Apo makore matatu apfuura takazviita memori makadhi ekushandiswa kwemaindasitiri, mune zvakataurwa pakanga paine zvishuwo zvekusataura nezve drones nemakamera - vanoti, iyi haisi nzvimbo yakajairwa yekunyorera makadhi ekurangarira akadaro. Zvakanaka, takazviudza uye takazvinyora pasi muchirongwa chemukati - gadzira chinyorwa nekesi kubva kuindasitiri. Asi, sezvazvinoitika, shure kwekuyerera kwezvinyorwa pamusoro pezvigadzirwa zvitsva zveKingston, chinhu ichi chakaramba chiri kumashure kwenguva yakareba, kusvikira zvave pano, paHabrΓ©, patakasangana. . Anga achishandisa makadhi aya kubva muna 2016, uye anoshandisa mazana awo. Nenzira, mune yayo 40-gigabit redhiyo zambuko mhiri Yenisei, iyo yakaunza wireless communication, memori makadhi akaiswa .

Mukutanga kwa2016, ndiko kuti, pakazoonekwa makadhi emakadhi eKingston indasitiri-giredhi kubva kuongororo yedu, kusvetuka kwepamusoro mukumhanya kweredhiyo redhiyo redhiyo kwaigadzirwa mumusika wekufonera. Chizvarwa chechipiri chenhepfenyuro yeredhiyo inomhanya 1 Gbit / s, inotonga muna 2010-2015, yaifanirwa kupfuudza baton kune yechitatu chizvarwa redhiyo link inokwanisa kushanda mugumi Gigabit Ethernet standard uye kutumira data nekumhanya kwegumi. Gbit/s.

Nenzira, kugadzira chiteshi cheredhiyo chine hunhu hwekutapurirana hwakafanana netambo yemaziso, zvingangoita zvinhu zvishoma zvaidiwa pasi rose: kusikwa kwechinhu chitsva chechinhu chekutaurirana pasina waya 10 Gigabit Ethernet (10GE) uye kugoverwa kwehuwandu hwehuwandu hwakakwana muhupamhi apo zvinokwanisika "kukodzera" 10 - gigabit data stream. Iyi chiyero yaive seti yemafrequency 71-76 / 81-86 GHz, iyo, neruoko rwakareruka rweAmerican regulator FCC, yakagoverwa muUSA muna 2008. Nenguva isipi uyu muenzaniso wakateverwa nevatongi munenge nyika dzese dzepasirese, kusanganisira Russia (iyo 71-76 / 81-86 GHz renji yakabvumidzwa neBazi rezvekutaurirana reRussian Federation kuti ishandiswe mahara kubvira 2010).
Muna 2016, maMMIC machipisi (microwave monolithic integrated circuits) aidiwa nevagadziri, anokwanisa kupa QAM 256 redhiyo modulation yedanho rekufambisa data regumi Gbit/s, rakazobuda pamusika wepasi rose, uye nhangemutange yakatanga kuona kuti ndiani aizouya. iva wekutanga kuburitsa sampuli dzekutengesa dzekirasi relay michina pamusika 10GE. Zvinotoshamisa ndezvokuti, yekutanga yekugadzira sampuli yezvibatanidza zveredhiyo zvakagadzirwa muRussia kuSt. Petersburg engineering company DOK uye yakaratidzwa paMobile World Congress (MWC 10) muBarcelona mu2017. Zvakanaka, nei? - shure kwezvose, Alexander Popov akagadzira redhiyo muSt.
Nhasi, muna 2019, 10GE maredhiyo asina waya ave iyo de facto indasitiri chiyero. Nekuda kwekubuda kwayo kwepamusoro, imwe 10 Gbit/s redhiyo relay tambo inowanzo shanda nharaunda yese yekugara kana nzvimbo huru yemaindasitiri ine zvekutaurirana. Veserura vanoshandisa nokuzvidira 10GE redhiyo links kumusana pakati pe4G/LTE base zviteshi, nekuti ivo vanoonesa kuwiriraniswa kwezviteshi zvepasi nereferensi wachi yenharembozha yedata data, iyo yakakosha pakufambisa multimedia traffic kune smartphones uye mahwendefa. Pamusoro pekufona kwedhijitari uye kuwanikwa kweInternet, mazana emadhijitari eTV anotepfenyurwa kuburikidza ne10 Gigabit Ethernet isina waya chiteshi, uye kune rwizi rwe data kubva kuCCTV kamera.
"Izvi zvese zvinonakidza nenzira yazvo," muverengi waHabr achadaro, "asi makadhi ememori eKingston ane chekuita nazvo?" Asi izvi ndizvo zvatichaenderera mberi.
"Black bhokisi" mukati redhiyo relay michina
Kadhi rekurangarira yakaiswa mune yekudzora module yePPC-10G nhepfenyuro yeredhiyo inogadzirwa neDOK senge faira rekuchengetedza mafaera ekugadzirisa uye kutema kwemamiriro emidziyo. Ese akakosha maparamendi ekushanda anonyorerwa kadhi kutenderera wachi: dhata yekuchinjisa chiyero muchiteshi, yakagamuchirwa chiratidzo chenhanho (RSL, Gamuchira Chiratidzo Chiyero), tembiricha mune iyo kesi, magetsi ekupa paramita uye zvimwe zvakawanda. Zvinoenderana nemirairo yemugadziri, kadhi inofanirwa kuchengetedza data rakadaro kweinenge gore rekushandisa midziyo, ipapo iyo data nyowani inonyorwa pamusoro pekare. Kudzidzira kwakaratidza kuti kutevedzera zvinodiwa izvi, kadhi memori ye8 GB yakakwana, saka DOK ikozvino inoshandisa makadhi akadaro. Seti yezviteshi zviviri zveredhiyo zvinoda maviri Industrial Temperature microSD UHS-I memori makadhi, nekuti kadhi rinoiswa mune chimwe nechimwe chazvo.

