Wavelength division multiplexers and some experimental analysis in the field of optical communication

Light shunting is becoming increasingly popular as the bandwidth required for information transmission in people’s daily lives increases. The main subject of current information research is how to transmit information more efficiently through light. Therefore, wavelength division multiplexing technology appeared. This article will describe the basic principles and some applications of wavelength division multiplexing and then compare the application of partial multiplexing technology in different fields of wavelength division multiplexing technology according to some of the latest three practical experiments. Based on research and comparison, wavelength division multiplexing technology has the advantages of easy reconstruction and good scalability. Still, problems such as immature technology of some required optical components and blurred industry standards make data difficult between experiments.
