Uphuhliso lwemodyuli yonxibelelwano olungenazingcingo: Inethiwekhi ye-5G, i-25G / 100G imodyuli ebonakalayo yindlela.
Ekuqaleni kwe-2000, iinethiwekhi ze-2G kunye ne-2.5G zaziphantsi kokwakhiwa.Uxhulumaniso lwesikhululo sesiseko saqala ukusika kwikhebula lobhedu ukuya kwikhebula le-optical cable.Imodyuli ye-1.25G ye-SFP ye-optical isetyenziswe ekuqaleni, kwaye imodyuli ye-2.5G ye-SFP isetyenziswe kamva.
Inethiwekhi ye-3G ye-2008-2009 yaqala ukwakhiwa, kwaye imfuno yeemodyuli ze-base station optical yaxhuma kwi-6G.
Kwi-2011, ihlabathi langena kulwakhiwo lwenethiwekhi ye-4G, kwaye i-predecessor ikakhulu isebenzisa iimodyuli ze-10G ze-optical.
Emva kwe-2017, ngokuthe ngcembe iguqukela kwinethiwekhi ye-5G, igxuma kwimodyuli ye-25G / 100G ye-optical.Inethiwekhi ye-4.5G (i-ZTE ebizwa ngokuba yi-Pre5G) isebenzisa imodyuli efanayo ye-optical njenge-5G.
Ukuthelekiswa kwe-5G ye-network architecture kunye ne-4G ye-architecture yenethiwekhi: Ngexesha le-5G, ukunyuka kokupasa okuphakathi kulindeleke ukuba kwandiswe imfuno yeemodyuli ze-optical.
Inethiwekhi ye-4G isuka kwi-RRU ukuya kwi-BBU ukuya kwigumbi eliphambili lekhompyutha.Ngexesha lenethiwekhi ye-5G, umsebenzi we-BBU unokuhlukana kwaye uhlukaniswe kwi-DU kunye ne-CU.I-RRU yasekuqaleni ukuya kwi-BBU yeye-prequel, i-BBU kwigumbi eliphambili lekhompyutheni liyimbuyekezo, kwaye i-5G yongeza ukudlula okuphakathi.
Indlela yokwahlula i-BBU inempembelelo enkulu kwimodyuli ye-optical.I-3G ngumenzi wezixhobo zasekhaya ezinezikhewu ezithile kwiimarike zamazwe ngamazwe, ixesha le-4G kunye ne-Qiping yangaphandle, ixesha le-5G laqala ukukhokela.Kutsha nje, i-Verizon kunye ne-AT & T ibhengeze ukuba baya kuqalisa i-5G yorhwebo kwiminyaka eyi-19, unyaka omnye ngaphambi kweChina.Ngaphambi koko, ishishini lalikholelwa ukuba ababoneleli abaqhelekileyo baya kuba ngabakwaNokia Ericsson, kwaye ekugqibeleni uVerizon wakhetha i-Samsung.Isicwangciso esipheleleyo sokwakhiwa kwe-5G yasekhaya yomelele, kwaye kungcono ukuqikelela ezinye.Namhlanje, igxile kakhulu kwimarike yaseTshayina.
Imodyuli ye-5G yangaphambili yokudluliselwa: Ixabiso le-100G liphezulu, okwangoku i-25G iyona nto iphambili
I-25G yangaphambili kunye ne-100G iya kuhlala kunye.I-interface phakathi kwe-BBU kunye ne-RRU kwixesha le-4G yi-CPRI.Ukuze ukwazi ukujamelana nemfuno ephezulu ye-bandwidth ye-5G, i-3GPP iphakamisa ujongano olutsha oluqhelekileyo lwe-eCPRI.Ukuba i-interface ye-eCPRI yamkelwe, imfuno ye-bandwidth ye-interface ye-preamble interface iya kuxinzelelwa kwi-25G, ngaloo ndlela inciphisa ukukhanya.Iindleko zothumelo.
