Kev loj hlob ntawm wireless optical kev sib txuas lus modules: 5G tes hauj lwm, 25G / 100G optical modules yog tus qauv
Thaum pib ntawm 2000, 2G thiab 2.5G tes hauj lwm tau tsim kho, thiab qhov chaw nres tsheb hauv paus kev sib txuas tau pib txiav los ntawm tooj liab cables rau optical cables.Thaum xub thawj, 1.25G SFP optical modules tau siv, thiab tom qab ntawd 2.5G SFP modules tau siv.
3G network kev tsim kho pib xyoo 2008-2009, thiab qhov kev thov rau qhov chaw nres tsheb kho qhov muag tau dhia mus rau 6G.
Nyob rau hauv 2011, lub ntiaj teb no nkag mus rau hauv kev tsim kho ntawm 4G tes hauj lwm, thiab lub ntsiab 10G optical modules siv nyob rau hauv lub prequel.
Tom qab xyoo 2017, nws tau maj mam hloov mus rau 5G tes hauj lwm thiab dhia mus rau 25G / 100G optical modules.Lub 4.5G network (ZTE hu Pre5G) siv tib lub optical modules li 5G.
Kev sib piv ntawm 5G network architecture thiab 4G network architecture: Hauv 5G era, nce qhov kis tau tus mob, nws xav tias qhov kev thov rau optical modules yuav nce.
Lub 4G network yog los ntawm RRU mus rau BBU mus rau chav tsev hauv computer.Hauv 5G network era, BBU cov haujlwm yuav raug muab faib ua DU thiab CU.Thawj RRU rau BBU belongs rau fronthaul, thiab BBU mus rau hauv lub computer tub ntxhais chav tsev belongs rau lub backhaul.Tawm ntawm qhov hla.
Yuav ua li cas BBU muab faib muaj kev cuam tshuam ntau dua rau qhov kho qhov muag module.Hauv 3G era, cov neeg muag khoom hauv tsev muaj qee qhov sib txawv nrog cov thoob ntiaj teb.Nyob rau hauv 4G era, lawv tau sib npaug nrog cov teb chaws txawv teb chaws, thiab 5G era tab tom 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 dhau los ntawm Tuam Tshoj.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 5G kev tsim kho hauv Suav teb 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 lub teeb kis tau tus mob module: 100G tus nqi yog siab, tam sim no 25G yog lub ntsiab
Ob qho tib si fronthaul 25G thiab 100G yuav ua ke.Lub interface ntawm BBU thiab RRU hauv 4G era yog CPRI.Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj bandwidth siab ntawm 5G, 3GPP tawm tswv yim tshiab interface tus qauv eCPRI.Yog tias siv eCPRI interface, qhov kev xav tau ntawm bandwidth ntawm fronthaul interface yuav raug compressed rau 25G, yog li txo cov nqi xa hluav taws xob kho qhov muag.Qhov tseeb, kev siv 25G kuj tseem yuav ua rau muaj teeb meem ntau.Nws yog ib qho tsim nyog yuav tsum tau txav qee qhov haujlwm ntawm BBU mus rau AAU rau cov teeb liab sampling thiab compression.Yog li ntawd, AAU ua hnyav dua thiab loj dua.AAU tau dai rau ntawm tus pej thuam, uas muaj cov nqi kho ntau dua thiab muaj kev pheej hmoo siab dua.Cov tuam txhab loj, cov cuab yeej siv tau ua haujlwm kom txo tau AAU thiab txo qis kev siv hluav taws xob, yog li lawv kuj tseem xav txog 100G cov kev daws teeb meem los txo lub nra ntawm AAU.Yog tias 100G optical module tus nqi tuaj yeem txo tau zoo, cov khoom lag luam tseem yuav nyiam 100G kev daws teeb meem.
5G Intermediate: Optical module xaiv thiab qhov xav tau kom muaj nuj nqis sib txawv heev
Cov neeg ua haujlwm sib txawv muaj txoj hauv kev sib txawv.Nyob rau hauv sib txawv networking, xaiv thiab tus naj npawb ntawm optical modules yuav txawv heev.Cov neeg siv khoom tau muab tso rau tom ntej 50G cov cai, thiab peb yuav nquag teb rau cov neeg siv khoom xav tau.
5G Backhaul: Coherent Optical Module
Lub backhaul yuav siv coherent optical modules nrog interface bandwidths tshaj 100G.Nws kwv yees tias 200G coherent account rau 2/3 thiab 400G coherent account rau 1/3.Los ntawm pem hauv ntej mus rau nruab nrab pass mus rau rov qab pass, nws converges step by step.Tus nqi ntawm cov khoom siv kho qhov muag siv rau kev hla rov qab yog me dua qhov kev hla dhau, tab sis tus nqi tsev yog siab dua.
Lub neej yav tom ntej: tej zaum yuav yog lub ntiaj teb ntawm chips
Lub ntuj zoo ntawm cov nti yuav ua rau nws ntau dua thiab tseem ceeb hauv lub module.Piv txwv li, MACOM tsis ntev los no tau tshaj tawm kev lag luam thawj zaug kev sib xyaw monolithic nti rau luv luv 100G optical transceivers, active optical cables (AOC) thiab on-board optical engines.Xa thiab txais cov kev daws teeb meem.Tus tshiab MALD-37845 seamlessly integrates plaub-channel xa thiab tau txais moos cov ntaub ntawv rov qab (CDR) functions, plaub transimpedance amplifiers (TIA), thiab plaub ntsug kab noj hniav nto emitting laser (VSCEL) tsav tsheb los muab cov neeg muas zaub nrog unparalleled yooj yim ntawm kev siv thiab tsis tshua muaj heev. nqi.
Tus tshiab MALD-37845 txhawb nqa cov ntaub ntawv tag nrho ntawm 24.3 txog 28.1 Gbps thiab yog tsim los rau CPRI, 100G Ethernet, 32G Fiber Channel, thiab 100G EDR unlimited bandwidth applications.Nws yuav muab cov neeg siv khoom nrog lub zog qis ib leeg-chip kev daws teeb meem thiab yog ib qho compact optical zoo tagnrho rau cov khoom siv.MALD-37845 txhawb kev sib koom tes nrog ntau yam VCSEL lasers thiab photodetectors, thiab nws cov firmware tau sib xws nrog cov kev daws teeb meem yav dhau los MACOM.
"Kev kho qhov muag module thiab AOC cov chaw muab kev pabcuam raug mob hnyav vim tias lawv xav tau los pab cov neeg siv khoom ua tiav 100G kev sib txuas loj," said Marek Tlalka, tus thawj coj lag luam loj ntawm cov khoom lag luam analog ua haujlwm siab ntawm MACOM."Peb ntseeg tias MALD-37845 tuaj yeem kov yeej kev sib koom ua ke thiab cov teeb meem ntawm tus nqi uas muaj nyob rau hauv cov khoom siv ntau lub nti thiab muab cov kev daws teeb meem zoo rau kev siv luv luv 100G."
MACOM's MALD-37845 100G ib leeg-chip tov tam sim no ua piv txwv rau cov neeg siv khoom thiab tau teem sijhawm pib tsim khoom hauv thawj ib nrab xyoo 2019.
