Daim ntawv thov raug ntawm 5G fronthaul raug qhia hauv daim duab, suav nrog kev sib txuas fiber ntau, passer WDM, thiab nquag siv WDM / optical thauj network (OTN) / slicing pob ntawv network (SPN).
Cov teeb meem txuas ncaj qha ntawm fiber ntau feem ntau siv 25 Gb / s grey lub teeb sib txuas, uas txhawb nqa ob hom fiber ntau thiab ib leeg-fiber ntau ob txoj kev, feem ntau suav nrog ob kis sib nrug ntawm 300m thiab 10km.
Cov xwm txheej Passive WDM feem ntau suav nrog taw-rau-taw qhia passive WDM thiab WDM-PON , thiab lwm yam, siv ib khub lossis ib lub fiber ua kom tiav qhov kev sib txuas ntawm ntau lub AAUs thiab DUs, feem ntau xav tau 10Gb / s lossis 25Gb / s xim kho qhov muag xim.
Nyob rau hauv kev siv WDM / OTN , 10Gb / s lossis 25Gb / s luv-ntau grey-teeb modules feem ntau xav tau ntawm AAU / DU rau WDM / OTN / SPN cov cuab yeej, thiab N × 10/25 / 50Gb / s yog qhov yuav tsum tau ntawm WDM / OTN / SPN cov khoom. / 100Gb / s ob chav ceev bi-directional lossis ib leeg fiber ntau bi-directional optical module ntawm tus nqi.
Feem ntau yuav tsum tau ua rau cov kho qhov muag teeb pom kev zoo hauv 5G fronthaul thov daim ntawv thov muaj raws li nram no:
(1) Tau raws li cov kev lag luam qhov ntsuas kub thiab muaj kev ntseeg siab: Xav txog AAU tag nrho cov chaw sab nraum zoov daim ntawv thov, qhov khoos phis tawm pem hauv ntej yuav tsum ua kom tau raws li cov khoom lag luam kub ntawm -40 ° C txog + 85 ° C, thiab yuav tsum muaj plua plav.
(2) Tus nqi qis: Qhov xav tau tag nrho rau 5G optical module xav kom dhau 4G. Hauv tshwj xeeb, cov khoos phis tawj pem hauv ntej kawg yuav muaj kaum tawm lab tus neeg thov. Tus nqi qis yog ib qho ntawm cov kev xav tau loj ntawm kev lag luam rau cov khoos phis tawm.
Hauv 5G, backhaul npog nrog cov xov nkag txheej, convergence txheej thiab tub ntxhais txheej. Qhov tsim nyog kho qhov muag hluav taws xob tsis txawv ntau ntawm cov tau siv hauv cov xaib thiab cov chaw zov me nyuam uas twb muaj lawm.
Kev nkag mus txheej yuav siv 25Gb / s, 50Gb / s, 100Gb / s thiab lwm lub teeb grey lossis xim teeb pom kev zoo,
kev sib koom ua ke txheej thiab sab saud feem ntau yuav siv DWDM xim teeb lub teeb nrog 100Gb / s, 200Gb / s, 400Gb / s thiab lwm yam nrawm.
Cov ntaub ntawv twg cov nqi kho qhov muag module siv hauv lub fronthaul?
25Gb / s thiab 100Gb / s, thiab txhawb nqa qhov kis tau tus mob siv txij li pua pua meters txog 20km. Cov xwm txheej tshwj xeeb hauv kev qhia hauv qab daim duab no.
* 1: Txais 10Gb / s industrial qib FP lossis DFB laser
* 2: Qhov chaw nruab nrab ntawm CWDM ua haujlwm nthwv cua yog 1271nm, 1291mm, 1311nm thiab 1331nm feem.
* 3: Raws li cov peev nyiaj txuas, kho qhov cuab lub zog loj thiab cov tsim kev cuam tshuam tuaj yeem tsim teeb meem;
* 4: DWDM ua haujlwm nthwv dej ua tau raws li ITU-tg694.1 kev siv lub yoj yoj
* 5: Qhov chaw nruab nrab ntawm plaub qhov kev ua haujlwm wavelengths ntawm 4wdm10 yog 1271mm, 1291mm, 1311nm thiab 1331nm feem.
Cov ntaub ntawv dab tsi tus nqi kho qhov muag module siv nyob rau hauv 5G rov qab?
Feem ntau suav 25Gb / s, 50Gb / s, 100Gb / s, 200Gb / s, 400Gb / s thiab lwm yam nrawm.
Kev sib kis tau sib txawv nyob ntawm ob peb kis mus txog ntau pua kis lus mev, txhawb CPRI, eCPRI, Ethernet, OTN thiab lwm yam kev cai sib txuas lus, ntxiv rau NRZ, PAM4, DMT thiab lwm hom kev hloov kho, cov xwm txheej tshwj xeeb qhia tau pom nyob hauv daim duab hauv qab no.