Ngokuqinisekileyo, ukusetyenziswa kwe-25G kuya kuzisa iingxaki ezininzi.Eminye imisebenzi ye-BBU kufuneka ihanjiswe phezulu kwi-AAU ukwenza isampulu yomqondiso kunye noxinzelelo, ukuze i-AAU ibe nzima kwaye ibe nkulu.I-AAU ixhonywe kwinqaba, eneendleko eziphezulu zokulondolozwa kunye nomngcipheko womgangatho ongcono.Abakhulu, abathengisi bezixhobo baye basebenza ukunciphisa i-AAU kunye nokusetyenziswa kwamandla, ngoko ke kukwaqwalasela isisombululo se-100G, ukunciphisa umthwalo we-AAU.Ukuba ixabiso leemodyuli ze-100G ze-optical zingancitshiswa ngokufanelekileyo, abathengisi bezixhobo baya kukhetha izisombululo ze-100G.
Ukuhanjiswa kwe-5G: umehluko omkhulu phakathi kweenketho zemodyuli ye-optical kunye neemfuno zobuninzi
Abasebenzisi abohlukeneyo baneendlela ezahlukeneyo zothungelwano.Ngaphantsi kwenethiwekhi eyahlukeneyo, ukhetho kunye nobuninzi beemodyuli ze-optical ziya kwahluka kakhulu.Abathengi baye baphakamisa imfuno ye-50G, kwaye siya kusabela ngenkuthalo kwiimfuno zabathengi.
Ukubuya kwe-5G: imodyuli ye-optical ehambelanayo
I-backhaul iya kusebenzisa imodyuli ye-optical ehambelanayo kunye ne-interface bandwidth ye-100G.Kulindeleke ukuba ukuhambelana kwe-200G kuya kubala i-2 / 3 kunye ne-400G yokubambisana iya kuphendula kwi-1 / 3.Ukususela kwipaseji yangaphambili ukuya kwipaseji ephakathi ukuya kwi-back pass, ukudibanisa kwinqanaba, ukubuyiswa kokusetyenziswa kwemodyuli ye-optical kuncinci, kodwa ixabiso leyunithi liphezulu, ukusuka kwisixa semali kunye nokulingana.
Ukuvela kwepateni yokhuphiswano lwemizi-mveliso: iminyaka emithathu ezayo lixesha lokwanda kokhuphiswano
Ukuthunyelwa kweemodyuli ezinkulu ze-4G kuya kuhlala ixesha elide, kodwa ixabiso leyunithi liphantsi kakhulu.Le marike iphuhliswe iminyaka emininzi, kwaye indawo yentengiso iyonke ayinkulu kakhulu.
Ababoneleli bemodyuli ye-4G yehlabathi jikelele ngabavelisi basekhaya.AbakwaNokia kunye no-Ericsson nabo bathenga ikakhulu abavelisi basekhaya.Xa iimodyuli ze-4G ze-optical ziqala ukukhuphisana, abavelisi abaninzi bangaphandle bathatha inxaxheba, njengeFinisar kunye ne-Oclaro, kwaye bakhuphisane kunyaka wesithathu.Ngokusisiseko, irhoxile, ishiya kuphela abavelisi baseTshayina, abanjengoHisense, iGuangxun, kunye noHuagong Zhengyuan (iSurcer nayo inazo).
I-5G isiseko semodyuli ye-optical station, kukho ngoku malunga ne-5 okanye i-6 iisampulu kwiisampuli zabathengi.Kulindeleke ukuba kubekho iinkampani ezininzi eziza kuthatha inxaxheba kuyo.Kwi-2018, uvavanyo lwesampula luya kufikelela malunga ne-10, kodwa umthengi akanalo izixhobo ezaneleyo zokulinganisa ezininzi.Imveliso nganye ivavanywa ngokwethiyori ezintlanu, kwaye ezintathu zazo ziye zadlula umngcipheko wokuhanjiswa.Inani eliphezulu lezatifiketi ukuya ezintlanu ligcwele kakhulu, ngoko i-10 kwi-2018 kulindeleke ukuba isuse i-5 eseleyo, kwaye ezi zi-5 zenziwa ngo-2019. Uhlanga lokuqala, umgangatho, ukuhanjiswa kunye nokulawulwa kweendleko, kuqikelelwa ukuba emva kwe-2019, kukho. iya kuba malunga ne-3 enkulu yababoneleli abashiyekileyo, i-2018-2019 iya kuba yinqanaba elibukhali kakhulu le-5G ye-optical module market screening, kwaye iphethini yemarike iya kuzinza emva kwe-2019.
