Muna Nyamavhuvhu 2019, Russia, kekutanga pasirese (Hongu, ichokwadi), yakaita purojekiti yekutengeserana yewireless redundancy yebackbone optical cable ine huwandu hwe40 Gbit / s. Operator Unity, inotsigira yeNorilsk Nickel, yakashandisa chiteshi kuendesa 11-kilomita isina waya backup mhiri kweYenisei.
Nguva nenguva mumapepanhau, kusanganisira paHabrΓ©, vanoonekwa . Izvo zvinonakidza kubva pakuona kwekufambira mberi kwetekinoroji, asi izvi zvinogara zvichiongororwa bvunzo. Uye heino purojekiti chaiyo yekutengeserana, uye kwete mumamiriro eSilicon Valley kana yunivhesiti yeEurope, asi mune taiga paArctic Circle. Zvinoshamisa kuti inyika hombe uye yakaoma nzvimbo uye mamiriro ekunze anogadzira zvimiro zvezvirongwa zvinopa akanakisa marabhoritari ekutsvagisa mari yavo.
Yenguva yeazvino marekodhi asina waya:
- Dai 2013, pachiitiko chekuedza che 240 GHz sekuedza pamwe chete nemasayendisiti kubva kuKarlsruhe Institute of Technology, Radiometer Physics GmbH uye Fraunhofer Institute for Applied Solid State Physics. Signal frequency haisipo yekushandiswa kwekutengesa.
- Dai 2016: mu70/80 GHz renji, timu imwechete, asi seyedzo nyowani pama frequency akagoverwa mapurojekiti ekutengesa,
- November 2016: , Facebook Connectivity Lab research centre,
- January 2019, , Deutsche Telekom bvunzo saiti pane serial Ericsson midziyo, muna Chivabvu 2019, kukwidza malink akafanana panzvimbo imwechete yekuyedza kusvika 8 mumutsara akapa anenge zana Gbit/s,
- August 2019, , Norilsk operator "Kubatana" pane serial midziyo yeDOK LLC (St. Petersburg).
Sezvineiwo, pangadai pasina kana rekodhi yekutaurirana isina waya muArctic Circle dai yanga isiri yekudonha kweaizi paYenisei. Mhedzisiro yepurojekiti iyi inotevera - muna 2017, mushure mekunge maBig Three opareta aramba kusimudzira kutaurirana munzira yeTaimyr, iyo corporation PJSC MMC Norilsk Nickel, ichishandisa mari yayo, yakavaka hurefu hukuru (956 km) fiber-optic. musana (FOCL) kubva kuNovy Urengy kuenda kuNorilsk ine simba re40 Gbit/s. Iyi inzira yakaoma chaizvo, ichipfuura nemunzvimbo dzakaoma, uye vavaki vayo vakagamuchira mibairo yehurumende yebasa iri.
Imwe yematambudziko ekushanda yaive nzira ye40-gigabit fiber optic tambo mhiri kweYenisei pasina mabhiriji; zvakasarudzwa kuti zvimhanye pazasi perwizi, uye nekuvimbika, tambo dzinoverengeka dzakaiswa. Asi kukukurwa kweaizi kunokuvadza zviri nyore optics. Uyezve, ice drift paYenisei haisi chiitiko chezuva rimwe chete, uye hapana basa rekugadzirisa pamvura rinobvumirwa panguva iyi yose nekuda kwengozi huru yevanhu.
Pamusoro pemamwe tambo pazasi peYenisei, nzira yacho yakatsigirwa netambo isina waya yeredhiyo ye1 Gbit/cc telecommunication tower kumativi ese erwizi, muIgarka nemusha wePriluki (iyi nhepfenyuro inoonekwa. mumufananidzo wepamusoro - ndiro huru). Asi chii chinonzi 1 Gbit / s kupa iyo yose Norilsk indasitiri nharaunda kana kukanganisa optics ... - misodzi. Naizvozvo, munguva yekuvhuvhu-yechando ye2018-2019, iyo Norilsk opareta Unity, chikamu chechimiro chePJSC MMC Norilsk Nickel, yakatanga basa rekugadzira pakuvaka chiteshi chisina waya mhiri kweYenisei ine simba risiri rakaderera kune fiber- optic line.
Kukushamisika kwevanyanzvi veUnity, hapana yemhando dzenhare dzepasi rose dzakagamuchira zvikumbiro zvekupa michina ye40-gigabit isina waya chiteshi chinhambwe che11 km. Uye poindi apa ndiyo chaiyo musanganiswa wakaoma weiyo yakakwirira chiteshi kugona uye renji. Midziyo yemazuva ano yeserial ine simba re10 Gbit/s kana kupfuura ye70/80 GHz renji ine chinhu chakadai seyeshongedzo shoma. Izvi zvinokonzerwa nekuti neakaomesesa encoding zvirongwa seQAM128 kana QAM256 - uye ivo chete ndivo vanogona kupa kubuda kwe10 Gbit / s kana kupfuura - zvakaoma kupa chero yakakosha transmitter simba. Nzira dze 3-5 km dziri nyore, asi pa 11 km chiratidzo chekudzikisa chinova chakakura zvakanyanya uye hapana chinongedzo muchiyero che10GE chinogona kuwanikwa.
