Kufuneka ngakumbi ifayibha
Ngokuqaliswa kothungelwano lwesizukulwana esitsha kunye nokwanda kwezixhobo ze-Intanethi zeZinto, ngokutsho kolunye uqikelelo, inani labo. I-50 yeebhiliyoni kwiminyaka emithathu - umthamo wezithuthi zehlabathi uya kwanda kuphela. U-Deloitte uthi isiseko se-fiber optic ekhoyo, esisisiseko sothungelwano lwe-5G, asiyi kukwanela ukusingatha umthwalo onjalo. Imbono ye-arhente yohlalutyo ixhaswa ngu nababoneleli ngamafu.
Ukulungisa le meko, imibutho emininzi isebenza kwiinkqubo ezandisa i-"optics". Esinye sezisombululo ze-hardware saphuhliswa yi-Ciena - ibizwa ngokuba yi-WaveLogic 5. Ngokutsho kweenjineli zenkampani, iprosesa entsha iyakwazi ukubonelela ngemilinganiselo yokudlulisa idatha ukuya kwi-800 Gbit / s kwi-wavelength enye.
Sisebenza njani isisombululo esitsha
UCiena ubonise iinguqulelo ezimbini zeprosesa yeWaveLogic 5. Eyokuqala ibizwa ngokuba yiWaveLogic 5 Extreme. Ngumzobo , esebenza njengeprosesa yesignali yedijithali () inethiwekhi yefiber optic. I-DSP iguqula umqondiso ukusuka kumbane ukuya kwi-optical kwaye ngokuphambeneyo.
I-WaveLogic 5 Extreme ixhasa i-fiber throughput ukusuka kwi-200 ukuya kwi-800 Gbps - kuxhomekeke kumgama apho umqondiso kufuneka uthunyelwe. Kugqithiso lwedatha olusebenza ngakumbi, uCiena wazisa kwiprosesa yenkqubo ialgorithm yokwenziwa kwekroza lophawu olunokwenzeka ( -PCS).
Eli qela leenkwenkwezi yiseti yamaxabiso e-amplitude (amanqaku) kwiimpawu ezithunyelwayo. Kwinqaku ngalinye kwi-constellation, i-algorithm ye-PCS ibala amathuba okonakala kwedatha kunye namandla afunekayo ukuthumela umqondiso. Emva koko, ukhetha i-amplitude apho umlinganiselo we-signal-to-noise kunye nokusetyenziswa kwamandla kuya kuba yinto encinci.
Umqhubekekisi kwakhona usebenzisa ialgorithm yolungiso lwemposiso () kunye nolwahlulo lokuphindaphinda (). I-encryption algorithm isetyenziselwa ukukhusela ulwazi olugqithisiweyo .
Ukuguqulwa kwesibini kwe-WaveLogic 5 luhlu lwe-plug-in Nano optical modules. Bangakwazi ukuthumela kwaye bafumane idatha ngesantya ukuya kwi-400 Gbps. Iimodyuli zinemiba emibini yeefom - i-QSFP-DD kunye ne-CFP2-DCO. Eyokuqala incinci ngobukhulu kwaye yenzelwe i-200 okanye i-400GbE inethiwekhi. Ngenxa yesantya esiphezulu sokuxhuma kunye nokusetyenziswa kwamandla aphantsi, i-QSFP-DD ifanelekile kwizisombululo zeziko ledatha. Ifom yesibini yefom, i-CFP2-DCO, isetyenziselwa ukuthumela idatha kumgama wamakhulu eekhilomitha, ngoko iya kusetyenziswa kwiinethiwekhi ze-5G kunye neziseko zokubonelela ngenkonzo ye-Intanethi.
I-WaveLogic 5 iya kuthengiswa kwisiqingatha sesibini se-2019.

Izinto eziluncedo kunye nokungalunganga kweprosesa
I-WaveLogic 5 Extreme yayiyenye yeeprosesa zokuqala kwimarike ukuhambisa idatha kwi-wavelength enye kwi-800 Gbps. Kwizisombululo ezininzi zokukhuphisana, eli nani li-500-600 Gbit / s. I-Ciena ixhamla kwi-50% yamandla e-optical channel ngakumbi kwaye yanda ngama-20%.
Kodwa kukho ubunzima obunye - ngokunyanzeliswa komqondiso kunye nokunyuka kwesantya sokudlulisa idatha, kukho umngcipheko wokuphazamiseka kolwazi. Iyanyuka ngokunyuka komgama. Ngenxa yesi sizathu, iprosesa ubunzima xa kuthunyelwa uphawu kwimigama emide. Nangona abaphuhlisi bathi i-WaveLogic 5 iyakwazi ukuthumela idatha "kulwandle lonke" ngesantya se-400 Gbit / s.
Analogs
Iinkqubo zokwandisa umthamo wefayibha nazo ziphuhliswa yi-Infinite kunye ne-Acacia. Isisombululo senkampani yokuqala sibizwa ngokuba yi-ICE6 (ICE - Infinite Capacity Engine). Iqukethe amacandelo amabini - i-optical integrated circuit (PIC - I-Photonic Integrated Circuit) kunye neprosesa yesignali yedijithali ngendlela ye-chip ye-ASIC. I-PIC kuthungelwano iguqula umqondiso kwi-optical ukuya kumbane kunye ne-vice versa, kwaye i-ASIC inoxanduva lokuphindaphinda kwayo.
Inqaku elikhethekileyo le-ICE6 kukumodareyitha kwe-pulse yesiginali (). Iprosesa yedijithali yahlula ukukhanya kobude obuthile bobude bezakhelo ezongezelelweyo ze-subcarrier frequencies, eyandisa inani lamanqanaba akhoyo kwaye yandise ingxinano ye-spectral yomqondiso. Kulindeleke ukuba i-ICE6, njenge-WaveLogic, iya kubonelela ngemilinganiselo yokudlulisa idatha kwitshaneli enye kwinqanaba le-800 Gbit / s. Imveliso kufuneka iqhubeke ithengiswa ekupheleni kuka-2019.
Ngokuphathelele i-Acacia, iinjineli zayo zenze imodyuli ye-AC1200. Iya kubonelela ngesantya sothumelo lwedatha ye-600 Gbit / s. Esi santya sifezekiswa ngokusebenzisa i-3D ukubunjwa kwe-constellation ye-signal: i-algorithms kwimodyuli itshintsha ngokuzenzekelayo ukuphindaphinda kokusetyenziswa kwamanqaku kunye nesikhundla sabo kwi-constellation, ukulungelelanisa umthamo wesiteshi.
Kulindeleke ukuba izisombululo ezitsha zehardware ziya kwandisa i-throughput yefiber optical hayi kuphela kwimigama phakathi kwesixeko esinye okanye ummandla, kodwa nakwimigama emide. Ukwenza oku, iinjineli kufuneka zoyise nje ubunzima obunxulumene nemijelo enengxolo. Ukwandisa umthamo wothungelwano olungaphantsi kwamanzi kuya kuba nefuthe elihle kumgangatho weenkonzo zababoneleli be-IaaS kunye neenkampani ezinkulu ze-IT, ngenxa yokuba "Β» Isiqingatha setrafikhi sisasazwa kumgangatho wolwandle.
