Amafuna fiber yambiri
Ndi kukhazikitsidwa kwa maukonde a m'badwo watsopano komanso kuchuluka kwa zida za intaneti za Zinthu, malinga ndi kuyerekezera kwina, kuchuluka kwawo 50 biliyoni m'zaka zitatu - kuchuluka kwa magalimoto padziko lonse lapansi kudzangowonjezeka. Deloitte akuti zida za fiber optic zomwe zilipo, zomwe ndi maziko a maukonde a 5G, sizingakhale zokwanira kuthana ndi katundu wotere. Malingaliro a bungwe lowunikira amathandizidwa ndi ndi opereka mtambo.
Kuti athetse vutoli, mabungwe ochulukirapo akugwira ntchito pa machitidwe omwe amawonjezera kutuluka kwa "optics". Imodzi mwa njira zothetsera hardware inapangidwa ndi Ciena - imatchedwa WaveLogic 5. Malingana ndi akatswiri a kampaniyo, purosesa yatsopanoyo imatha kupereka mitengo yotumizira deta mpaka 800 Gbit / s pamtunda umodzi.
Momwe yankho latsopanoli limagwirira ntchito
Ciena adapereka zosintha ziwiri za purosesa ya WaveLogic 5. Yoyamba imatchedwa WaveLogic 5 Extreme. Ndi chithunzi , yomwe imagwira ntchito ngati purosesa ya digito () fiber optic network. DSP imasintha chizindikiro kuchokera kumagetsi kupita ku kuwala ndi mosemphanitsa.
WaveLogic 5 Extreme imathandizira kutulutsa kwa fiber kuchokera ku 200 mpaka 800 Gbps - kutengera mtunda womwe chizindikirocho chiyenera kutumizidwa. Kuti musamutsire deta moyenera, Ciena adayambitsa pulogalamu ya processor algorithm yopangira kuthekera kwa gulu la nyenyezi ( - PCS).
Kuwundana uku ndi gulu la matalikidwe a mfundo (mfundo) pazizindikiro zopatsirana. Pazigawo zilizonse zamagulu a nyenyezi, algorithm ya PCS imawerengera kuthekera kwachinyengo cha data ndi mphamvu zomwe zimafunikira kutumiza chizindikirocho. Pambuyo pake, amasankha matalikidwe omwe chiΕ΅erengero cha chizindikiro ndi phokoso ndi kugwiritsa ntchito mphamvu kudzakhala kochepa.
Purosesa imagwiritsanso ntchito njira yowongolera zolakwika zamtsogolo () ndi ma frequency division multiplexing (). An encryption algorithm imagwiritsidwa ntchito kuteteza zidziwitso zofalitsidwa .
Kusintha kwachiwiri kwa WaveLogic 5 ndi mndandanda wa ma plug-in Nano Optical modules. Amatha kutumiza ndi kulandira deta pa liwiro la 400 Gbps. Ma modules ali ndi mawonekedwe awiri - QSFP-DD ndi CFP2-DCO. Yoyamba ndi yaying'ono kukula kwake ndipo idapangidwira 200 kapena 400GbE maukonde. Chifukwa cha liwiro lalikulu la kulumikizana komanso kugwiritsa ntchito mphamvu pang'ono, QSFP-DD ndiyoyenera mayankho a data center. Fomu yachiwiri, CFP2-DCO, imagwiritsidwa ntchito kutumiza deta pamtunda wa makilomita mazana, kotero idzagwiritsidwa ntchito muzitsulo za 5G ndi zipangizo zoperekera chithandizo cha intaneti.
WaveLogic 5 idzagulitsidwa mu theka lachiwiri la 2019.

Ubwino ndi kuipa kwa purosesa
WaveLogic 5 Extreme inali imodzi mwa mapurosesa oyamba pamsika kuti atumize deta pamtunda umodzi wa 800 Gbps. Pamayankho ambiri ampikisano, chiwerengerochi ndi 500-600 Gbit/s. Ciena amapindula ndi 50% yowonjezera kuwala kwa njira ndikuwonjezeka ndi 20%.
Koma pali vuto limodzi - ndi kuponderezedwa kwa chizindikiro komanso kuwonjezeka kwa liwiro la kusamutsa deta, pali chiopsezo cha kusokonezeka kwa chidziwitso. Zimawonjezeka ndi mtunda wowonjezereka. Pachifukwa ichi, purosesa zovuta potumiza chizindikiro pamtunda wautali. Ngakhale opanga amanena kuti WaveLogic 5 imatha kutumiza deta "kudutsa nyanja" pa liwiro la 400 Gbit / s.

Machitidwe owonjezera mphamvu ya fiber akupangidwanso ndi Infinite ndi Acacia. Yankho la kampani yoyamba limatchedwa ICE6 (ICE - Infinite Capacity Engine). Zili ndi zigawo ziwiri - optical Integrated Circuit (PIC - Photonic Integrated Circuit) ndi purosesa ya digito mu mawonekedwe a ASIC chip. PIC mumanetiweki imasintha chizindikiro kuchokera ku kuwala kupita kumagetsi ndi mosemphanitsa, ndipo ASIC imayang'anira kuchulukitsa kwake.
Mbali yapadera ya ICE6 ndikusinthasintha kwa siginecha (). Purosesa ya digito imagawaniza kuwala kwa utali wina wake kukhala ma frequency owonjezera, omwe amakulitsa kuchuluka kwa milingo yomwe ilipo ndikuwonjezera kuchulukira kwa siginecha. Zikuyembekezeka kuti ICE6, monga WaveLogic, ipereka mitengo yosinthira deta munjira imodzi pamlingo wa 800 Gbit/s. Chogulitsacho chiyenera kugulitsidwa kumapeto kwa 2019.
Ponena za Acacia, mainjiniya ake adapanga gawo la AC1200. Idzapereka kuthamanga kwa data ku 600 Gbit / s. Kuthamanga uku kumatheka pogwiritsa ntchito mapangidwe a 3D a gulu la nyenyezi: ma aligorivimu mu gawoli amasintha pafupipafupi kagwiritsidwe ntchito ka mfundo ndi malo awo mu kuwundana, kusintha mphamvu ya njira.
Zikuyembekezeka kuti mayankho atsopano a hardware adzawonjezera kutulutsa kwa kuwala kwa fiber osati patali patali mkati mwa mzinda umodzi kapena dera, komanso mtunda wautali. Kuti achite izi, mainjiniya amangoyenera kuthana ndi zovuta zomwe zimagwirizanitsidwa ndi njira zaphokoso. Kuchulukitsa kuchuluka kwa maukonde apansi pamadzi kudzakhala ndi zotsatira zabwino pazantchito za IaaS ndi makampani akuluakulu a IT, chifukwa "Β» theka la magalimoto odutsa pansi pa nyanja.