Dambudziko rakagamuchirwa nemugadziri wepamba kubva kuSt. . Aive atogadzira mazambuko eredhiyo aipa mutsara unodiwa. Uye pamberi pepurojekiti iyi, vakaedza 40 Gbit / s chiteshi muchimiro che4 vachishanda pamwe chete 10 Gbit / s mabhiriji eredhiyo panzvimbo yavo ye4 km yekuyedza, uye vaive nechivimbo chekuti zvaigoneka kuwana huwandu hwakadaro. Asi mukuita, hapana ari muindasitiri yezvekufonera akamboedza kubatanidza 4 parallel inoshanda mabhiriji eredhiyo e10 Gbit / s kure ne11 km.
Mushure mekugamuchira kurambwa kubva kumhando dzepasirese, mutengi, anomiririrwa neEdinstvo LLC, aive asina chokwadi chekuti midziyo yemumba yaizotarisana neprojekti. Naizvozvo, zvakasarudzwa kutanga kuisa imwe chete 10 Gbit/s redhiyo zambuko pamusoro pe11 km sedanho rekutyaira. Uye kana ikazviratidza zvakanaka, wobva wayera basa racho kusvika ku4 parallel inoshanda mabhiriji eredhiyo.
Kubva pane tekinoroji yekuona, hazvifanirwe zvachose kutumira 40 Gbit / s mune imwe chiteshi, zvese pamusoro pemhepo uye pamusoro peiyo optical tambo. Zviri nyore kuendesa data pamusoro akati wandei akafanana 10 Gbit/s "shinda". 10GE network michina yakachipa uye inowanikwa kupfuura 40GE switch. Mukuwedzera, "tambo" dzakafanana dzinopa kuvimbika kukuru kune chiteshi chose.
Asi pakanga paine dambudziko rekuti, kusiyana netambo yemaziso, uko chiratidzo pamwe chete nefibers hachikanganise mumwe neimwe nzira, nhepfenyuro dzeredhiyo dzinosangana nekupindirana, kusvika pakutadza kutaurirana. Izvi zvinobatwa nekushandisa zvakasiyana-siyana polarization yechiratidzo uye kuparadzira masaini ne frequency. Asi izvi zviri nyore kutaura, zvakanyanya kuoma kuita "mu Hardware". The St. Petersburg chikwata akaita redunhu vachishandisa guru microwave microcircuits (MMIC, Monolithic Microwave Integrated Circuit) kwakavakirwa gallium arsenide uye vaiva nechivimbo mu circuitry mhinduro yavo.
βMabhiriji eredhiyo emazuva ano echiyero che10GE pasi rese anogadzirwa pachishandiswa machipisi ekutengesa microwave. Munzvimbo iyi, hazvishande kuitisa vertically integrated development, kana zvese tekinoroji maitiro akaitwa mukambani imwe - kubva kusputtering microwave chips kusvika pakuunganidza zvikamu kuita chigadzirwa chakapedzwa. Izvi zvakangofanana nemakambani mangani anogadzira mabhodhi emakombuta akavakirwa pamachipisi kubva kuIntel ne AMD. Nekudaro, kusiyana neakawanda-akagadzirwa maPC mabhodhi, kumisikidza microwave machipisi, zvichizosimudzira chiratidzo uye kuchipa kune antenna kunoda hunyanzvi hwakakosha, uye izvi, ndizvozvo, inyaya yekambani Know-How, "akadaro Valery Salomatov, chirongwa. maneja DOK LLC.
Mutyairi 10 Gbit/s redhiyo bhiriji modhi PPC-10G-E-HP akabudirira kushanda pashongwe pamahombekombe eYenisei kwemwedzi yakati wandei (Chivabvu-Chikumi 2019). Mvura yezhizha ndiyo nguva yakaoma kwazvo kune millimeter-wave radio communications, nekuti... madonhwe emvura anofananidzwa newavelength (anenge 4 mm), izvo zvinokonzera kupera simba kwechiratidzo. Muchando dambudziko iri hariitike, nekuti... mazaya echando, pamwe nemhute nehutsi, iredhiyo inoonekera kune isina waya yekutaurirana mu70/80 GHz renji.
Iyo 10 Gbit/s redhiyo bhiriji kubva kuDOK LLC yakatarisana nemamiriro ekunze uye chinhambwe, mushure mezvo, zvichibva pahuwandu hwekuwanikwa kwetambo yekutaurirana, mutyairi weUnity akasarudza kuyera kuita 4 parallel wireless channels ine simba re10GE imwe neimwe. Kuiswa kwacho kwakaitwa nenyanzvi kubva kukambani yeEdinstvo, avo vakazvimiririra vakafunga kuomarara kweiyo setup maererano nemirairo yemidziyo. Pakupera kwaChikunguru 2019, bhiriji redhiyo
40 Gbit / s (4x 10 Gbit / s) kuburikidza neYenisei yakagamuchirwa kuti ishandiswe mune zvekutengeserana pamberi peboka rekutarisa rekuisa kubva kukambani yeDOK.
