I-Optical wavelength division multiplexing yitekhnoloji ehambisa imiqondiso ye-multi-wavelength optical kwifiber enye.Umgaqo osisiseko kukudibanisa (i-multiplex) imiqondiso ye-optical ye-wavelengths eyahlukileyo ekupheleni kokuhambisa, ukudibanisa kwi-fiber ye-optical efanayo kumgca wentambo ye-optical yokuhanjiswa, kunye nokwahlula (demultiplex) imiqondiso ye-optical ye-wavelengths edibeneyo ekupheleni kokufumana. ., kwaye iqhubekeke phambili, isignali yoqobo ifunyenwe kwaye ithunyelwe kwiitheminali ezahlukeneyo.
I-WDM wavelength division multiplexing ayisiyonto intsha.Ekuqaleni kokubonakala konxibelelwano lwefiber optical, abantu baqaphela ukuba i-bandwidth enkulu ye-fiber optical ingasetyenziselwa ukuhanjiswa kwe-wavelength multiplexing, kodwa ngaphambi kwe-1990s, kwakungekho yimpumelelo enkulu kule teknoloji.Uphuhliso oluKhawulezayo Ukusuka kwi-155Mbit/s ukuya kwi-622Mbit/s ukuya kwi-2.5Gbit/s System izinga le-TDM liye laphindaphindeka kane kule minyaka imbalwa idlulileyo. uphuhliso lwenkqubo ye-WDM kukuba abantu bahlangabezane nokungaphumeleli kwi-teknoloji ye-TDM 10Gbit / s ngelo xesha, kwaye amehlo amaninzi agxininise ekuphindaphindeni nasekuqhubeni iimpawu ze-optical signals.Kuphela emva koko inkqubo ye-WDM inoluhlu olubanzi lwezicelo emhlabeni jikelele..
