5G kev tsim kho yuav tsav qhov kev loj hlob sai ntawm kev thov rau optical modules rau kev sib txuas lus.Raws li 5G optical module yuav tsum, nws muab faib ua peb ntu: fronthaul, midhaul, thiab backhaul.
5G fronthaul: 25G / 100G optical module
5G tes hauj lwm xav tau ntau dua qhov chaw nres tsheb / cell site ceev, yog li qhov kev thov rau high-speed optical modules tau nce heev.25G / 100G optical modules yog cov kev daws teeb meem zoo tshaj plaws rau 5G fronthaul networks.Txij li thaum eCPRI (txhim kho cov pej xeem xov tooj cua interface) raws tu qauv interface (tus nqi raug yog 25.16Gb / s) yog siv los xa cov cim qhia ntawm 5G hauv paus chaw nres tsheb, 5G fronthaul network yuav vam khom rau 25G optical modules.Cov neeg ua haujlwm tau ua haujlwm hnyav los npaj cov txheej txheem thiab cov txheej txheem los pab txhawb kev hloov mus rau 5G.Thaum nws ncov, nyob rau hauv 2021, lub domestic 5G yuav tsum tau kho qhov muag module lag luam yuav tsum mus txog RMB 6.9 billion, nrog rau 25G optical modules accounting rau 76.2%.
Muab rau hauv tus account tag nrho cov sab nraum zoov daim ntawv thov ib puag ncig ntawm 5G AAU, 25G optical module siv nyob rau hauv lub fronthaul network yuav tsum tau ua kom tau raws li qhov muaj kub ntawm -40 ° C mus rau +85 ° C thiab dustproof yuav tsum, thiab 25G grey lub teeb thiab xim xim. modules yuav Deploy raws li qhov sib txawv fronthaul architectures siv nyob rau hauv 5G tes hauj lwm.
Lub 25G grey kho qhov muag module muaj ntau cov khoom siv kho qhov muag fiber ntau, yog li nws yog qhov tsim nyog rau optical fiber ntau point-to-point optical fiber ncaj qha kev twb kev txuas.Txawm hais tias txoj kev sib txuas ntawm optical fiber ntau yog qhov yooj yim thiab tus nqi qis, nws tsis tuaj yeem ua tau raws li kev tswj hwm kev ua haujlwm xws li kev tiv thaiv network thiab kev saib xyuas.Yog li ntawd, nws tsis tuaj yeem muab kev ntseeg siab rau uRLLC cov kev pabcuam thiab siv cov khoom siv kho qhov muag ntau dua.
25G xim kho qhov muag modules yog ntsia tau rau hauv passive WDM thiab nquag WDM / OTN tes hauj lwm, vim hais tias lawv tuaj yeem muab ntau yam kev sib txuas AAU rau DU siv ib qho fiber ntau.Cov tshuaj Passive WDM siv cov khoom siv fiber ntau tsawg, thiab cov khoom siv passive yog ib qho yooj yim los tswj, tab sis nws tseem tsis tuaj yeem ua tiav kev saib xyuas network, kev tiv thaiv, kev tswj hwm thiab lwm yam haujlwm;nquag WDM / OTN txuag cov peev txheej fiber ntau thiab tuaj yeem ua tiav OAM cov haujlwm xws li kev ua haujlwm siv nyiaj siv ua haujlwm thiab kuaj pom qhov tsis raug, thiab Muab kev tiv thaiv network.Cov thev naus laus zis no ib txwm muaj cov yam ntxwv ntawm cov bandwidth loj thiab qeeb qeeb, tab sis qhov tsis zoo yog tias tus nqi ntawm kev tsim kho network yog qhov siab.
100G optical modules kuj suav hais tias yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws rau fronthaul networks.Hauv 2019, 100G thiab 25G optical modules tau teeb tsa raws li cov qauv kev teeb tsa kom ua raws li kev loj hlob sai ntawm 5G kev lag luam thiab kev pabcuam.Hauv fronthaul tes hauj lwm uas xav tau kev ceev dua, 100G PAM4 FR / LR optical modules tuaj yeem xa mus.100G PAM4 FR/LR optical module tuaj yeem txhawb 2km (FR) lossis 20km (LR).
5G kis tau tus mob: 50G PAM4 optical module
5G mid-transmission network muaj cov cai rau 50Gbit / s optical modules, thiab ob qho tib si grey thiab xim optical modules tuaj yeem siv.50G PAM4 QSFP28 optical module siv LC optical chaw nres nkoj thiab ib hom fiber ntau tuaj yeem ua ob npaug ntawm bandwidth los ntawm ib hom fiber ntau txuas yam tsis tau txhim kho lub lim rau wavelength division multiplexing.Los ntawm kev sib koom DCM thiab BBU site amplification, 40km tuaj yeem kis tau.Qhov kev thov rau 50G optical modules feem ntau yog los ntawm kev tsim kho ntawm 5G bearer networks.Yog tias 5G cov tes hauj lwm tau txais kev pom zoo, nws txoj kev lag luam yuav tsum ncav cuag kaum lab.
5G backhaul: 100G / 200G / 400G optical module
5G backhaul network yuav tsum nqa tsheb ntau dua 4G vim tias muaj kev ua tau zoo dua thiab siab dua bandwidth 5G NR xov tooj cua tshiab.Yog li ntawd, cov txheej txheem kev sib tshuam thiab cov txheej txheem tseem ceeb ntawm 5G backhaul network muaj cov cai rau DWDM xim optical modules nrog ceev ntawm 100Gb / s, 200Gb / s, thiab 400Gb / s.Lub 100G PAM4 DWDM optical module feem ntau yog siv rau hauv cov txheej txheem nkag thiab txheej txheej, thiab tuaj yeem txhawb nqa 60km los ntawm kev sib koom T-DCM thiab optical amplifier.Cov tub ntxhais txheej kis tau tus mob yuav tsum muaj peev xwm thiab ncua deb ntawm 80km, yog li 100G / 200G / 400G coherent DWDM optical modules yuav tsum tau txhawb nqa metro tub ntxhais DWDM network.Tam sim no, qhov tseem ceeb tshaj plaws yog 5G network qhov kev thov rau 100G optical modules.Cov neeg muab kev pabcuam xav tau 200G thiab 400G bandwidth kom ua tiav qhov kev xav tau rau kev xa tawm 5G.
Nyob rau hauv nruab nrab-kis tau tus mob thiab backhaul scenarios, optical modules feem ntau siv nyob rau hauv lub computer chav nrog zoo cua sov dissipation tej yam kev mob, yog li coj mus muag-qib kho qhov muag modules yuav siv tau.Tam sim no, kev sib kis deb hauv qab 80km feem ntau siv 25Gb / s NRZ lossis 50Gb / s, 100 Gb / s, 200Gb / s, 400Gb / s PAM4 optical modules, thiab kev sib kis ntev tshaj 80km yuav tsuas yog siv cov khoom siv kho qhov muag sib txuas ( ib tus neeg nqa khoom 100 Gb / s thiab 400 Gb / s).
Hauv cov ntsiab lus, 5G tau txhawb txoj kev loj hlob ntawm 25G / 50G / 100G / 200G / 400G optical module lag luam.
