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 cholumikizira chingwe cha chingwe cholumikizira, ndikulekanitsa (demultiplex) ma siginecha ophatikizika 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 fiber optical 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. Kukula kwa dongosolo la WDM ndikuti anthu adakumana ndi zovuta muukadaulo wa TDM 10Gbit / s panthawiyo, ndipo maso ambiri adangoyang'ana pakuchulutsa ndi kukonza ma siginecha a kuwala.Pokhapokha pamene dongosolo la WDM linali ndi ntchito zambiri padziko lonse lapansi..