Injiniya wetiweki kana maneja wenharembozha nguva nenguva anorodha matanda kubva kumemori kadhi kuburikidza neFTP kana kuaona muwebhu interface. Nenzira iyi, huwandu hwehuwandu hwechiteshi uye kugadzikana kwezvinhu zvemukati zveredhiyo relay zviteshi zvinoongororwa. Ruzivo kubva kumatanda inonyanya kukosha kana paine kutadza kwemidziyo kana shanduko yayo kune yakaderedzwa dhata rekufambisa.
Uchishandisa ruzivo kubva mumatanda anopihwa nemutengi, DOC tekinoroji yekutsigira nyanzvi inogona kuongorora dambudziko uye kupa zano rekukurumidza nzira yekurigadzirisa. Semuenzaniso, taona kuti chiyero chechiratidzo chakagamuchirwa (RSL) chachinja kubva pane imwe nguva, tinogona kugumisa kuti, kazhinji, kunongedza kweantenna kune mumwe nemumwe "kwakanganisa". Izvi dzimwe nguva zvinoitika mushure mechamupupuri-simba remhepo kana chando ichiwira pane antenna kubva kumusoro zvimiro zvenhare yenhare.
Vafambisi veTelecom, pavanenge vachitenga zvinodhura 10-gigabit relay relay michina, vimba nekuvimbika kwepamusoro kwezvinhu zvayo zvese zvinoenderana neiyo "seta uye uikanganwa". Memory card haina kusiyana apa. Chinhu chakakosha pano ndiko kuoma kwekuwana michina yekugadzira basa. Muhuwandu hwakawandisa hwemakesi, maredhiyo anongedzo mu71-76 / 81-86 GHz renji akaiswa panhare dzenhare, pamatenga ezvivakwa uye zvimiro. Zviri pachena kuti kukwira shongwe yechando munguva yechando yeRussia kutsiva zvikamu haisi basa riri nyore uye rine ngozi. Kunyangwe iyo memori kadhi isiri chikamu chakakosha muPPC-10G zviteshi, uye kana ikatadza, redhiyo relay mutsara icharamba ichishanda, asi kugona kurekodha michina uye yekukurukurirana chiteshi matanda anorasika. Nokudaro, kushanda kwakavimbika kwemakadhi kwakakosha kune mugadziri weredhiyo zvinongedzo uye kune vatengi vanomiririrwa nevanoshandisa telecom.

Maitiro ekunzvenga tembiricha miganhu yememory makadhi uye zvimwe zvinhu
Kana iwe ukatarisa peji ne Industrial Temperature microSD UHS-I memori makadhi, unogona kuona miganhu yavo yakavimbiswa kushanda uye kuchengetedza tembiricha renji: kubva -40Β°C kusvika +85Β°C. Asi chii chaunofanira kuita kana nhepfenyuro yeredhiyo inoshandiswa muRussia Arctic, apo usiku inogona kuva -50 Β° C kana kunyange pasi? Kana, zvakasiyana, kumwe kuAfrica?
