Yuav ua li cas teeb tsa 100G lub nroog cheeb tsam network?
Nrog rau qhov nrov hauv Is Taws Nem, cov ntaub ntawv kev khiav tsheb ntawm lub nroog cheeb tsam network tau nce, thiab lub siab ntawm nws lub network bandwidth tau nce. Thawj 10G thiab 40G wavelength faib cov cuab yeej muaj peev xwm tau maj mam ua tsis tau raws li qhov yuav tsum tau muaj bandwidth siab. Kev siv 100G WDM cov cuab yeej tuaj yeem nqa tau ntau lub tsheb, uas yog qhov tsim nyog rau daim ntawv thov hauv cov chaw loj hauv nroog loj.
Qhov zoo ntawm 100G cheeb tsam cheeb tsam network yog pom tseeb
Nyob rau hauv ib txwm 10G thiab 40G cheeb tsam cheeb tsam network, cov neeg ua haujlwm xaiv cov tshuab lim dej ruaj khov lossis ROADM thev naus laus zis los siv cov khoom siv kho qhov muag. Passive filters muab tus nqi qis, yooj yim-rau-siv point-to-point kev sib txuas rau hauv cheeb tsam hauv cheeb tsam network, tab sis tsis muaj kev hloov pauv thiab scalability; ROADM-raws li cheeb tsam cheeb tsam network kev daws teeb meem yog ib qho yooj yim rau kev khiav lag luam thiab hloov tau, tab sis muaj cov nqi siab.
Tsis zoo li 10G thiab 40G cheeb tsam hauv cheeb tsam network, 100G cheeb tsam cheeb tsam network siv cov khoom siv kho qhov muag uas tau tsim kho tshiab uas hloov pauv tau thiab hloov tau raws li ROADM-based networks, tab sis tsis muaj qhov kim wavelength selective keyboards (WSS) thiab optical filter. Nrog kev pab los ntawm kev siv thev naus laus zis, 100G hauv nroog cheeb tsam network tuaj yeem txhawb nqa tsis yog kis mus rau taw tes xwb, tab sis kuj tseem kis mus rau ntau qhov chaw, ua rau lub network hloov pauv thiab yav tom ntej-pov thawj. Tsis tas li ntawd, 100G cheeb tsam cheeb tsam network muaj qhov zoo hauv qab no:
1. Lub peev xwm loj dua, tus nqi sib kis ntawm ib qho fiber ntau yog mus txog 100G kom tau raws li qhov xav tau ntawm bandwidth loj dua;
2. Tus nqi kom zoo dua, kev siv thev naus laus zis tshiab tuaj yeem pab lub network txuas ntxiv kom txo tau cov nqi;
3. Kev sib tw ntau dua thiab muaj peev xwm ua tau ntau dua pab cov neeg muab kev pabcuam hauv network los txhim kho lawv cov kev sib tw;
Yuav ua li cas los tsim 100G lub nroog cheeb tsam network?
Lub network architecture ntawm lub nroog cheeb tsam network feem ntau yog muab faib ua peb txheej: cov tub ntxhais txheej, txheej aggregation thiab txheej nkag. Kev sib txawv ntawm cov thev naus laus zis yog siv rau hauv cov txheej txheem sib sau ua ke thiab cov txheej txheem nkag, uas yog IP RAN thiab PTN, IP chaw nyob thiab routing. Cov qub siv nyob rau hauv tes hauj lwm mobile, yav tas los siv nyob rau hauv broadband tes hauj lwm.
Cov cuab yeej siv tseem ceeb siv hauv 100G cheeb tsam cheeb tsam network
Zoo ib yam li 10G thiab 40G hauv nroog cheeb tsam network, 100G DWDM wavelength division multiplexer yog xav tau ntawm cov tub ntxhais txheej ntawm 100G cheeb tsam cheeb tsam network, thiab optical amplifiers thiab dispersion them nyiaj modules kuj yuav tsum tau nyob rau hauv ib co tshwj xeeb daim ntawv thov.
100G cheeb tsam cheeb tsam network feem ntau siv 100G DWDM CFP coherent optical modules. Nws siv plaub txoj kev, thiab lub wavelength ntawm txhua channel yog tunable hauv DWDM network. Nws kis tau nrog ib leeg-hom duplex jumpers, thiab thaum kawg ua tiav tag nrho tus nqi ntawm 100G ntawm 4 * 25G.
Wavelength division multiplexing yog ib qho tseem ceeb thev naus laus zis, uas tuaj yeem muab cov channel rau 10G, 40G rau 100G hloov kho los ntawm DWDM wavelength division multiplexing platform.
Optical amplifiers yog siv los kov yeej fiber ntau attenuation vim tsis sib npaug ntawm kev faib hluav taws xob kho qhov muag thiab lwm yam, thiab cov khoom siv hluav taws xob dispersion tau dav siv los kov yeej kev cuam tshuam ntawm cov teeb liab.
