AWG (Arrayed Waveguide Grating) yog cov cuab yeej nyiam hauv Dense Wavelength Division Multiplexing (DWDM). Ib qho grating tsim los ntawm ib pab pawg ntawm arrayed waveguides nrog qhov sib npaug ntawm qhov sib txawv muaj peev xwm faib tsis tau.
Peb tuaj yeem nkag siab yooj yim AWG raws li kev ntim khoom thiab kev thauj mus los hauv kev lag luam xa khoom sai tam sim no. Nyob rau tib qhov chaw xa ntawv, thaum lub courier sau cov pob ntawv sib txawv ntawm txhua tus neeg, nws yuav txheeb lawv thiab xa lawv mus rau tib qho kev taw qhia. Cov parcels tau muab faib ua ib pawg, thauj mus rau qhov chaw nyob hauv ib qho kev sib koom ua ke, thiab tom qab ntawd muab faib rau cov neeg tau txais kev pab. Nyob rau hauv tus txheej txheem ntawm kev thauj mus los, peb yuav subdivide qhov luaj li cas ntawm lub pob kom siv tau qhov chaw thauj mus los. Yog tias muaj ntau qhov chaw, peb tuaj yeem tau txais cov pob tshiab thiab ntxiv rau hauv nruab nrab. Nws yog ib qho txheej txheem ntawm kev sib koom ua ke thiab sib faib. , Qhov no yog qhov ua haujlwm yooj yim ntawm AWG, ib yam li lub tuam txhab xa khoom tuaj yeem tswj xyuas cov pob twg uas tau muab faib thiab tau txais nyob rau hauv qhov kev taw qhia thiab qhov twg.
Kev loj hlob ntawm multi-channel AWG. Txoj kev loj hlob ntawm ntau-channel AWG cov cuab yeej ua rau tag nrho siv cov bandwidth loj ntawm optical fibers, ua tau zoo dua paub txog kev nthuav dav ntawm kev sib txuas lus fiber ntau, thiab ua tau raws li tib neeg txoj kev xav tau kev sib txuas lus.
Lub hauv paus muaj nuj nqi ntawm AWG yog wavelength multiplexing/separation, uas muaj peev xwm paub wavelength multiplexing/demultiplexing, insertion/division multiplexing, wavelength routing, etc. Los ntawm kev sib txuas nrog optical hloov, xaiv wavelength yog ua tau. AWG kuj tuaj yeem ua ke nrog ntau lub wavelength lasers los tsim ib lub teeb ci ntau lub teeb.
