E hloka fiber e eketsehileng
Ka ho hlahisoa ha marang-rang a macha le ho ata ha lisebelisoa tsa Inthanete tsa Lintho, ho latela likhakanyo tse ling, palo ea tsona. 50 limilione tse likete ka lilemo tse tharo - palo ea sephethephethe sa lefats'e e tla eketseha feela. Deloitte o re lisebelisoa tse teng tsa fiber optic, e leng motheo oa marang-rang a 5G, li ke ke tsa lekana ho sebetsana le mojaro o joalo. Maikutlo a mokhatlo oa analytical a tšehetsoa ke le bafani ba maru.
Ho lokisa boemo, mekhatlo e mengata e ntse e sebetsa ho litsamaiso tse eketsang tlhahiso ea "optics". E 'ngoe ea litharollo tsa hardware e ile ea hlahisoa ke Ciena - e bitsoa WaveLogic 5. Ho ea ka baenjiniere ba k'hamphani, processor e ncha e khona ho fana ka litekanyetso tsa ho fetisetsa data ho fihlela ho 800 Gbit / s ka leqhubu le le leng.
Kamoo tharollo e ncha e sebetsang kateng
Ciena o hlahisitse liphetoho tse peli tsa processor ea WaveLogic 5. Ea pele e bitsoa WaveLogic 5 Extreme. Ke setšoantšo , e sebetsang e le processor ea matšoao a dijithale () marang-rang a fiber optic. DSP e fetolela lets'oao ho tloha ho motlakase ho ea ho optical le ka tsela e fapaneng.
WaveLogic 5 Extreme e ts'ehetsa phallo ea fiber ho tloha ho 200 ho isa ho 800 Gbps - ho latela sebaka seo lets'oao le hlokang ho romelloa ho lona. Bakeng sa phetisetso ea data e sebetsang hantle haholoanyane, Ciena o kentse algorithm ho processor firmware bakeng sa sebopeho sa probabilistic ea sehlopha sa linaleli sa matšoao ( - li-PCS).
Sehlopha sena sa linaleli ke sete sa boleng ba amplitude (lintlha) bakeng sa matšoao a fetisoang. Bakeng sa ntlha e 'ngoe le e' ngoe ea lihlopha tsa linaleli, algorithm ea PCS e lekanya monyetla oa bobolu ba data le matla a hlokahalang ho romela letšoao. Ka mor'a moo, o khetha amplitude eo karo-karolelano ea pontšo-ho-lerata le tšebeliso ea matla e tla ba e fokolang.
Prosesa e boetse e sebelisa algorithm ea ho lokisa phoso ea pele () le frequency division multiplexing (). Algorithm ea encryption e sebelisoa ho sireletsa litaba tse fetisoang .
Phetoho ea bobeli ea WaveLogic 5 ke letoto la li-plug-in Nano optical modules. Ba ka romella le ho amohela data ka lebelo ho fihla ho 400 Gbps. Li-module li na le lintlha tse peli tsa mefuta - QSFP-DD le CFP2-DCO. Ea pele e nyane ka boholo mme e etselitsoe marang-rang a 200 kapa 400GbE. Ka lebaka la lebelo le phahameng la khokahanyo le tšebeliso e tlaase ea matla, QSFP-DD e loketse litharollo tsa setsi sa data. Ntho ea bobeli ea mofuta, CFP2-DCO, e sebelisetsoa ho romela lintlha ho feta lik'hilomithara tse makholo, kahoo e tla sebelisoa ho marang-rang a 5G le lisebelisoa tsa litšebeletso tsa Inthanete.
WaveLogic 5 e tla tsoela pele ho rekisoa halofo ea bobeli ea 2019.

Melemo le mefokolo ea processor
WaveLogic 5 Extreme e ne e le e 'ngoe ea li-processor tsa pele' marakeng ho fetisa data ka bolelele bo le bong ho 800 Gbps. Bakeng sa litharollo tse ngata tsa tlholisano, palo ena ke 500-600 Gbit / s. Ciena e rua molemo ho 50% ho feta matla a mocha oa optical le ho eketseha ka 20%.
Empa ho na le bothata bo le bong - ka khatello ea matšoao le ho eketseha ha lebelo la phetisetso ea data, ho na le kotsi ea ho sotha tlhahisoleseling. E eketseha ka sebaka se ntseng se eketseha. Ka lebaka lena, processor mathata ha o romela sesupo ka sebaka se selelele. Le hoja bahlahisi ba re WaveLogic 5 e khona ho fetisetsa boitsebiso "ho pholletsa le maoatle" ka lebelo la 400 Gbit / s.

Mekhoa ea ho eketsa matla a fiber le eona e ntse e ntlafatsoa ke Infinite le Acacia. Tharollo ea k'hamphani ea pele e bitsoa ICE6 (ICE - Infinite Capacity Engine). E na le likarolo tse peli - potoloho e kopantsoeng ea optical (PIC - Photonic Integrated Circuit) le mochine oa motlakase oa digital ka mokhoa oa ASIC chip. PIC ho marang-rang e fetola letšoao ho tloha ho optical ho ea ho motlakase le ka tsela e fapaneng, 'me ASIC e ikarabella bakeng sa multiplexing ea eona.
Karolo e ikhethang ea ICE6 ke ho feto-fetoha ha molumo oa lets'oao (). Mochini oa dijithale o arola leseli la bolelele bo itseng ho ba maqhubu a tlatselletsang a subcarrier, a holisang palo ea maemo a teng le ho eketsa bongata ba ponelopele ea lets'oao. Ho lebelletsoe hore ICE6, joalo ka WaveLogic, e tla fana ka litefiso tsa phetisetso ea data mocha o le mong boemong ba 800 Gbit / s. Sehlahisoa se lokela ho tsoela pele ho rekisoa bofelong ba 2019.
Ha e le Acacia, baenjiniere ba eona ba thehile module ea AC1200. E tla fana ka lebelo la phetisetso ea data ea 600 Gbit / s. Lebelo lena le finyelloa ho sebelisoa sebopeho sa 3D sa sehlopha sa linaleli sa lets'oao: li-algorithms tsa mojulung li fetola ka botsona makhetlo a ts'ebeliso ea lintlha le boemo ba tsona sehlopheng sa linaleli, ho lokisa bokhoni ba mocha.
