Kuvandudzwa kwewireless optical communication module: 5G network, 25G/100G optical module ndiyo maitiro.
Pakutanga kwa2000, iyo 2G uye 2.5G network yaive ichivakwa.Iyo base station yekubatanidza yakatanga kucheka kubva patambo yemhangura kuenda kune yekuona tambo.Iyo 1.25G SFP optical module yakashandiswa pakutanga, uye 2.5G SFP module yakashandiswa gare gare.
Iyo 2008-2009 3G network yakatanga kuvakwa, uye kudiwa kwe base station optical modules kwakasvetukira ku6G.
Muna 2011, nyika yakapinda mukuvaka 4G network, uye yakatangira yainyanya kushandisa 10G optical modules.
Mushure me2017, zvishoma nezvishoma inoshanduka kune 5G network, ichisvetuka kune 25G / 100G optical module.Iyo 4.5G network (ZTE inonzi Pre5G) inoshandisa imwechete optical module se5G.
Kuenzanisa kwe5G network architecture uye 4G network architecture: Munguva ye5G, kuwedzera kwekupfuura kwepakati kunotarisirwa kuwedzera kudiwa kwemaoptical modules.
Iyo 4G network inobva kuRRU kuenda kuBBU kuenda kukamuri yekombuta yepakati.Munguva ye5G network, basa reBBU rinogona kupatsanurwa uye rakakamurwa kuva DU uye CU. RRU yepakutanga kuBBU ndeye prequel, BBU kumakamuri makuru emakombiyuta ndeyekudzoka, uye 5G inowedzera kudarika kwepakati.
Maitiro ekuparadzanisa iyo BBU ine simba rakakura pane optical module.3G inyanzvi yekugadzira midziyo yemumba ine mamwe mapeji mumusika wepasi rose, nguva ye4G uye yekune dzimwe nyika Qiping, nguva ye5G yakatanga kutungamirira.Recently, Verizon uye AT & T vakazivisa kuti vachatanga kutengesa 5G mumakore 19, gore risati rapfuura China.Izvi zvisati zvaitika, indasitiri yaitenda kuti vatengesi vepamusoro vaizove Nokia Ericsson, uye pakupedzisira Verizon yakasarudza Samsung.Kurongeka kwese kwekuvaka kwe5G kwemba kwakasimba, uye zviri nani kufanotaura zvimwe.Nhasi, inonyanya kutarisa pamusika weChina.
5G pamberi pekutumira module: 100G mutengo wakakwirira, ikozvino 25G ndiyo inonyanya kukosha
Iyo yakatangira 25G uye 100G ichagara pamwe chete.Iyo interface pakati peBBU neRRU munguva ye4G ndeye CPRI.Kuti utsungirire iyo yakakwira bandwidth inodiwa ye5G, 3GPP inokurudzira hutsva hunoenderana chiyero eCPRI.Kana iyo eCPRI interface yakagamuchirwa, iyo bandwidth inodiwa ye preamble interface ichamanikidzwa ku25G, nokudaro kuderedza mwenje.Mari yekufambisa.
Zvechokwadi, kushandiswa kwe25G kuchaunza matambudziko akawanda.Mamwe mabasa eBBU anoda kukwidzwa kuenda kuAAU kuita chiratidzo sampling uye compression, kuitira kuti iyo AAU iwedzere kurema uye yakakura.Iyo AAU yakaturikwa pashongwe, iyo ine mutengo wepamusoro wekugadzirisa uye njodzi yemhando yepamusoro.Makuru, vatengesi vezvigadzirwa vave vachishanda kuderedza AAU uye kushandiswa kwesimba, saka iri kufungawo nezve 100G mhinduro, kuderedza mutoro weAAU.Kana mutengo we100G optical modules unogona kuderedzwa zvinobudirira, vatengesi vemidziyo vacharamba vachida 100G mhinduro.
5G kutapurirana: musiyano mukuru pakati pe optical module sarudzo uye huwandu hunodiwa
Vashandisi vakasiyana vane maitiro akasiyana etiweki.Pasi pekubatana kwakasiyana, kusarudzwa uye huwandu hwemamodule optical huchasiyana zvakanyanya.Vatengi vakasimudza kudiwa kwe50G, uye isu tichapindura nesimba kune zvinodiwa nevatengi.
5G kudzoka: coherent Optical module
Iyo backhaul ichashandisa coherent optical module ine interface bandwidth inopfuura 100G.Zvinotarisirwa kuti kuwirirana kwe200G kuchaverengera 2/3 uye 400G kuwirirana kuchazvidavirira 1/3.Kubva pane yakapfuura kuenda kune yepakati pass kuenda kumashure yekupfuura, iyo convergence yezinga, kudzoka kweiyo optical module kushandiswa kudiki, asi mutengo weyuniti wakakwira, kubva pamari uye yakaenzana.
Evolution yeindasitiri yemakwikwi maitiro: makore matatu anotevera inguva yekuwedzera makwikwi
Kutengeswa kwakakura kwe4G optical modules kuchagara kwenguva yakareba, asi mutengo weyuniti wakaderera zvikuru.Musika uyu wakagadzirwa kwemakore akati wandei, uye nzvimbo yese yemusika haina kunyanya kukura.
Iwo epasi rose 4G optical module vatengesi vanonyanya kugadzira epamba.Nokia uye Ericsson vanotengawo kunyanya vagadziri vepamba.Kana 4G optical modules ichangotanga kukwikwidza, vagadziri vakati wandei vekunze vanotora chikamu, seFinisar naOclaro, uye vanokwikwidza kwegore rechitatu.Chaizvoizvo, yasiya, ichisiya chete vagadziri veChinese, vakaita saHisense, Guangxun, naHuagong Zhengyuan (Muroyi anewo vamwe).
5G base station optical module, pari zvino pane angangoita mashanu kana matanhatu masampula evatengi samples.Zvinotarisirwa kuti kuchave nemakambani akati wandei achatora chikamu mariri.Muna 2018, bvunzo yemuenzaniso ichasvika gumi, asi mutengi haana zviwanikwa zvakakwana zvekuyera zvakawanda.Chigadzirwa chega chega chinoyedzwa mune zvishanu, uye vatatu vacho vakapfuura njodzi yekuburitsa.Kuwanda kwenhamba yezvitupa kune zvishanu kwakazara kwazvo, saka gumi muna 2018 inotarisirwa kubvisa 5 yasara, uye idzi 5 dzinoitwa muna 2019. Mujaho wekutanga, mhando, kuendesa uye kudzora mutengo, inofungidzirwa kuti mushure me2019, pane ichave inenge 3 vatengesi vakuru vasara, 2018-2019 ichave yakanyanya kusimba nhanho ye5G optical module yemusika kuongorora, uye musika pateni ichagadzikana mushure me2019.
