5G kutumirwa kwe optical module application
5th Generation Mobile Communication Tekinoroji yakapfupikiswa se5G, chizvarwa chitsva chebroadband mobile communication tekinoroji ine hunhu hwekumhanya kwakanyanya, kuderera latency, uye yakakura yekubatanidza. 5G yekutaurirana zvivakwa ndiyo network network yekuwana vanhu-muchina uye chinhu chinobatana.
Iyo International Telecommunication Union (ITU) inotsanangura matatu makuru ekushandisa e5G, anoti Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (urRLLC), uye yakakura Machine Type yeKutaurirana (mMTC). eMBB inonyanya kutarisana nekukura kwekuputika kwefoni yeInternet traffic, ichipa ruzivo rwakanyanyisa rwekushandisa kune vashandisi veIndaneti; uRLLC inonyanya kunangwa kune vertical industry applications senge maindasitiri control, telemedicine, uye autonomous kutyaira, izvo zvine zvakanyanyisa zvinodiwa zvekunonoka uye kuvimbika; mMTC inonyanya kunangwa pamashandisirwo akadai semaguta akangwara, dzimba dzakangwara, uye kutarisa kwezvakatipoteredza kunonangana nekunzwa uye kuunganidza data.
Nekuenderera mberi kwekuenderera mberi kwesainzi uye tekinoroji, 5G network yave imwe yemisoro inopisa mundima yanhasi yekutaurirana. 5G tekinoroji haizongotipa nekukurumidza kufambisa data, asiwo inotsigira hukama hwakawanda pakati pemidziyo, nekudaro ichigadzira mikana yakawanda yemaguta akangwara emangwana, mota dzinozvimiririra uye Internet yezvinhu. Nekudaro, kuseri kweiyo 5G network, kune akawanda akakosha matekinoroji uye tsigiro yemidziyo, imwe yacho iri optical module.
Iyo optical module ndiyo yepakati chikamu che optical communication, iyo inonyanya kupedzisa iyo photoelectric kutendeuka, iyo yekupedzisira inotumira inoshandura chiratidzo chemagetsi muchiratidzo chemagetsi, uye kuguma kwekugamuchira kunoshandura chiratidzo chemagetsi muchiratidzo chemagetsi. Seyo musimboti mudziyo, optical module inoshandiswa zvakanyanya mumidziyo yekutaurirana uye ndiyo kiyi yekuona yakakwira bandwidth, kunonoka kunonoka uye kubatana kwakafara kwe5G.
Base station yekubatanidza: 5G base zviteshi zvinowanzowanikwa muzvivakwa zvepamusoro-soro, nhare dzenhare, nedzimwe nzvimbo, uye dzinoda kukurumidza uye nekuvimbika kutumira data kumidziyo yemushandisi. Optical modules inogona kupa yakakwira-kumhanya uye yakaderera latency data kutapurirana, kuve nechokwadi chekuti vashandisi vanogona kuwana emhando yepamusoro yekutaurirana masevhisi.
Data center connectivity: Nzvimbo dze data dzinogona kuchengeta uye kugadzirisa huwandu hukuru hwe data kuti isangane nezvinodiwa nemushandisi. Optical modules anoshandiswa kubatanidza pakati penzvimbo dzakasiyana dze data, pamwe nepakati penzvimbo dzedata uye zviteshi zvepasi, kuve nechokwadi chekuti data inogona kuendeswa nekukurumidza uye nemazvo.
Humiro hwese hwematanho ekutaurirana evafambisi venhare kazhinji hunosanganisira backbone network uye metropolitan area network. Iyo backbone network ndiyo yepakati network yeanoshanda, uye metropolitan nharaunda network inogona kukamurwa kuita musimboti layer, aggregation layer, uye yekuwana layer. Telecom vanoshanda vanovaka nhamba huru yezviteshi zvekutaurirana munzvimbo yekupinda, inovhara masaini etiweki kunzvimbo dzakasiyana siyana, zvichibvumira vashandisi kuwana network. Panguva imwecheteyo, zviteshi zvekutaurirana zvinoendesa data remushandisi kumusana wetiweki yevafambisi venhare kuburikidza nemetropolitan aggregation layer uye core layer network.
Kuti zvizadzise zvinodiwa nepamusoro bandwidth, low latency, uye kuvharika kwakafara, iyo 5G wireless access network (RAN) architecture yakabva kune maviri-level chimiro che4G baseband processing unit (BBU) uye redhiyo frequency pull-out unit ( RRU) kune matatu-nhanho chimiro chepakati unit (CU), yakagoverwa unit (DU), uye inoshanda antenna unit (AAU). Iyo 5G base station midziyo inobatanidza yekutanga RRU midziyo uye antenna midziyo ye4G mune itsva AAU midziyo, uku ichitsemura midziyo yekutanga yeBBU ye4G muDU neCU midziyo. Mune 5G inotakura network, iyo AAU neDU zvishandiso zvinogadzira kuendesa mberi, iyo DU uye CU zvishandiso zvinogadzira yepakati kutapurirana, uye iyo CU nemusana network inoumba backhaul.
