Raws li qhov xav tau ntawm huab huab kev pabcuam, qhov muaj koob meej ntawm 100G lub nroog cheeb tsam network yog qhov kev zam, nws tsuas yog lub sijhawm xwb.Nrog rau qhov muaj koob meej ntawm Is Taws Nem, cov ntaub ntawv khiav ntawm MAN nce, thiab lub network bandwidth siab nce. Thawj lub peev xwm ntawm 10G thiab 40G WDM cov khoom siv yog maj mam ua tsis tau raws li qhov xav tau bandwidth siab. Lub 100G WDM ntaus ntawv tuaj yeem nqa tsheb ntau dua, uas yog qhov tsim nyog rau kev siv MAN loj.Dab tsi yog qhov zoo ntawm 100G MAN Network?Nyob rau hauv ib txwm 10G thiab 40G MAN networks, 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 lim muab tus nqi qis thiab yooj yim rau kev xa mus rau point-to-point kev twb kev txuas rau MAN, tab sis nws tsis muaj kev hloov pauv thiab scalability. MAN scheme raws li ROADM yog ib qho yooj yim rau kev khiav lag luam thiab hloov tau yooj yim, tab sis muaj tus nqi siab heev.Tsis zoo li 10G thiab 40G MAN networks, 100G MAN networks ntiav cov tshiab tsim coherent pob khoom kho qhov muag tshuab, uas yog hloov tau yooj yim thiab scalable li ROADM-raws li tes hauj lwm, tab sis tsis kim wavelength xaiv keyboards (WSS) thiab optical filters. Nrog kev pab los ntawm cov thev naus laus zis muaj feem xyuam, 100G MAN tuaj yeem txhawb nqa tsis tsuas yog kis mus rau taw tes xwb, tab sis kuj tseem kis mus rau ntau qhov chaw, ua rau lub network hloov pauv thiab npaj kom tau raws li cov kev xav tau yav tom ntej. Tsis tas li ntawd, 100G MAN muaj qhov zoo hauv qab no:1, muaj peev xwm ntau dua, ib qho fiber ntau kis tau tus nqi mus txog 100G, kom tau raws li qhov xav tau ntau dua bandwidth;2. Tus nqi kom zoo dua: kev siv thev naus laus zis siab tshaj tuaj yeem pab lub network kom tsis tu ncua txo nqi;3. Kev sib tw siab thiab kev nthuav dav siab pab cov neeg muab khoom lag luam txhim kho lawv txoj kev sib tw;Yuav tsim 100G MAN Networks li cas?Lub network architecture ntawm MAN feem ntau muab faib ua peb txheej: txheej txheej txheej, txheej txheej txheej thiab txheej txheej nkag. Nyob rau hauv txheej txheej txheej thiab nkag mus, sib txawv cov thev naus laus zis tau txais yuav, uas yog IP RAN thiab PTN, IP chaw nyob thiab routing. Lub qub yog siv nyob rau hauv mobile network, thiab tom kawg yog siv nyob rau hauv broadband network.Cov khoom siv tseem ceeb yog dab tsi?Zoo ib yam li 10G thiab 40G MAN, 100G WDM Module yog xav tau nyob rau hauv cov tub ntxhais txheej ntawm 100G txiv neej. Hauv qee cov ntawv thov tshwj xeeb, cov khoom siv kho qhov muag kho qhov muag thiab cov kev them nyiaj dispersion kuj xav tau.100G MAN tsuas yog siv 100G DWDM CFP coherent optical module, nws siv plaub txoj kev, txhua qhov channel wavelength tuaj yeem hloov kho hauv DWDM network, thiab ib hom duplex jumper collocation kis tau tus mob, thaum kawg ua tiav tag nrho tus nqi ntawm 100G 4 * 25G.WDM yog ib qho tseem ceeb technology. DWDM platform tuaj yeem muab cov channel rau 10G, 40G rau 100G hloov kho. Optical amplifiers yog siv los kov yeej fiber ntau attenuation tshwm sim los ntawm qhov tsis sib xws ntawm kev faib hluav taws xob kho qhov muag thiab lwm yam, thiab cov khoom siv nyiaj dispersion tau dav siv los kov yeej kev cuam tshuam ntawm cov teeb liab.Optical amplifiers yog siv los kov yeej fiber ntau attenuation tshwm sim los ntawm qhov tsis sib xws ntawm kev faib hluav taws xob kho qhov muag thiab lwm yam, thiab cov khoom siv nyiaj dispersion tau dav siv los kov yeej kev cuam tshuam ntawm cov teeb liab.XausRaws li qhov xav tau ntawm huab huab kev pabcuam, qhov muaj koob meej ntawm 100G lub nroog cheeb tsam network yog qhov kev zam, nws tsuas yog lub sijhawm xwb.
