob rau hauv ib lub nroog los yog cheeb tsam, tab sis kuj nyob ntev dua. Ua li no, engineers tsuas yog yuav tsum tau kov yeej cov teeb meem cuam tshuam nrog cov suab nrov. Kev nce lub peev xwm ntawm cov kev sib txuas hauv qab dej yuav muaj qhov cuam tshuam zoo rau cov kev pabcuam zoo ntawm IaaS cov chaw muab kev pabcuam thiab cov tuam txhab IT loj, vim tias lawv "Β» ib nrab ntawm cov tsheb thauj mus los raws dej hiav txwv pem teb.
