WDM wavelength division multiplexing hase khopolo e ncha.Qalong ea ponahalo ea puisano ea fiber optical, batho ba ile ba hlokomela hore bandwidth e kholo ea fiber optical e ka sebelisoa bakeng sa phetisetso ea maqhubu a mangata, empa pele ho lilemo tsa bo-1990, ho ne ho se na katleho e kholo ea theknoloji ena.Nts'etsopele e potlakileng Ho tloha ho 155Mbit/s ho isa ho 622Mbit/s ho isa ho 2.5Gbit/s System TDM sekhahla se ntse se imena habeli lilemong tse 'maloa tse fetileng Batho ha ba ele hloko theknoloji e 'ngoe ha theknoloji e le 'ngoe e ntse e tsamaea ka potlako Hoo e ka bang ka 1995 Lebaka la bohlokoa la phetoho nts'etsopele ea tsamaiso ea WDM ke hore batho ba ile ba thulana le mathata ka theknoloji ea TDM 10Gbit / s ka nako eo, 'me mahlo a mangata a lebisitse tlhokomelo ho multiplexing le ho sebetsana le matšoao a optical.Ke feela moo tsamaiso ea WDM e neng e e-na le mefuta e mengata ea likopo lefatšeng ka bophara..
