I-Optical wavelength division multiplexing yiteknoloji edlulisela imiqondiso ye-optical ye-multi-wavelength kwi-optical fiber enye. Umgaqo osisiseko kukudibanisa imiqondiso ye-optical (multiplex) yee-wavelengths ezahlukeneyo kwisiphelo sokudlulisa, ukuzidibanisa kwi-optical fiber efanayo kumgca wekhebula le-optical ukuze zidluliselwe, kwaye zahlule (demultiplex) imiqondiso ye-optical yee-wavelengths ezidibeneyo kwisiphelo sokwamkela. , kwaye ziqhubeke zicutshungulwa, isignali yokuqala iyafunyanwa kwaye ithunyelwe kwii-terminals ezahlukeneyo.
Ukwahlulahlula i-WDM wavelength division ayisiyonto intsha. Ekuqaleni kokubonakala konxibelelwano lwe-optical fiber, abantu baqonda ukuba i-bandwidth enkulu ye-optical fiber ingasetyenziselwa ukudluliselwa kwe-wavelength multiplexing, kodwa ngaphambi kweminyaka yoo-1990, akukho nkqubela inkulu kule teknoloji. Uphuhliso olukhawulezayo Ukusuka kwi-155Mbit/s ukuya kwi-622Mbit/s ukuya kwi-2.5Gbit/s Inkqubo Izinga le-TDM liye landa kane kwiminyaka embalwa edlulileyo Abantu abafane banikele ingqalelo kwenye iteknoloji xa enye iteknoloji ihamba ngokukhawuleza Malunga nowe-1995 Isizathu esibalulekileyo sokuguquka kwenkqubo ye-WDM kukuba abantu badibana nokusilela kwiteknoloji ye-TDM 10Gbit/s ngelo xesha, kwaye amehlo amaninzi agxile kwi-multiplexing kunye nokucutshungulwa kwemiqondiso ye-optical. Kuphela emva koko inkqubo ye-WDM yayineenkqubo ezininzi kwihlabathi liphela. .
