Kev loj hlob ntawm wireless optical kev sib txuas lus module: 5G network, 25G / 100G optical module yog tus qauv.
Thaum pib ntawm 2000, 2G thiab 2.5G tes hauj lwm tau tsim kho. Lub hauv paus chaw nres tsheb sib txuas pib txiav los ntawm tooj liab cable mus rau optical cable. 1.25G SFP optical module tau siv thaum pib, thiab 2.5G SFP module tau siv tom qab.
Xyoo 2008-2009 3G network pib tsim, thiab qhov kev thov rau lub hauv paus chaw nres tsheb optical modules dhia mus rau 6G.
Xyoo 2011, lub ntiaj teb tau nkag mus rau 4G network kev tsim kho, thiab cov thawj coj tau siv 10G optical modules.
Tom qab xyoo 2017, nws tau maj mam hloov mus rau 5G network, dhia mus rau 25G / 100G optical module. Lub 4.5G network (ZTE hu ua Pre5G) siv tib lub optical module li 5G.
Kev sib piv ntawm 5G network architecture thiab 4G network architecture: Nyob rau hauv 5G era, qhov nce hauv nruab nrab hla yuav tsum nce qhov kev thov rau optical modules.
Lub 4G network yog los ntawm RRU mus rau BBU mus rau chav tsev hauv computer. Nyob rau hauv 5G network era, BBU muaj nuj nqi yuav raug faib thiab muab faib ua DU thiab CU.Tus thawj RRU rau BBU belongs rau lub prequel, lub BBU mus rau lub core computer chav tsev belongs rau lub rov qab, thiab 5G ntxiv rau nruab nrab pass.
Yuav ua li cas faib BBU muaj kev cuam tshuam ntau dua ntawm qhov kho qhov muag module. 3G yog cov chaw tsim khoom siv hauv tsev nrog qee qhov sib txawv hauv kev ua lag luam thoob ntiaj teb, 4G era thiab txawv teb chaws Qiping, 5G era pib ua. Tsis ntev los no, Verizon thiab AT&T tshaj tawm tias lawv yuav pib ua lag luam 5G hauv 19 xyoo, ib xyoos ua ntej Suav teb. Ua ntej ntawd, kev lag luam ntseeg tias cov khoom lag luam tseem ceeb yuav yog Nokia Ericsson, thiab thaum kawg Verizon xaiv Samsung. Kev npaj tag nrho ntawm kev tsim kho hauv tsev 5G muaj zog dua, thiab nws yog qhov zoo dua los kwv yees qee qhov. Niaj hnub no, nws tsuas yog tsom mus rau Suav lag luam.
5G pem hauv ntej kis module: 100G tus nqi yog siab, tam sim no 25G yog lub ntsiab
Tus thawj ntawm 25G thiab 100G yuav ua ke. Lub interface ntawm BBU thiab RRU hauv 4G era yog CPRI. Txhawm rau tiv nrog qhov yuav tsum tau muaj bandwidth siab ntawm 5G, 3GPP tawm tswv yim tshiab interface tus qauv eCPRI. Yog tias eCPRI interface tau txais, qhov bandwidth yuav tsum tau ntawm lub preamble interface yuav raug compressed rau 25G, yog li txo lub teeb. Tus nqi kis tau tus mob.
Tau kawg, kev siv 25G yuav ua rau muaj teeb meem ntau. Qee qhov haujlwm ntawm BBU yuav tsum tau txav mus rau AAU los ua cov qauv ntsuas thiab compression, kom AAU ua hnyav thiab loj dua. Lub AAU tau dai rau ntawm tus pej thuam, uas muaj tus nqi saib xyuas ntau dua thiab muaj kev pheej hmoo zoo dua. Cov khoom loj, cov neeg muag khoom tau ua haujlwm kom txo tau AAU thiab kev siv hluav taws xob, yog li nws kuj tseem xav txog 100G kev daws teeb meem, txo lub nra ntawm AAU. Yog tias tus nqi ntawm 100G optical modules tuaj yeem txo tau zoo, cov neeg muag khoom yuav tseem nyiam 100G kev daws teeb meem.
5G kis tau tus mob: qhov sib txawv loj ntawm optical module xaiv thiab kom muaj nuj nqis
Cov neeg ua haujlwm sib txawv muaj ntau hom kev sib txuas. Raws li kev sib txuas sib txawv, kev xaiv thiab ntau ntawm cov khoom siv kho qhov muag yuav txawv heev. Cov neeg siv khoom tau tsa qhov kev thov ntawm 50G, thiab peb yuav nquag teb rau cov neeg siv khoom xav tau.
5G rov qab: coherent optical module
Lub backhaul yuav siv ib coherent optical module nrog ib tug interface bandwidth ntawm tshaj 100G. Nws cia siab tias 200G kev sib koom ua ke yuav suav rau 2/3 thiab 400G kev sib koom ua ke yuav suav rau 1/3. Los ntawm qhov dhau los dhau mus rau qhov nruab nrab dhau mus rau sab nraub qaum, qhov sib txuam ntawm theem, qhov rov qab los ntawm kev siv cov khoom siv kho qhov muag yog qhov me me, tab sis cov nqi tsev yog siab dua, los ntawm cov nyiaj thiab qhov sib npaug.
Evolution ntawm kev lag luam kev sib tw qauv: peb xyoos tom ntej no yog lub sijhawm ntawm kev sib tw nce ntxiv
Kev xa khoom loj ntawm 4G optical modules yuav kav ntev, tab sis tus nqi qis heev. Lub khw no tau tsim los rau ntau xyoo, thiab qhov chaw ua lag luam tag nrho tsis yog tshwj xeeb.
Lub ntiaj teb no 4G optical module cov chaw muag khoom yog cov tuam txhab tsim khoom hauv tsev. Nokia thiab Ericsson kuj tseem yuav cov tuam txhab tsim khoom hauv tsev. Thaum 4G optical modules nyuam qhuav pib sib tw, ntau lub tuam txhab txawv teb chaws koom nrog, xws li Finisar thiab Oclaro, thiab sib tw rau xyoo peb. Yeej, nws tau thim tawm, tsuas yog cov tuam txhab suav suav xwb, xws li Hisense, Guangxun, thiab Huagong Zhengyuan (Sorcer kuj muaj qee qhov).
5G hauv paus chaw nres tsheb kho qhov muag module, tam sim no muaj txog 5 lossis 6 tus qauv rau cov neeg siv khoom kuaj. Nws cia siab tias yuav muaj ntau lub tuam txhab koom nrog nws. Xyoo 2018, cov qauv ntsuas yuav ncav cuag li 10, tab sis cov neeg siv khoom tsis muaj peev txheej txaus los ntsuas ntau ntau. Txhua yam khoom yog kev sim theoretically hauv tsib, thiab peb ntawm lawv tau pib dhau qhov kev pheej hmoo ntawm kev xa khoom. Qhov siab tshaj plaws ntawm cov ntawv pov thawj rau tsib yog saturated heev, yog li 10 xyoo 2018 yuav tsum tshem tawm 5 qhov seem, thiab cov 5 no tau ua tiav hauv 2019. Kev sib tw thawj zaug, kev ua tau zoo, kev xa khoom thiab kev tswj tus nqi, kwv yees tias tom qab 2019, muaj yuav yog li ntawm 3 tus neeg muag khoom tseem ceeb sab laug, 2018-2019 yuav yog theem khaus tshaj plaws ntawm 5G optical module kev lag luam tshuaj xyuas, thiab cov qauv kev lag luam yuav ruaj khov tom qab 2019.
