Mugadziri wemidziyo yeTerecommunication Ciena akaratidzira optical sign processing system. Ichawedzera kukurumidza kwekufambisa data mu optical fiber kusvika ku800 Gbit/s.
Pasi pekucheka - pamusoro pemitemo yekushanda kwayo.

Inoda imwe fiber
Nekutangwa kwemanetiweki echizvarwa chitsva uye kuwanda kweInternet yezvinhu zvishandiso, maererano nekumwe fungidziro, nhamba yavo. 50 bhiriyoni mumakore matatu - huwandu hwetraffic traffic huchawedzera chete. Deloitte anoti iyo iripo fiber optic zvivakwa, inova hwaro hwe5G network, haizokwane kubata mutoro wakadaro. Maonero esangano rekuongorora anotsigirwa ne uye vanopa makore.
Kugadzirisa mamiriro acho ezvinhu, masangano akawanda uye akawanda ari kushanda pazvirongwa zvinowedzera kubuda kwe "optics". Imwe yezvigadziriso zvehardware yakagadzirwa naCiena - inonzi WaveLogic 5. Maererano nevanjiniya vekambani, purosesa itsva inokwanisa kupa mazinga ekufambisa data kusvika ku800 Gbit / s pane imwe wavelength.
Kuti mhinduro itsva inoshanda sei
Ciena akapa zvigadziriso zviviri zveWaveLogic 5. Yekutanga inonzi WaveLogic 5 Extreme. Idhiyagiramu , iyo inoshanda sedhijitari chiratidzo processor () fiber optic network. DSP inoshandura chiratidzo kubva kumagetsi kuenda kumaziso uye zvakasiyana.
WaveLogic 5 Yakanyanya inotsigira fiber throughput kubva pa200 kusvika 800 Gbps - zvichienderana nedaro rinoda kutumirwa chiratidzo. Kuti uwane mamwe mashandiro ekufambisa data, Ciena akaunza mune processor firmware algorithm ye probabilistic kuumbwa kwechiratidzo chenyeredzi ( - PCS).
Iri boka renyeredzi seti yeamplitude values ββββ(mapoinzi) ezviratidzo zvinotapurirwa. Kune imwe neimwe yemapoinzi enyeredzi, iyo PCS algorithm inoverengera mukana wehuori hwedata uye simba rinodiwa kutumira chiratidzo. Pashure pacho, anosarudza amplitude iyo iyo chiratidzo-ku-ruzha chiyero uye kushandiswa kwesimba kuchave kushoma.
Iyo processor zvakare inoshandisa yekumberi kukanganisa kugadzirisa algorithm () uye frequency division multiplexing () An encryption algorithm inoshandiswa kuchengetedza inofambiswa ruzivo .
Yechipiri shanduko yeWaveLogic 5 inoteedzana yeplug-in Nano Optical modules. Vanogona kutumira uye kugamuchira data nekumhanya kusvika ku400 Gbps. Iwo ma modules ane maviri mafomu zvinhu - QSFP-DD uye CFP2-DCO. Yekutanga idiki muhukuru uye yakagadzirirwa 200 kana 400GbE network. Nekuda kwekumhanya kwakanyanya kwekubatanidza uye kuderera kwesimba rekushandisa, QSFP-DD yakakodzera kune data center mhinduro. Yechipiri fomu factor, CFP2-DCO, inoshandiswa kutumira data pamusoro pemadaro emazana emakiromita, saka ichashandiswa mumitambo ye5G uye Internet service provider infrastructure.
WaveLogic 5 ichaenderera mberi kutengeswa muhafu yechipiri ye2019.

Zvakanakira uye zvakaipa zve processor
WaveLogic 5 Yakanyanya yaive imwe yekutanga processors pamusika kufambisa data pane imwechete wavelength pa800 Gbps. Kune akawanda emakwikwi mhinduro, iyi nhamba i500-600 Gbit/s. Ciena inobatsira kubva ku50% yakawanda optical chiteshi kugona uye yakawedzera pa20%.
Asi pane kuoma kumwe - nekumanikidza kwechiratidzo uye kuwedzera kwekukurumidza kwekufambisa data, kune njodzi yekukanganisa ruzivo. Inowedzera nekuwedzera kureba. Nechikonzero ichi, processor matambudziko pakutumira chiratidzo padaro refu. Kunyangwe vagadziri vacho vachiti WaveLogic 5 inokwanisa kufambisa data "mhiri kwemakungwa" nekumhanya kwe400 Gbit/s.
Analogs
Masisitimu ekuwedzera fiber huwandu ari kuvandudzwa neInfinite neAcacia. Mhinduro yekambani yekutanga inonzi ICE6 (ICE - Infinite Capacity Engine). Iyo ine zvikamu zviviri - optical integrated circuit (PIC - Photonic Integrated Circuit) uye digital signal processor muchimiro cheASIC chip. Iyo PIC mumatiweki inoshandura chiratidzo kubva kumagetsi kuenda kumagetsi uye zvichipesana, uye iyo ASIC ine basa rekuwedzeredza kwayo.
Chinhu chakakosha cheICE6 kupuruzira modulation yechiratidzo () Dhijitari processor inotsemura mwenje weimwe wavelength mune yekuwedzera subcarrier frequencies, iyo inowedzera huwandu hwemazinga aripo uye inowedzera spectral density yechiratidzo. Zvinotarisirwa kuti ICE6, seWaveLogic, ichapa mazinga ekufambisa data mune imwe chiteshi pamwero we800 Gbit/s. Chigadzirwa chinofanira kutengeswa panopera 2019.
Kana iri Acacia, mainjiniya ayo akagadzira iyo AC1200 module. Ichapa data kumhanyisa kumhanya kwe600 Gbit/s. Uku kumhanyisa kunowanikwa uchishandisa 3D kuumbwa kwechiratidzo chenyeredzi: algorithms mumodule inoshandura otomatiki kuwanda kwekushandiswa kwemapoinzi uye chinzvimbo chavo muboka renyeredzi, kugadzirisa chiteshi chiteshi.
Zvinotarisirwa kuti zvigadziriso zvitsva zvehardware zvichawedzera kubuda kwefiber optical kwete chete pamusoro pemafaro mukati meguta rimwe kana dunhu, asiwo nepamusoro madaro marefu. Kuti uite izvi, mainjiniya anongofanirwa kukunda matambudziko anoenderana nematanho ane ruzha. Kuwedzera huwandu hwemagetsi epasi pemvura kuchave nemhedzisiro yakanaka pamhando yebasa revanopa IaaS nemakambani makuru eIT, vachipihwa kuti "Β»hafu yetraffic inofambiswa pasi pegungwa.
