Wavelength division multiplexing (WDM) yog ib qho kev siv tshuab uas ob lossis ntau dua cov khoom siv kho qhov muag pom ntawm qhov sib txawv wavelengths (nrog ntau cov ntaub ntawv) tau sib sau ua ke ntawm qhov kawg xa tawm los ntawm multiplexer thiab txuas mus rau tib lub fiber ntau optical ntawm cov kab kho qhov muag rau kev sib kis.
CWDM: wavelength spacing ntawm 20 nm, nrog qhov dav wavelength sib nrug.
DWDM: lub sijhawm wavelength yog nruab nrab ntawm 0.2 thiab 1.2nm.
Wavelength division multiplexer feem ntau siv nyob rau hauv ob hom: lim-hommus demux, chip-type AAWG (flat top, Gaussian)
Koj puas paub lub hauv paus ntsiab lus ntawm lim mux demux? Thov saib daim duab hauv qab no
Ntawm Mux kawg, lub teeb ntawm ntau lub wavelengths dhau los ntawm cov lim ib tus zuj zus, tom qab ntawd cuam tshuam thiab txuas rau hauv ib qho fiber ntau rau kev sib kis. Thaum kawg ntawm demux, tag nrho cov wavelengths ntawm lub teeb dhau los ntawm lub lim ua ke, lim tawm ib lub wavelength ntawm lub teeb, xav txog tag nrho lwm cov wavelengths mus rau lim tom ntej, ces lim tawm lub wavelength tom ntej ntawm lub teeb, thiab rov ua cov txheej txheem no, peb tuaj yeem demux tag nrho cov wavelengths. ntawm lub teeb.

AWG yog ib qho khoom siv waveguide planar, uas yog ib qho array ntawm waveguide gratings fabricated rau ntawm ib tug nti substrate siv PLC technology.AWG muaj ob qho tib si tsom thiab dispersion zog, uas yog, cia tib lub wavelength ntawm lub teeb tsom rau ib tug taw tes, thaum rau txawv wavelengths. ntawm lub teeb, tso cai rau kev tsom mus rau kev hloov pauv dispersion. 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 yooj yim los tsim hauv batch automation.
HTF covmus demuxtuaj yeem ua rau ntau hom, thov saib daim duab hauv qab no. Yog tias koj xav tau, peb tuaj yeem kho nws rau koj.
