Nyob rau hauv lub tshav pob ntawm kev sib txuas lus tes hauj lwm, txoj kev loj hlob ntawm optical nodes yog revolutionary.Cov nodes ua lub luag haujlwm tseem ceeb hauv kev xa cov ntaub ntawv, lub suab thiab cov teeb liab video, thiab lawv txoj kev loj hlob tau cuam tshuam rau kev ua tau zoo thiab ceev ntawm kev sib txuas lus niaj hnub no.Nyob rau hauv no blog, peb yuav tshawb txog cov evolution ntawm optical nodes thiab lawv lub luag hauj lwm nyob rau hauv kev sib txuas lus network kiv puag ncig.
Lub tswvyim ntawmoptical nodeshnub rov qab mus rau thaum ntxov hnub ntawm fiber optic technology.Thaum xub thawj, cov nodes yog cov khoom siv yooj yim siv los hloov cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob thiab rov ua dua.Lawv ua raws li qhov sib txuas ntawm fiber ntau optic tes hauj lwm thiab ib txwm tooj liab-raws li kev sib txuas lus infrastructure.Txawm li cas los xij, raws li kev siv thev naus laus zis, lub luag haujlwm ntawm optical nodes txuas ntxiv nthuav dav, thiab lawv tau dhau los ua ib qho tseem ceeb hauv kev xa mus rau kev sib txuas lus siab heev.
Ib qho ntawm cov kev nce qib tseem ceeb hauv kev siv tshuab kho qhov muag yog kev koom ua ke ntawm wavelength division multiplexing (WDM) functionality.WDM tso cai rau ntau cov ntaub ntawv ntws mus rau ib txhij dhau ntawm ib qho fiber ntau siv cov wavelengths sib txawv ntawm lub teeb.Cov thev naus laus zis ua kom muaj peev xwm thiab kev ua tau zoo ntawm cov khoom siv kho qhov muag, ua kom muaj kev sib kis ntawm cov ntaub ntawv loj ntawm kev kub ceev.
Lwm txoj kev loj hlob hauv optical node technology yog kev koom ua ke ntawm optical amplifiers.Cov amplifiers no yog siv los ua kom muaj zog ntawm cov teeb liab kho qhov muag, tso cai rau lawv kom xa mus rau ntau qhov kev ncua deb yam tsis xav tau cov khoom siv hluav taws xob kim thiab nyuaj.Kev sib koom ua ke ntawm optical amplifiers rau hauv qhov kho qhov muag tau hloov qhov kev ua si rau kev sib txuas lus nyob deb, ua rau kev xa tawm ntawm cov peev txheej siab, kev sib txuas ceev ceev hauv qhov ntev.
Tsis tas li ntawd, txoj kev loj hlob ntawm optical nodes tau coj mus rau txoj kev loj hlob ntawm reconfigurable optical add-poob multiplexers (ROADMs).Cov khoom siv no tso cai rau cov neeg ua haujlwm hauv lub network kom rov kho qhov chaw kho qhov muag hauv lawv cov tes hauj lwm, ua kom muaj kev faib tawm ntawm bandwidth thiab ua kom yooj yim hauv lub network.ROADM-enabled optical nodes ua lub luag haujlwm tseem ceeb hauv kev xa tawm nrawm, hloov tau cov kev sib txuas lus sib txuas uas muaj peev xwm ua tau raws li qhov xav tau loj hlob rau bandwidth thiab kev sib txuas.
Kev nce qib tsis ntev los no hauv cov thev naus laus zis kho qhov muag pom muaj kev sib koom ua ke ntawm kev txawj ntse software-txhais networking (SDN) muaj peev xwm.Qhov no tso cai rau kev tswj hwm hauv nruab nrab thiab kev tswj hwm ntawm kev sib txuas kho qhov muag, ua kom muaj kev sib koom ua ke ntawm cov peev txheej hauv lub network thiab kev ua haujlwm zoo.SDN-enabled optical nodes pave txoj kev rau kev txhim kho ntawm tus kheej-optimizing thiab kho tus kheej-kho kev sib txuas lus tes hauj lwm, muaj peev xwm hloov mus rau kev hloov network tej yam kev mob nyob rau hauv lub sij hawm.
Nyob rau hauv xaus, txoj kev loj hlob ntawmoptical nodestau ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm kev sib txuas lus network.Los ntawm cov khoom siv hluav taws xob hloov pauv yooj yim mus rau cov khoom siv sib txuas ntse ntse, qhov kho qhov muag tau ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj peev xwm ua tau zoo, kev sib txuas lus ceev ceev.Raws li kev siv thev naus laus zis txuas ntxiv mus, peb tuaj yeem tos ntsoov rau kev hloov kho tshiab hauv kev siv tshuab kho qhov muag, tsav kev txuas ntxiv mus ntawm kev sib txuas lus sib txuas lus thiab tsim lub neej yav tom ntej ntawm kev sib txuas.
