Optical wavelength division multiplexing ndiukadaulo womwe umatumiza ma siginecha owoneka bwino amitundu yambiri mu fiber imodzi.Mfundo yayikulu ndikuphatikiza (multiplex) ma siginecha owoneka a kutalika kosiyanasiyana kumapeto kotumizira, kuwaphatikiza ku chingwe chofananira cha chingwe cholumikizira, ndikulekanitsa (demultiplex) ma siginecha owoneka a mafunde ophatikizika pamapeto olandila. ., ndi kukonzedwanso, chizindikiro choyambirira chimabwezedwa ndikutumizidwa kumalo osiyanasiyana.
WDM wavelength division multiplexing si lingaliro latsopano.Kumayambiriro kwa maonekedwe a kuwala kwa fiber kulankhulana, anthu adazindikira kuti bandwidth yaikulu ya kuwala kwa fiber ingagwiritsidwe ntchito pofalitsa mafunde amtundu wambiri, koma zaka za m'ma 1990 zisanafike, panalibe kupambana kwakukulu mu lusoli.Kukula mwachangu Kuyambira 155Mbit/s mpaka 622Mbit/s mpaka 2.5Gbit/s System TDM rate yakhala ikuchulukirachulukira kanayi zaka zingapo zapitazi. chitukuko cha dongosolo la WDM ndikuti anthu adakumana ndi zolepheretsa mu teknoloji ya TDM 10Gbit / s panthawiyo, ndipo maso ambiri adayang'ana pa kuchulukitsa ndi kukonza zizindikiro za kuwala.Pokhapokha pamene dongosolo la WDM linali ndi ntchito zambiri padziko lonse lapansi..
