Dens Wavelength Division Multiplexing (Dense Wavelength Division Multiplexing) thev naus laus zis, tseem hu ua DWDM, hais txog kev siv tshuab thev naus laus zis cov ntaub ntawv xa xov. Cov thev naus laus zis no siv lub nthwv dej ntawm lub laser xa mus raws qhov sib luag raws li cov khoom lossis cov hlua kab sib kis. Cov ntaub ntawv raug xa mus rau hauv qhov kho qhov muag fiber. DWDM yog ib feem tseem ceeb ntawm cov kho qhov muag fiber ntau network. Nws tso cai rau IP, ATM, thiab synchronous optical network / synchronous digital sequence (SONET / SDH) cov txheej txheem los nqa e-mail, video, multimedia, cov ntaub ntawv, thiab cov ntaub ntawv suab los ntawm kev sib koom ua ke kho qhov muag fiber txheej.

Densile wavelength division multiplexer (DWDM) yog ua raws cov txheej txheem lim dej thiab cov tswv lag luam uas tsis yog cov hlau tsis sib txuas ua ke micro-optics ntim ntim tsim, hauv ITU wavelengths kom ua tiav txuas thiab nqis txuas. Nws muab ITU cov chaw nruab nrab qhov yoj yoj, tsis muaj qhov cuam tshuam poob qis, kev sib cais channel siab, kev siv hluav taws xob tsawg, cov yam ntxwv dav dav, tsis muaj cov kua nplaum, ua kom muaj cua sov zoo thiab ntseeg tau thiab lwm yam. Hauv kev sib txuas xov tooj sib txuas, nws tuaj yeem siv rau kev txuas lossis downlink kho qhov muag teeb liab.
