Tam sim no, muaj peb yam tseem ceeb ntawmDWDMtechnologies tsim nyob rau hauv tsev thiab txawv teb chaws, uas yog raws li AWG-Arrayed Waveguide Grating, dielectric zaj duab xis lim (TFF) thiab fiber grating (FBG) technology. AWG yog ib qho khoom siv waveguide planar, uas yog ib qho arrayed waveguide grating fabricated ntawm ib nti substrate siv PLC technology. Piv nrog FBG thiab TTF, AWG muaj qhov zoo ntawm kev sib koom ua ke siab, ntau cov channel, tsis tshua muaj qhov tsis zoo, thiab cov khoom siv yooj yim batch automated.
Kev loj hlob ntawm ntau qhov kev suavAWG. Txoj kev loj hlob ntawm ntau lub channel AWG cov cuab yeej ua rau tag nrho siv cov bandwidth loj ntawm optical fibers, 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, ntxiv/poob multiplexing, wavelength routing, thiab lwm yam. AWG kuj tuaj yeem ua ke nrog ntau lub wavelength lasers los tsim ib lub teeb ci ntau lub teeb.
