Kupatsanura mawavelength division multiplexing tekinoroji inotumira masaini e optical ane mawavelength akawanda mune imwe optical fiber. Nheyo huru ndeyekubatanidza masaini e optical (multiplex) emawavelength akasiyana pamagumo ekutumira, kuabatanidza kune imwe optical fiber pamutsetse we optical cable kuti itumirwe, uye kuparadzanisa (demultiplex) masaini e optical emawavelength akabatanidzwa pamagumo ekugamuchira. , uye zvichizogadziriswazve, chiratidzo chekutanga chinodzoserwa uye chinotumirwa kumaterminal akasiyana.
Kuwanda kweWDM wavelength division multiplexing hakusi pfungwa itsva. Pakutanga kwekuonekwa kwekutaurirana kwe optical fiber, vanhu vakaona kuti bandwidth yakakura ye optical fiber inogona kushandiswa pakutumira wavelength multiplexing, asi pamberi pemakore ekuma1990, hapana budiriro huru yakaitika mu tekinoroji iyi. Kukura nekukurumidza Kubva pa155Mbit/s kusvika 622Mbit/s kusvika 2.5Gbit/s System TDM rate yave ichipetwa kane mumakore mashoma apfuura Vanhu havawanzo teerera kune imwe tekinoroji kana imwe tekinoroji iri kufamba nekukurumidza. Makore anosvika 1995. Chikonzero chakakosha chekuchinja kukuru mukuvandudzwa kweWDM system ndechekuti vanhu vakasangana nematambudziko muTDM 10Gbit/s tekinoroji panguva iyoyo, uye maziso mazhinji akatarisa pakuwedzera uye kugadzirisa zviratidzo zve optical. Ndipo chete pakatanga kushandiswa WDM system pasi rese.
