Optical wavelength division multiplexing tekinoroji inotumira masaini akawanda-wavelength optical masaini mune imwe optical fiber.Nheyo yakakosha ndeyekubatanidza (multiplex) masaini masaini eakasiyana mawavelengths pamagumo ekutumira, kuabatanidza kune imwecheteyo optical fiber pane optical tambo tambo yekutapurirana, uye kupatsanura (demultiplex) masaini masaini eakasanganiswa mawavelengths pamagumo ekugamuchira. ., uye nekuenderera mberi nekugadziriswa, chiratidzo chepakutanga chinodzoserwa uye chinotumirwa kune akasiyana materminal.
WDM wavelength division multiplexing haisi pfungwa itsva.Pakutanga kwekuonekwa kwe optical fiber communication, vanhu vakaziva kuti bandwidth hombe ye optical fiber inogona kushandiswa kune wavelength multiplexing transmission, asi pamberi pe1990s, pakanga pasina kubudirira kukuru mune iyi teknolojia.Kukurumidza kusimukira Kubva pa155Mbit/s kusvika pa622Mbit/s kusvika 2.5Gbit/s System TDM mwero wanga uchikwira zvakapetwa kana mumakore mashoma apfuura. kuvandudzwa kweWDM system ndeyekuti vanhu vakasangana nezvipingamupinyi muTDM 10Gbit / s tekinoroji panguva iyoyo, uye maziso mazhinji akatarisana nekuwandisa uye kugadzirisa kwezviratidzo zvemaziso.Ipapo chete iyo WDM system yaive neyakasiyana siyana yekushandiswa pasirese..
