It allows for the simultaneous transmission of multiple data streams over the same fiber, thereby increasing the capacity and efficiency of the communication system. WDM is commonly used in long-haul ...

Optical Add/Drop Multiplexers (OADMs) are used in wavelength-division multiplexing systems for multiplexing and routing fiber optic signals. They selectively add and drop individual or sets of ...

Digital signals can be mixed and matched. There are two types of wavelength division multiplexers. Dense wavelength division multiplexers (DWDM): These devices use optical (analog) multiplexing ...