Iyo nhatu-nhanho yekuvakisa inoshandiswa ne5G base station inowedzera dhizaini ye optical transmission link kana ichienzaniswa neyechipiri-level architecture ye4G base stations, uye nhamba ye optical ports inowedzera, saka kudiwa kwe optical modules kunowedzerawo.
1. Metro Access Layer:
Iyo metro yekupinda layer, iyo optical module inoshandiswa kubatanidza 5G base zviteshi uye kutapurirana network, inotsigira yakakwirira-kumhanyisa data kutakurwa uye yakaderera-latency kutaurirana. Mamiriro ekushandisa akajairika anosanganisira optical fiber yakananga kubatana uye passive WDM.
2. Metropolitan Convergence layer:
Pane metropolitan convergence layer, optical modules anoshandiswa kuunganidza data traffic pane akawanda mafungu ekupinda kuti ape yakakwirira-bandwidth uye yakakwirira-yakavimbika kufambisa data. Inoda kutsigira mazinga ekutapurirana akakwira uye kuvharika, senge 100Gb/s, 200Gb/s, 400Gb/s, nezvimwe.
3. Metropolitan core layer/Provincial Trunk Line:
In core layer uye trunk line transmission, optical modules inobata mabasa makuru ekutumira data, inoda kukurumidza kukuru, kuendesa kure-kure uye simba rekugadzira modulation teknolojia, yakadai seDWDM optical modules.
1. Kuwedzera kwehuwandu hwekutapurirana:
Nekuda kwepamusoro-speed ye5G network, mazinga ekutumira optical modules anoda kusvika kumazinga e25Gb / s, 50Gb / s, 100Gb / s kana kunyange yakakwirira kuti asangane nezvinodiwa zvekufambisa kwepamusoro-soro.
2. Chinja kune akasiyana mashandisirwo mamiriro:
Iyo optical module inoda kuita basa munzvimbo dzakasiyana dzekushandisa, zvinosanganisira indoor base station, yekunze base zviteshi, nzvimbo dzemadhorobha, nezvimwe, uye zvakatipoteredza zvakaita seye tembiricha, kudzivirira guruva uye kudzivirira mvura kunoda kutariswa.
3. Mutengo wakaderera uye kushanda kwakanyanya:
Kuendeswa kwakakura kwe5G network kunokonzeresa kudiwa kukuru kwemaoptical modules, saka mutengo wakaderera uye kushanda kwakanyanya ndizvo zvakakosha zvinodiwa. Kuburikidza nehunyanzvi hwekuvandudza tekinoroji uye kugadzirisa maitiro, mutengo wekugadzira weOptical module unoderedzwa, uye kugona kwekugadzira uye kugona kunovandudzwa.
4. Kuvimbika kwakakwirira uye maindasitiri giredhi tembiricha renji:
Iwo optical modules mu5G anotakura network anofanirwa kuve nekuvimbika kwakanyanya uye kukwanisa kushanda zvakatsiga muhushasha hwekushisa kwemaindasitiri (-40 ℃ kusvika + 85 ℃) kuti ienderane neyakasiyana nharaunda yekutumirwa uye mamiriro ekushandisa.
5. Optical performance optimization:
Iyo optical module inoda kukwidziridza kuita kwayo kwemaziso kuti ive nechokwadi chekufambisa kwakadzikama uye kugamuchirwa kwepamusoro-soro kwezviratidzo zvemaziso, kusanganisira kuvandudzwa kwekurasikirwa kwemaziso, kugadzikana kwewavelength, modulation tekinoroji, uye zvimwe zvinhu.
Mupepa iri, maoptical modules anoshandiswa mu5G kumberi, epakati uye ekumashure maapplication anounzwa zvakarongeka. Iwo optical modules anoshandiswa mu5G mberi, yepakati uye backpass zvikumbiro zvinopa vashandisi vekupedzisira sarudzo yakanakisa yekukurumidza, kunonoka kunonoka, kuderera kwesimba uye mutengo wakaderera. Mune 5G mutakuri network, optical modules, sechikamu chakakosha chezvivakwa, tora yakakosha kutumira data uye kutaurirana mabasa. Nekuzivikanwa uye kuvandudzwa kwe5G network, optical modules icharamba ichitarisana nepamusoro pekuita zvinodiwa uye matambudziko ekushandisa, zvinoda kuenderera mberi hunyanzvi uye kufambira mberi kuzadzisa zvinodikanwa zvenguva yemberi yekutaurirana network.
Pamwe chete nekukurumidza kusimudzira kwe5G network, optical module tekinoroji iri kuramba ichifambira mberi. Ini ndinotenda kuti ramangwana optical modules richava diki, rakanyanya kushanda, uye richikwanisa kutsigira yakakwirira data yekumhanyisa kumhanya. Inogona kusangana nekukura kuri kudiwa kwe5G network uku ichideredza kushandiswa kwesimba uye kuderedza kukanganiswa kwemanetiweki ekutaurirana pane zvakatipoteredza. Senyanzvi optical module mutengesi,kambaniichasimudzira humwe hutsva mu optical module tekinoroji uye kushanda pamwechete kupa rutsigiro rwakasimba rwekubudirira uye kusimudzira kusimudzira kwe5G network.
